iOS - Programmatically update EKEvent

2011-11-30T04:12:00.000-08:00

The eventIdentifier getting on save is not able to fetch the event using eventIdentifier.

So we are unable to update the EKEvent programmatically even if we have its eventIdentifier

In SimpleEKDemo provided by Apple

log the eventIdentifier on EKEventEditViewDelegate method

- (void)eventEditViewController:(EKEventEditViewController *)controller

didCompleteWithAction:(EKEventEditViewAction)action {

NSError *error = nil;

EKEvent *thisEvent = controller.event;

switch (action) {

case EKEventEditViewActionCanceled:

// Edit action canceled, do nothing.

break;

case EKEventEditViewActionSaved:

// When user hit "Done" button, save the newly created event to the event store,

// and reload table view.

// If the new event is being added to the default calendar, then update its

// eventsList.

if (self.defaultCalendar == thisEvent.calendar) {

[self.eventsList addObject:thisEvent];

}

NSLog(@"thisEvent.id = %@", thisEvent.eventIdentifier);

[controller.eventStore saveEvent:controller.event span:EKSpanThisEvent error:&error];

[self.tableView reloadData];

break;

case EKEventEditViewActionDeleted:

// When deleting an event, remove the event from the event store,

// and reload table view.

// If deleting an event from the currenly default calendar, then update its

// eventsList.

if (self.defaultCalendar == thisEvent.calendar) {

[self.eventsList removeObject:thisEvent];

}

[controller.eventStore removeEvent:thisEvent span:EKSpanThisEvent error:&error];

[self.tableView reloadData];

break;

default:

break;

}

// Dismiss the modal view controller

[controller dismissModalViewControllerAnimated:YES];

}

Run the application on device, we will get the eventIDentifier like :

eventidonsave = 3CB60848-6CCA-43BF-B2C6-9EB9F5CFBBB7:C6CDE9DAA864420BA9A2E02CD886369700000000000000000000000000000000

1. log the event ids in the place of fetching events,

- (NSArray *)fetchEventsForToday {

....

for(EKEvent *eachEvent in events){

NSLog(@"eachEvent.id = %@", eachEvent.eventIdentifier);

}

2. or get the event using event identifier

just added this code on viewDidLoad()

EKEventStore *eventStore1 = [[EKEventStore alloc] init];

EKEvent *event1 = [eventStore1 eventWithIdentifier: eventidonsave ];

if(event1){

NSLog(@"event1 id = %@", event1.eventIdentifier);

}else{

NSLog(@"Not Found");

}

-----

In the case 1, we can see we are getting a different eventIdentifier like 3CB60848-6CCA-43BF-B2C6-9EB9F5CFBBB7:040000008200E00074C5B7101A82E00800000000646C6F747573C3010000000000000000100000000DA068F782418C4880257958003F776C

this is not the same as 'eventidonsave'

So in the case 2, we will get "Not Found".

We are looking for a solution !

How to Remove application from iTunes Connect

2011-09-01T06:20:00.000-07:00

From apple documentation:

Since Rights and Pricing settings are app level settings, when you choose to remove all App Store territory

settings for an app, you will be removing the entire app from the App Store and not just a specific version.

To remove your app from sale on the App Store:

1. Click on the button from your App Summary Page.

2. Click on the link to view specific stores.

3. Click on to uncheck all App Store territories.

4. Click on the button.

After removing all assigned territory checkboxes from your app in the Rights and Pricing section,, the status

changes to Developer Removed from Sale and your app will not be seen on the App Store within 24 hours.

Understanding and Analyzing iOS Application Crash Reports

2011-08-10T05:32:00.000-07:00

Read the App Store Review Guidelines from Apple site.

Read Technical Note TN2151 Understanding and Analyzing Crash Logs

How to symbolicate the crash reports to see the lines in our source code ?

got an answer from stackoverflow

1. Our application need to build with Build Settings -> under Build Options, the value of 'Debug Information Format' key should be "Dwarf with dSYM File"

2. We should keep the source and binary files which we used to submit the application to store

3. Select XCode, window -> organizer. select Archieve. Select the build which we used to submit and 'show in Finder'

4. select the xxx.xarchieve and 'Show contents'. You will get the .dSYM file and the .app file from the contents.

