如何从上到下为视图设置动画并正确堆叠该视图？

Question

I want to, as properly as possible, animate a view from top to bottom. Then do the appropriate magic to handle memory allocations and such.

In other words, I want an inverse

UIModalTransitionStyleCoverVertical

This modalTransitionStyle pops the view up from bottom, while what I'd like it to do is arrive by airplane.

I've looked into some black magic CATransition , but I can't for the life of me find a proper way of handling memory and dismissing (or "popping off") the view with this method.

A solution as close to "as Steve Jobs intended" is much preferred.

PS: The solution does not need to deal with the view as modal. Actually dealing with it as a new "card" on the stack would be best.

How about UIView
+ (void)transitionFromView:(UIView *)fromView toView:(UIView *)toView duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options completion:(void (^)(BOOL finished))completion

or

+ (void)transitionWithView:(UIView *)view duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion
