I believe this is an issue with Xcode’s new interface builder. Did you happen to build your .xib using Xcode 4.5’s interface builder? I’ve run into this same problem just now, and I think that’s the problem. My app runs on iOS 6, but not anything older.
And you need to make sure you turn off Use Auto Layout
for your xibs.
That can be done by:
- Open your xib.
- Go to the
File Inspector
tab. - Find the
Interface Builder Document
section on the right toolbar. - Uncheck the
Use Auto Layout
option.
