问题
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. It seems like a very generic error, but I can't find anyone else that's seen this. Thanks for your help!
SectionLandscapeViewController *sectionViewController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil] instantiateViewControllerWithIdentifier:@"SectionLandscapeViewController"];
And the crash...
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIProxyObject 0xa0fba20> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key sceneViewController.'

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.

I was able to fix this by doing a "Reset Content and Settings" in the IPhone Simulator.
回答3:
Running it in simulator:
Try Simulator -> Reset Content and Settings
On Device
Try deleting and reinstalling the app
回答4:
Try to use storyboard ID that different from real UIViewController class name.
