Can anyone confirm that to support both iOS 6 and iOS 5 there is no point to adding the new iOS 6 autorotation methods, since the Apple docs suggest that these methods are completely ignored if you are also implementing the iOS 5 methods?
In particular, I talking about the methods - (NSUInteger)supportedInterfaceOrientations and - (BOOL) shouldAutorotate — that these are ignored and synthesized by the compiler if you also implement the - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
You need to add new callback for autorotation if you are packaging your app in the new sdk. However, these callbacks will be received only when such an app is run on iOS 6 devices. For devices running on earlier iOS versions, earlier callbacks would be received. If you dont implement the new callbacks, the default behavior is that your app runs on all orientation on iPad and all except UpsideDown orientation on iPhone.