5. put the .app, .dSYM and crash logs files in a folder

6. open Terminal appplication and go to this folder // using cd command

7. execute the command
atos -arch armv7 -o appname.app/appname memory_location_in_the_crashlogs

Unable to connect some MS CRM instance from SOAP UI tool.

2011-06-01T04:04:00.000-07:00

The following soap request is executing well with almost all CRM4 AD instance.

We have one customer with MSCRM 4 AD, but the following request is failed with error 401 Unauthorized access..

We have tried the following request from another language Obj C, its executed successfully and got the response

Why we are unable to connect some CRM instances from Soap UI or by java code ?

//we can provide the CRM 4 instance url privately to test to find whats the difference with others

from Java, we are using Axis to convert the java classes and to execute.

this is the error from java code

-------------------------------------------Added on 2011-11-01---------

The above issue is soap ui is not supporting the ntlm2 authentication.
Also the httpClient-3.1 jar is not supporting the ntlm v2 authentication

We can implement our java code by using the jcifs.jar which is handling the ntlm2 authentication.

So we can call the ntlm class of jcifs from the httpClient-3.1.jar

This process is well written in this site

Distribute iPhone iPad application to users or customers

2011-05-04T08:35:00.000-07:00

Preparing Apps for Distribution

Enterprise apps must be signed with your distribution certificate, and must have a provisioning profile that authorizes devices to use the app. The designated Team Agent for your program membership creates the distribution certificate and provisioning profiles at the online Provisioning Portal.

Generating the distribution certificate involves using the Certificate Assistant (which is part of the Keychain Access application on your Mac OS X development system) to generate a Certificate Signing Request (CSR). You upload the CSR to the iOS Provisioning Portal and receive a distribution certificate in response. When you install this certificate in Keychain, Xcode uses the certificate to sign your app. For detailed instructions, see the iOS Provisioning Portal.

Next, you need to create an enterprise distribution provisioning profile so your users can use your app on their device. You create an enterprise distribution provisioning profile for a specific app or multiple apps.

The designated Team Agent for your enterprise can create enterprise distribution provisioning profiles at the iOS Provisioning Portal at http://developer.apple.com/iphone. See the website for instructions.

Deploying Apps

There are three ways to install apps:

Distribute the app to your users for installation using iTunes.
Have an IT administrator install the app on devices using iPhone Configuration Utility.
Post the app on a secure web server; users access and perform the installation wirelessly.

Installing Apps Using iTunes

Your users use iTunes to install apps on their devices. Securely distribute the app to your users and then have them follow these steps:

In iTunes, choose File > Add to Library and select the file (.app, .ipa, or .mobileprovision). You can also drag the file to the iTunes application icon.
Connect a device to the computer, and then select it in the Devices list in iTunes.
Click the Apps tab, and then select the app in the list.
Click Apply.

If your user’s computers are managed, instead of asking them to add the files to iTunes, you can deploy the files to their computers and ask them to sync their device. iTunes automatically installs the files found in iTune’s Mobile Applications and Provisioning Profiles directories.

Installing Apps Using iPhone Configuration Utility

You can use iPhone Configuration Utility to install apps and profiles on connected devices.

Installing Distribution Provisioning Profiles:

In iPhone Configuration Utility, choose File > Add to Library, and then select the distribution provisioning profile that you want to install.
The profile is added to iPhone Configuration Utility and can be viewed by selecting the Provisioning Profiles category in the Library.
Select a device in the Connected Devices list.
Click the Provisioning Profiles tab.
Select the provisioning profile in the list, and then click its Install button.

Installing Apps Using iPhone Configuration Utility

You can use iPhone Configuration Utility to install apps on connected devices.

In iPhone Configuration Utility, choose File > Add to Library, and then select the app that you want to install.
The app is added to iPhone Configuration Utility and can be viewed by selecting the Applications category in the Library.
Select a device in the Connected Devices list.
Click the Applications tab.
Select the app in the list, and then click its Install button.

Installing Apps Wirelessly

iOS 4 supports over-the-air installation of enterprise applications, letting you distribute in-house software to your users without using iTunes or iPhone Configuration Utility.

