ios - Switching between three views -

In my application I have a main view controller that has another view controller, flipsideViewController Behind it On pressing a button in the main view, it becomes curled and the user has access to the other view behind it.

Within the flipside view, there is a button that looks at the scene in the third controller, however, the third scene comes behind the main scene and it should take the whole screen.

One page curl is not recommended to show full screen, it only has half or 3/4 screen If you want to change it in Maps.app, then I suggest using "flip horizontal" animation in this case.
