iPad Modal View Dismiss Animation Issue

When I present a modal view in iPad, the view comes up from the bottom. But when I dismiss it, it slides of the screen to the left. I'm in landsc开发者_如何学Goape mode and using UIModalPresentationStylePageSheet. How do I make the dismiss animation slide the view back down?