Requirements

A secure web server accessible by authenticated users
An in-house iOS app in .ipa file format
An XML manifest file, described in this document
A network configuration that allows the device to access an iTunes server at Apple

Installing the app is simple. Users download the manifest file from your website to their iOS 4 device, which instructs the device to download and install the apps referenced in the manifest.

You can distribute the URL for downloading the manifest file via SMS or email, or by embedding it in another enterprise app you’ve created.

It’s up to you to design and host the website used to distribute apps. You need to make sure that users are authenticated, perhaps using basic auth or directory-based authentication, and that the website is accessible via your intranet or the Internet. The app and manifest can be placed in a hidden directory, or in any other location that’s readable using HTTP or HTTPS.

Preparing an Enterprise App for Wireless Distribution

To prepare your enterprise app for wireless distribution, you build an archived version in the form of a .ipa file, and a manifest file that enables wireless distribution and installation of the app.

In Xcode, you create an app archive using the “Build > Build and Archive” command. Then, in the Archived Applications source in Xcode’s Organizer, select the app and click the “Share Application…” button. Then click the “Distribute for Enterprise…” button. You’ll be asked to provide information for the manifest file that Xcode creates. For information about the manifest file, see below. For more information about building and provisioning apps, visit the iOS Dev Center.

About the Wireless Manifest File

The manifest file is a file in XML plist format. It’s used by an iOS 4 device to find, download, and install apps from your web server. The manifest file is created by Xcode, using information you provide when you share an archived app for enterprise distribution. See “Preparing an Enterprise App for Wireless Distribution.”

A sample manifest file is included at the end of this document. The following fields are required:

Item	Description
URL	The fully qualified HTTP or HTTPS URL of the app (.ipa) file.
display-image	A 57 x 57-pixel PNG image that is displayed during download and installation. Specify the image’s fully qualified URL.
full-size-image	A 512 x 512-pixel PNG image that represents the app in iTunes.
bundle-identifier	Your app’s bundle identifier, as specified in your Xcode project.
bundle-version	Your app’s bundle version, as specified in your Xcode project.
title	The name of the app, which is displayed during download and installation.

Optional Keys

Optional keys you can use are described in the sample manifest file. For example, you can use the MD5 keys if your app file is large and you want to ensure download integrity beyond the error checking normally done during TCP communications.

Constructing your Website

Upload these items to an area of your website that your authenticated users can access:

The app (.ipa) file
The manifest (.plist) file

Your website design is up to you. It can be as simple as a single page that links to the manifest file. When users tap the web link, the manifest file is downloaded, which triggers the downloading and installation of the apps it describes.

Here’s an example link:

Install App

Don’t add a web link to the archived app (.ipa). It’s downloaded by the device when the manifest file is loaded. Although the protocol portion of the URL is itms-services, the iTunes Store is not involved in this process.

Setting Server MIME Types

It may be necessary to configure your webserver so that the manifest file and app file are transmitted correctly.

For Mac OS X Server use Server Admin to add the following MIME types to the MIME Types settings:

application/octet-stream ipa

text/xml plist

For IIS, use IIS Manager to add the MIME type in the Properties page of the server:

.ipa application/octet-stream

.plist text/xml

Troubleshooting Wireless App Distribution

If wireless app distribution fails with an “unable to download” message, check the following:

Make sure the app is signed correctly. Test it by installing it on a device using iPhone Configuration Utility.
Make sure the URL to the app (.ipa) file (in the manifest file) is correct and the app file is accessible to web users.
Make sure the link to the manifest file is correct and that the manifest file is accessible to web users.

Still you are getting the message "unable to download" with Done and Retry button.. Please note that

#. Dont try to manually edit the .plist file. Always give the right values when saving the file as enterprise distribution. If you have mistaked the application url when create enterprise distribution, Again create the application with correct url value instead of editing the manifest file.

Network Configuration Requirements

If the devices are connected to a closed internal network, you should allow iOS devices access to these sites.

URL	Reason
ax.init.itunes.apple.com	The device obtains the current file-size limit for downloading apps over the cellular network. If this site it not reachable, installation may fail.
ocsp.apple.com	The device contacts this site to check the status of the distribution certificate used to sign the provisioning profile. See“Certificate Validation.”

