You need to set the delta value for all the controls followed by increasing the origin x to 20pix for all the controls.
Step 1: Increase origin y to 20 pixel (for all the controls in the .xib)
step 2 . And set delta y to - 20 for all the controls in Xib.
Step 3 . Finally change the view as version in interface builder.
If your adding the controls programmatically you need to handle the frames (increase the y position based on the version ) of the added controls like this
if([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0f)
{
[_programmaticallyAddedControl setFrame:CGRectMake(20, 36, 176, 428)];
}
else
{
[_programmaticallyAddedControl setFrame:CGRectMake:CGRectMake(20, 56, 176, 428)];
}
