UINavigationView in modal view

I would like to place a UINavigation View within a Modal view but I am having loads of problems. I managed to get the modal view working, but when trying to put a UINavigationController in it it just comes up开发者_如何转开发 with a blank screen.

Does anybody know how to do that properly?

Create a UINavigationController, initialize it with your UIViewController at its root, and then present the navigation controller modally.