Providing Updated Apps

Apps that you distribute yourself aren’t automatically updated. When you have a new version for users to install, notify them of the update and instruct them to install the app. Consider having the app check for updates and notify the user when it opens. If you’re using wireless app distribution, the notification can provide a link to manifest file of the updated app. You will need to update all of your enterprise apps at least once a year. See “Certificate Validation.”

If you want users to retain data stored on their device, make sure the new version uses the same bundle-identifier key as the one it’s replacing and tell users not to delete their old version before installing the new one. The new version will replace the old one and retain data stored on the device, provided that the bundle-identifiers match.

Certificate Validation

The first time an application is opened on a device, the distribution certificate is validated by contacting Apple’s OCSP server. Unless the certificate has been revoked, the app is allowed to run. Inability to contact or get a response from the OCSP server is not interpreted as a revocation. To verify the status, the device must be able to reach ocsp.apple.com. See “Network Configuration Requirements.”

The OCSP response is cached on the device for the period of time specified by the OCSP server—currently between 3 and 7 days. The validity of the certificate will not be checked again until the device has restarted and the cached response has expired. If a revocation is received at that time, the app will be prevented from running. Revoking a distribution certificate will invalidate all of the applications you have distributed.

An app will not run if the distribution certificate has expired. Currently, distribution certificates are valid for one year. A few weeks before your certificate expires, request a new distribution certificate from the iOS Dev Center, use it create create new distribution provisioning profiles, and then recompile and distribute the updated apps to your users. See “Providing Updated Apps.”

Blackberry device failed to acquire an IP address

2011-01-12T06:21:00.000-08:00

This error comes when try to set up WiFi on a blackberry bold device.

Solved by applying the following solution from blackberry forums
"the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation."

Edit: Feb 9, 2011
Today I faced this same issue again and the above solution didn't work for me :(

After few tries, I tried with restarting the wifi modem and try to connect wifi from device.. Then its connected sucessfully..:))

How to set a tabbarcontroller as rootview controller of UISplitViewController

2010-12-28T01:06:00.000-08:00

When I try to do this, 8 tabitems are displaying without "More" button. so its overlapping items title. And it will display More button if more than 8 tab items.
As it is using width 320, How to set only 5 tabs visible at a time.

I have posted this question in stackoverflaw.com http://stackoverflow.com/questions/4459634/how-to-set-a-tabbarcontroller-as-rootview-controller-of-uisplitviewcontroller

its still an open question. So I think its better to use tabbar instead of tabbarcontroller. But this will change my whole design. :(

How to change Tomcat default character encoding

2010-12-27T06:18:00.000-08:00

We faced an issue last week on linux machine,

In a tomcat deployed server, The non-english characters getting from web services are not displaying correctly.

We write a main program in java and retrieved the data through web-service. its parsed well and correctly displayed the non-english character.

So the issue is with tomcat, after investigation we found this.

In the catalina.bat (catalina.sh) add the java args...

set JAVA_OPTS=-Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8

then all encodings seem to come across as UTF-8 by default..

This resolved the problem.

source: http://marc.info/?l=tomcat-user&m=108576957301771&w=3

----------------------

Added some more info:

Configuring Tomcat's URI encoding

By default, Tomcat uses ISO-8859-1 character encoding when decoding URLs received from a browser. This can cause problems when Confluence's encoding is UTF-8, and you are using international characters in attachment or page names.

Edit conf/server.xml and find the line where the Coyote HTTP Connector is defined. It will look something like this, possibly with more parameters:
<Connector port="8080"/>
Add a URIEncoding="UTF-8" property to the connector:
<Connector port="8080" URIEncoding="UTF-8"/>
Restart Tomcat

iPhone Core Data Encryption - encrypt your sqlite databse

2010-12-13T21:36:00.000-08:00

in IOS4 Apple introduced a new feature NSFileProtectionComplete to encrypt the filesystem.

I found very useful article.

https://nickharris.wordpress.com/2010/07/14/core-data-and-enterprise-iphone-applications-protecting-your-data/

Remember that we can apply this only with Device not with simulator.

