I have a UIModalPresentationFormSheet which has a movie player inside of it. When the user hits the button to play it in full screen, my UIModalPresentationFormSheet is still there ontop of the video while it's playing in full screen, behind the window and behind the shadow. What do I need to do to get rid of the dim so the video is playing in fullscreen with being able to select buttons and not having an annoying dim ontop of it?
