Question

Answer 1

Try something like this. As long as A's frame isn't fullscreen to start with then the animation should just flip A. When you add a subview to a view in a flip transition then it is added to the back of that view, so view A's frame is the one you want to modify.

[UIView beginAnimations:@"flipopen" context:nil];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self cache:TRUE];
[a addSubview:b];
a.frame = b.frame;
[UIView commitAnimations];
