* Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: '* -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (NSLayoutConstraint)'
I have a very simple app
One view has one button
I Control Click and dragged the button to a second view and selected MODAL
When I run it in the simulator, everything works
When i run it in my iPad running iOS 5.1.1, it crashes with the error above. I have no idea why and there is no code.
