setFont is deprecated

If we compile our old source with >= 3.x versions, we will get this warning..

1.UITableviewCell

old code for version :
cell.font = [UIFont boldSystemFontOfSize: 16];

the new code will be
[cell.textLabel setFont:[UIFont boldSystemFontOfSize: 16]];

2.UIButton

[cell.aButton.titleLabel setFont:[UIFont boldSystemFontOfSize:16]];
