I have a singleton instance of a custom UIView with a method -(void)display whose job is to animate the custom view in and out on whatever screen is currently being displayed. (kind of like the -show method in UIAlertView).

My question is how do I determine which view is at the top of the UIView hierarchy and currently displayed?

    The “top” of the view hierarchy is a UIWindow. And there can be (and usually is) more than one UIWindow in the application. If you want to have something shown over everything else on the screen, I suggest you implement a custom UIWindow. E.g. UIAlertView is also implemented this way.
