My application is crashing on iOS 5 when I call presentModalViewController on a new view with the error:
Terminating app due to uncaught exception ‘NSInvalidUnarchiveOperationException’, reason: ‘Could not instantiate class named NSLayoutConstraint’
I know that this error should be fixed by unchecking auto layout, but it isn’t. I unchecked it in all my nibs.
The very puzzling part is that using a view I created one month ago, there is no crash, but using one that I created today, it crashes.
Is there another setting that I should know about?
I’m using XCode 4.5.2, with SDK 6.0, and deployment target 5.0.
I guess you would have solved the problem by now.
