Exception on iPad running 5.1


On my iPad 1 running 5.1, when I run the pre-Bronze app I get this error when I select the plus sign (the screen does get darker indicating that the navController is trying to load).

Terminating app due to uncaught exception ‘NSInvalidUnarchiveOperationException’, reason: ‘Could not instantiate class named NSLayoutConstraint’

Runs fine on the iPad 6.0 Simulator.


Got it, I had to unselect “Use Autolayout” in my NIB since it wasn’t 6.0.