And on device you should enable the passcode security under Settings -> General

If you have iTunes login, see the apple video about security

session 209 securing application data in category : Core OS

https://developer.apple.com/videos/wwdc/2010/

-------------

We need to prompt a message to the user if file system is not protected, So
How to know the device is password protected ? or How to know the filesystem(database) is encrypted.?

After update sdk4.2 , I am getting this error..

I found no way to solve.. so creating new project with existing files..

MySql installation asking current Password !!

2010-11-17T09:18:00.000-08:00

Today I met this issue..

Its happened because one guy installed the mysql and now he forgot the password. So we decide to uninstall the existing mysql. and install a fresh one.

But when we try to install its asked current password, and if we click next, its failed at "start service"

we tried to uninstall and remove the directory under program files . but didn't help.. After a little googling found that we have to also remove the MySql data folder inside c:\documents and settings\all users\application data\

Its better to do that, search "MySql" in C drive(or include other drives) and delete all folders.(because in some windows os it would be in another path) And do a fresh install. It will work. :)

static declaration of 'xxx' follows non-static declaration

There may be many reasons for this. one situation if you variable declaration inside the @interface block in the header file. It should be outside.

What's the difference of UIView frame and bounds.

2010-07-27T23:42:00.000-07:00

UIView and its subclasses all have the properties "frame" and "bounds". What's the difference?

The frame of an UIView is the rectangle, expressed as a location (x,y) and size (width,height) relative to the superview it is contained within.
The bounds of an UIView is the rectangle, expressed as a location (x,y) and size (width,height) relative to its own coordinate system (0,0).

NSString constants in Objective C

2010-06-29T05:34:00.000-07:00

Easiest way:

// constants.h
#define MY_CONSTANT @"my_constant"

Better way:

// constants.h
extern NSString * const MY_CONSTANT;
// constants.m
NSString * const MY_CONSTANT = @"const value";

There is also one thing to mention. If you need a non global constant, you should use static keyword.
Example


// in constants.m file
static NSString * const MY_CONSTANT = @"const value";

The following are some interesting article.

resize or scale UIImage

2010-02-12T05:23:00.000-08:00

hi,

we can scale the UIImage to any size using the follwing method

add this code to your .h file

@interface UIImage (INResizeImageAllocator)
+ (UIImage*)imageWithImage:(UIImage*)image
              scaledToSize:(CGSize)newSize;
- (UIImage*)scaleImageToSize:(CGSize)newSize;
@end

add the following to .m file


@implementation UIImage (INResizeImageAllocator)
+ (UIImage*)imageWithImage:(UIImage*)image 
              scaledToSize:(CGSize)newSize;
{
    UIGraphicsBeginImageContext( newSize );
    [image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    
    
    return newImage;
}
- (UIImage*)scaleImageToSize:(CGSize)newSize
{
    return [UIImage imageWithImage:self scaledToSize:newSize];
}

e.g to resize an image

self.resizeimage = [UIImage imageWithImage:actual_image scaledToSize:CGSizeMake(65.0f, 65.0f)];

UIWebView : load local html file

2010-02-11T21:50:00.000-08:00

see this post

Formatting UITextView

2010-02-11T21:32:00.001-08:00

There is no feature to format the text in UITextView

We can use the UIWebView to display the formatted text

The easy two methods are :

1. - (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL

2. - (void)loadRequest:(NSURLRequest *)request

1.
use the html formatted text as input.
e.g:

NSString *htmlText = @"<html><head><meta name=""viewport"" content=""width=320""/></head><body><h3>Header</h3><p>Just for testing n;</p></body</html>";

[webView loadHTMLString:htmlText baseURL:[NSURL URLWithString:@"http://www.apple.com"]];

2. Or we can load a local html file
e.g:

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]isDirectory:NO]]];

Dynamic Height for UITextView / UILabel / UITableViewCell

2010-02-09T05:30:00.000-08:00

we can use this for calculating the height taken by a UILabel or UITextView or we can use this same method to calculate the height of cell according to its content..

