     fromViewController's view and the fromViewController's view will be removed from its superview after the
     transition completes. It is important to allow this method to add and remove the views. The arguments to
     this method are the same as those defined by UIView's block animation API. This method will fail with an
     NSInvalidArgumentException if the parent view controllers are not the same as the receiver, or if the
     receiver explicitly forwards its appearance and rotation callbacks to its children. Finally, the receiver
     should not be a subclass of an iOS container view controller. Note also that it is possible to use the
     UIView APIs directly. If they are used it is important to ensure that the toViewController's view is added
     to the visible view hierarchy while the fromViewController's view is removed.
