UIModalTransitionStyleFlipHorizontal Vertically?

Question

Is it possible to hack the UIModalTransitionStyleFlipHorizontal to be vertical instead of horizontal?

I would normally use a CATransition to do this, but that method requires inserting the view of one UIViewController into the other one, which results in it not being released properly.

So, is it possible without adding one as a subview of another?

Answer 1

You might try using the accepted answer from: UIView vertical flip animation and presenting the modal view half way through the animation. This will require some modification of that code, but it should be possible to do.