CGRect frame1 = CGRectMake(5.0, 100.0, 300.0, 75.0 );
    UITextView *textView = [[UITextView alloc] initWithFrame:frame1];
    textView.font = [UIFont systemFontOfSize:17.0];
    NSString *str  = @"The Lord takes care of me as his sheep; I will not be without any good thing.";
    CGSize        textSize = { 300.0f, 9999.0f };
    CGSize size1 = [str sizeWithFont:textView.font constrainedToSize:textSize lineBreakMode:UILineBreakModeWordWrap];
    textView.text = str;
    frame1.size.height = size1.height;
    textView.frame = frame1;
    [self.view addSubview:textView];
    [textView release];

For UITableView
we can use like

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

{

//calculate the height of the text displayed on this cell using the above method

return MAX(size1.height, kMinRowHeight);

}

PIT Solutions extends Blue Brain association

2010-01-31T09:17:00.000-08:00

Technopark based PIT Solutions to partner Blue Brain Project

THIRUVANANTHAPURAM: PIT Solutions based at the Technopark in Thiruvananthapuram, which focuses on IT solutions to the small and medium sector, has extended its comprehensive IT support to the Blue Brain project.

The project is the first comprehensive attempt to reverse re-engineer the mammalian brain in order to understand brain function and dysfunction through detailed simulations.

PIT Solutions will continue to partner Dr Henry Markram, director of the Swiss Federal Institute’s (EPFL) Brain Mind Institute, for the Blue Brain project. Dr Markram said the mysteries of the mind could be solved, and that it was possible to have a supercomputer that models all the brain’s 100 trillion synapses.

The project attempts to build a computerized copy of a brain, starting with a rat’s brain, and progressing to a human brain, inside one of the world’s most powerful computers. The project hopes to bring into being a mind that will be able to think, reason, express will, lay down memories and perhaps even experience different emotions including love, anger, sadness, pain and joy.

In the above HelloWorld program we are using language Resource, To do this,

File->New->Project, and select "Blackberry Resource File"

give file name to HelloWorldRes.rrh and select the folder sample in our project src path

Finish.

open the file and add these key and values

HELLOWORLD_TITLE as key and value as "HelloWorld !!"
do similar for
HELLOWORLD_CONTENTSTRING
HELLOWORLD_EXITSTRING

Build and Run the Program..

Run As Blackberry Simulator

After Launching Simulator, click the menu key, it will list all Applications, Select our application and open it..

java.lang.OutOfMemoryError: PermGen space on java Tomcat server, linux

2009-11-30T05:17:00.000-08:00

I got this error last day when try to open an jsp page,

server is Tomcat5.5 and os is linux

I found this link http://www.mkyong.com/tomcat/tomcat-javalangoutofmemoryerror-permgen-space/ it was very helpful to fix the issue

1. I just added the following code to my catalina.sh file

JAVA_OPTS="$JAVA_OPTS -XX:MaxPermSize=256m"

You can create jsp page with the following code to evalute your memory details

# <%@ page import="java.lang.management.*, java.util.*" %><%

# response.setContentType("text/html");

# Iterator iter = ManagementFactory.getMemoryPoolMXBeans().iterator();

# while(iter.hasNext()){

# MemoryPoolMXBean item = (MemoryPoolMXBean) iter.next();

# MemoryUsage mu = item.getUsage();

# long used = mu.getUsed();

# long committed = mu.getCommitted();

# long max = mu.getMax();

# %>

# MEMORY TYPE: <%=item.getName()%>

# Used: <%=used%>

# Committed: <%= committed%>

# Max: <%=max%>

# <%}%>

The output look like

localhost

MEMORY TYPE: Code Cache

Used: 4 mb

Committed: 4 mb

Max: 48 mb

------------------------------------

MEMORY TYPE: PS Eden Space

Used: 25 mb

------------------------------------

MEMORY TYPE: PS Perm Gen

Max: 64 mb

------------------------------------

After add this code JAVA_OPTS="$JAVA_OPTS -XX:MaxPermSize=256m"

I got PS Perm Gen size as

MEMORY TYPE: PS Perm Gen
Used: 14 mb

'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section

2009-11-16T02:42:00.000-08:00

This error throws when commitEditingStyle , Usually this exception is appearing when build with >= 3.0 level

When we remove data from sections, and if the section is empty , we have to remove the section also

following is the sample code:
This error throws when commitEditingStyle , Usually this exception is appearing when build with >= 3.0 level

