I need to get device orientation from a ViewController. I cannot base on:

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

because it sometimes returns orientation unknown (for example when the device lays on the table).

I just need to know in what orientation is my current UIView displayed (is it landscape left or landscape right). I don't need to have this value updated when orientation changes, I just want to know it, when I ask for it. Just some reference view.orientation ;). Is there something that would help me? I've read UIView documentation, found some reference to UIWindow, but nothing that could help me.

You can also get the device orientation from UIApplication, have you tried using

UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
