However, I then get a message saying: The selection is not a type that can be renamed. Make a different selection and try again.

问题 I am facing a very strange issue with XCode 4.5.

I tried creating a subclass of UITableViewCell and setting the color of the background in all init methods but it still donnot work. PS: XCode 4.5.1 and iOS 5 or 6, same issue.
