A question here: Xcode 4.5 corrupting XIBs? illustrates the problem and solution for xcode 4.5 creating nib files that can not run on ios5.
Does anyone have a solution to prevent the auto layout checkbox from being defaulted to on? I'm worried that in the process of development, I will forget to unchecked that box.
回答1:
There's a way, but it's kinda convoluted and, I might add, not recommended.
You can open your template files located in:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/File Templates/User Interface/, in each directory, there are .xib files. They are XML files, open them with a text editor.
Replace the following line:
<bool key="IBDocument.UseAutolayout">YES</bool>
to
<bool key="IBDocument.UseAutolayout">NO</bool>
I will repeat though, this is not recommended.

There is a project templates folder, you should modify the xib files there too.
Also if you want to disable auto layout in storyboards, you should change this attribute:
useAutolayout="YES"
in each storyboard file to NO.
