确保您的ViewController不包含其他视图控制器对象。例如，如果您的主视图控制器有一个tableview，请不要将UITableViewController放入。它曾用于传递iOS 5，但在iOS 6中它们不允许这样做。

Make sure your ViewController does not contain another view controller object. For example if your main view controller has a tableview, do not put the UITableViewController with in. It this used to pass in iOS 5, but in iOS 6 they will not allow this.
