i am using the new xcode 4.5, i have this lines of code on some view controller:
DiscoverCell* cell=[table dequeueReusableCellWithIdentifier:@\"DiscoverCell\
I am using Xcode 4.5 and iPhone simulator 5.0 and it this same error when the first Table was displayed. Following the 'uncheck autolayout' advice, I got it working by Switching the Document Versioning to iOS 5.0. (Storyboard selected -> File Identify tab -> Interface Builder Document -> Document Versioning.) The AutoLayout was already unselected.
