Simple sliding transitioning for navigation controller mimics pre iOS7 push/pop animations.All you need, is simply set delegate for you navigation controller: self.navigationController.delegate = self.navigationTransitioningDelegate;NavigationController does not retain delegate, so you should hold it. Note: this code is free (http://unlicense.org)
