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.

According to my understanding, a UICollectionView must be in a UICollectionViewController to work properly. However, Xcode won't let me put a search bar in a UICollectionViewController .
