A proper answer will depend on knowing how you are forcing landscape orientation. If you are doing this through UIViewController and company, it should be relatively simple; for other methods probably more complex.
In the simple case, you should be able to override shouldAutorotateToInterfaceOrientation: on your view controller, setup your views in Interface Builder, and set the  UIInterfaceOrientation key to UIInterfaceOrientationLandscapeRight in your Info.plist and be set.
