I\'m getting an intermittent crash using Storyboards in iOS 5. Every so often, I get a SIGABRT when I try to instantiate a new object with a view controller from my Storyboard.
Try to use storyboard ID that different from real UIViewController class name.
I was able to fix this by doing a "Reset Content and Settings" in the IPhone Simulator.
Running it in simulator:
Try Simulator -> Reset Content and Settings
On Device
Try deleting and reinstalling the app
Open your .xib file for this controller and right click on "File Owner" and check if you have connected any wrong property or outlets. You will find a small yellow icon on the right side of outlet if it is a wrong one. Just remove that and try.
