UIDevice currentDevice's “orientation” always null

Question

As per the title. Calling [[UIDevice currentDevice] BeginGeneratingDeviceOrientationNotifications] has no effect.

DidRotateToInterfaceOrientation etc events are wor

Answer 1

UIDevice's notion of orientation seems to be only available on actual devices. The simulator seems to always return 0 here, regardless of whether the notifications have been enabled as the docs suggest. Irritatingly inconvenient, but there you go.

I find this works fine on the actual device:

    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    NSLog(@"orientation: %d", [[UIDevice currentDevice] orientation]);
    [[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
