I have had many successes programming the iPhone in Landscape mode, but I have been unable to get the Apple PageControl demo to run in Landscape mode and render the content correctly. The demo uses the AppDelegate class as an implicit ViewController which manages a UIScrollView, and the AppDelegate creates a set of UIViewControllers for the ScrollView's contents, 1 controller per page. In addition there is a UIPageControl object that the AppDelegate manages.
I can get the demo code to run in Landscape mode, but the contents always render as if they were in portrait mode, so while the simulator displays he device in Landscape mode, the pageControl is always on the side of the screen.
If anyone has gotten the contents to rotate correctly, I would really appreciate an explanation of how you got it to work.
