I have an IOS app that runs in any orientation. But it prefers portrait mode. According to the docs, the simulator should start in the mode set in UIInterfaceOrientation, but it does not.
Here is what I have for a plist:
UISupportedInterfaceOrientations UIInterfaceOrientationLandscapeLeft UIInterfaceOrientationLandscapeRight UIInterfaceOrientationPortrait UIInterfaceOrientationPortraitUpsideDown UIInterfaceOrientation UIInterfaceOrientationLandscapeLeft
