Question

Everything is fine and the method “shouldAutorotateToInterfaceOrientation” gets called for standard orientations like portrait, portrait-down, landscaperight and landscapeleft. However, I have noticed that it’s not get called on orientations that is when iphone is lying on the table face down or face up. In my code [UIDevice currentDevice].orientation returns some values like 5 and 6 for that but, as I said, the rotation event method isn’t called for those orientations. Am I missing something?

Answer 1

interfaceOrientation The orientation of the application’s user
interface after the rotation. The possible values are described in
UIInterfaceOrientation.

typedef enum {
   UIInterfaceOrientationPortrait           = UIDeviceOrientationPortrait,
   UIInterfaceOrientationPortraitUpsideDown = UIDeviceOrientationPortraitUpsideDown,
   UIInterfaceOrientationLandscapeLeft      = UIDeviceOrientationLandscapeRight,
   UIInterfaceOrientationLandscapeRight     = UIDeviceOrientationLandscapeLeft
} UIInterfaceOrientation;

As you can see the orientations are interface orientations, not device orientations.
