How to get iPhones current orientation?

Question

This is most likely what you want:

UIInterfaceOrientation interfaceOrientation = [[UIApplication sharedApplication] statusBarOrientation];

You can then use system macros like:

if (UIInterfaceOrientationIsPortrait(interfaceOrientation))
{

}

If you want the device orientation use:

UIDeviceOrientation deviceOrientation = [[UIDevice currentDevice] orientation];

This includes enumerations like UIDeviceOrientationFaceUp and UIDeviceOrientationFaceDown
