I found that when pushing a GKImageCropViewController onto a UINavigationController stack that is not a UIImagePickerController the animation is off. Presumably UIImagePickerController is doing something in it's viewWillDissapear:animated: implementation.
By moving the line to hide the NavigationBar to viewWillAppear:animated: GKImageCropViewController will animated well when we push it onto a UIImagePickerController or a regular UINaviationController stack.