When we remove data from sections, and if the section is empty , we have to remove the section also

following is the sample code:

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete)
{
// modelForSection is a custom model object that holds items for this section.
[modelForSection removeItem:[self itemForRowAtIndexPath:indexPath]];

[tableView beginUpdates];

// Either delete some rows within a section (leaving at least one) or the entire section.
if ([modelForSection.items count] > 0)
{
// Section is not yet empty, so delete only the current row.
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
withRowAnimation:UITableViewRowAnimationFade];
}
else
{
// Section is now completely empty, so delete the entire section.
[tableView deleteSections:[NSIndexSet indexSetWithIndex:indexPath.section]
withRowAnimation:UITableViewRowAnimationFade];
}

[tableView endUpdates];
}
}
courtesy://http://stackoverflow.com/questions/1061071/uitableview-deleting-sections-with-animation

this is the error message I got
'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (3) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted).'

In my case the above solutions didn't work.. :(
I got this error when build the existing source with sdk 3.0 and above..My previous build level was 2.0. Now I want to shift to 3.0 ..

Solved by the following way

The error message describes that, the no.of rows should be same, after delete one row..
It means if you have only one row, and you delete that row, then the remaining row count should be zero

I have used a display like "No Contacts" when my list is empty, to implement this I added an array with size 3 and show that (No Contacts) when ever list is empty

so this is the corrected code in commitEditing style implementation

[arrayData removeObjectAtIndex:indexPath.row];
[tableView beginUpdates];
//this flag is used to check in numberOfRowsinSection(),
//the code would be
// if [arrayData count] == 0 && this flag is true, reset flag and return 0;
// if [arrayData count] == 0 && this flag is false return the array with size 3 to display "No //Contacts"
self.isRowDeleted = YES;
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
[tableView endUpdates];

//this is used to display "No Contacts"
if ([arrayData count] == 0 ){
[tableView reloadData];
}

Hi all, a free software called "HandBrake" can do this ... just google it and download

free screen capture(image or video) software for Mac OS

2009-11-12T21:17:00.000-08:00

For image capture we can use the builtin command+shift+4 functionality, But to do some additional things(like add text, mark some area etc..) with this captured image we can use a free software "Jing" And also we can record video using this Jing

just search "Jing for Mac" in google and download ...enjoy :)

As I am new to Mac OS, I know hot get screen shot in windows machine..we can use "print screen" button or use "Alt"+"Prnt Scrn" button to get active window scrren, and we can paste into MSPaint application and can save..

But in Mac, this is very simple
use "command"+"shift"+"4" buttons, and drag a rectangle using mouse , the selected area would be saved into desktop as a picture#.png file

APNS with java

2009-11-05T23:15:00.000-08:00

I have tested push notification with pushmebaby sample program.. its worked fine.

To send notification from java, I found this
1. download apns.jar from the above link
2.
add apns.jar, commons-lang-2.0.jar files into your build path
the following is the sample program
try{
PayLoad simplePayLoad = new PayLoad();
simplePayLoad.addAlert("My alert message");
simplePayLoad.addBadge(1);
simplePayLoad.addSound("default");
PushNotificationManager.getInstance().addDevice("jijo's iPhone","give device token get from didRegisterForRemoteNotificationsWithDeviceToken delegate");
Device client = PushNotificationManager.getInstance().getDevice("jijo's iPhone");
PushNotificationManager.getInstance().initializeConnection("gateway.sandbox.push.apple.com", 2195, "C:/temp/APNSCertificates.p12", "paawordgivenwhenexport from keychain by click 'export 2 item' menu item", SSLConnectionHelper.KEYSTORE_TYPE_PKCS12);
PushNotificationManager.getInstance().sendNotification(client, simplePayLoad);

}catch(Exception e){

e.printStackTrace();
}
I have also posted the same code as comments on that site

How to create APNSCertificates.p12 file from login keychain

After enable the push on your application from apple site, and install on your machine, you can see the same in keychain.

select the installed push ceritificate and key, right click and select the menu item "Export 2 items"

and give a name ( say: APNSCertificates.p12) .

APNS : no valid 'aps-environment' entitlement string found for application

2009-11-05T20:34:00.000-08:00

It is common to get this error if we are going to implement APNS on our currently running application..

