Does the same view need to visible in two places at once? Or are you completely removing it before it starts to reappear? If the same view needs to show up at both edges at the same time, then you'll have to make some kind of copy. If the contents won't change during the animation, you could just rasterize your view hierarchy and use that image to act as a placeholder for one of the locations during the animation. If the view will only be in one place at one time, you could do this as a two-stage animation. Set up the animation to cause the view to leave the screen and register yourself as the delegate to get the completion callback. Upon callback, move the view to the other side of the screen (still off screen) and set up an animation to move it back into view. Make sense?