My application runs fine on device, To implement APNS I configure the App Id on iPhone Developer Program also look at how to tab, and also go through this guide

implement APNS on client source
to implement this , there are lot of good tutorial on internet
http://www.z2live.com/push_notifications
http://www.macoscoders.com/2009/05/17/iphone-apple-push-notification-service-apns/
http://ameyashetti.wordpress.com/2009/07/31/apple-push-notification-service-tutorial/

after do all these We have to create a new provisioning profile(or remove the old one and create with same name) and download it and install both xcode and iphone

remove old profile from xcode and iphone and install new profiles

Dont forget to change the "code signing identity" in settings and "Bundle Identifier" in .plist file if you are create new profile

this will solved the above mentioned error

iPhone: create UITabBarController + UINavigationController + UITableViewController

2009-09-25T03:34:00.000-07:00

programmatically create a TabBarController application

We can create application by choose File->New Project ,and select 'window-based application'

Give a name (say tabbarsample) and save the project

create tableviewcontroller file to display when click on tab
File->New File, select UIViewController subclass, and check the UITableViewController subclass
give a name (example MyTableViewController)

create an instance of NSObject file to retrieve data from that class
File->New File, select Objective-C class, and select subclass of NSObject
give file name example DataAccess

After doing these steps, we can see six files in our classes folder

This is the final product :

Its better to show the code in all six files, it will tell the remaining part..

connecting Microsoft Dynamic CRM 3.0 with java code

2009-09-24T22:26:00.000-07:00

hi All, I would like to share my experience to connecting ms crm with java code...

Its not difficult to connect ms crm 3.0 with java code using both ntlm and basic authentication..

First Step: download web service description files(CrmService.asmx, MetadataService.asmx) from Mircosoft Dynamics CRM

And convert to equivalent java classes

create a folder CrmService and execute this command

java -classpath C:\java\axis-1_4\lib\axis.jar;C:\java\axis-1_4\lib\activation.jar;C:\java\axis-1_4\lib\mail.jar;C:\java\axis-1_4\lib\axis-ant.jar;C:\java\axis-1_4\lib\commons-discovery-0.2.jar;C:\java\axis-1_4\lib\commons-logging-1.0.4.jar;C:\java\axis-1_4\lib\jaxrpc.jar;C:\java\axis-1_4\lib\log4j-1.2.8.jar;C:\java\axis-1_4\lib\saaj.jar;C:\java\axis-1_4\lib\wsdl4j-1.5.1.jar org.apache.axis.wsdl.WSDL2Java -v -a -O -1 CrmService.wsdl -o ./CrmService

pause

do the same for metadataservice to convert to java code.

combine both sources..

Create new project in your eclipse, and test login..

For basic authentication , we can use axis1.4 file

To connect with ntlm authentication, we have to edit the client-config.wsdd file in axis1.4 jar, Hope that you all know about this.. please comment if you need further help with this..

/*added on +20101220 */
easy way to edit is: open the axis.jar file with winrar application
go to the folder org->apache->axis->client and open the file client-config.wsdd and edit the following changes and save. check once again the changes are there.

/*********/

The following is the sample client-config.wsdd

<?xml version="1.0" encoding="UTF-8"?>

<deployment name="defaultClientConfig"

xmlns="http://xml.apache.org/axis/wsdd/"

xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

</globalconfiguration>

</deployment>

Along with axis jar, we need these two(commons-httpclient-3.1.jar, commons-codec-1.3.jar) jar files in our class-path to get ntlm authentication

sample code to login

CrmServiceSoapStub stub =  (CrmServiceSoapStub)
new CrmServiceLocator().getCrmServiceSoap(
new URL("http://###.###.#.###/MSCRMServices/2006/CrmService.asmx"));

stub.setUsername("crm\\user");
stub.setPassword("#######");
WhoAmIRequest request=new WhoAmIRequest();
WhoAmIResponse response=(WhoAmIResponse)stub.execute(Request);
System.out.println("----------getBusinessUnitId()--------->"+response.getBusinessUnitId());
System.out.println("----------getUserId()----------------->"+response.getUserId());

//can write on next post about connecting mscrm 4.0 with java code
