Here you have it: #3655604 – Linetta

Neither of those techniques worked for me. – Libra

What exactly didn't work? We can't help you if you don't tell us what your actual problems are. – Spic

@KurtRevis thanks for your feedback. I realize now that I wasn't accounting for the fact that in landscape, the height effectively becomes the width. – Libra

Answer 1

UIScreen is your friend here.

CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;
CGFloat screenHeight = screenRect.size.height;

Thank you. I realize now that I wasn't accounting for the fact that in landscape, the height effectively becomes the width. – Libra

If you combine the above with UIDevice, you get a nice ENUM that tells you exactly the orientation of the device. UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation; – Curd

Answer 2

CGRect screenBounds = [[UIScreen mainScreen] bounds];

That will give you the entire screen's resolution in points, so it would most typically be 320x480 for iPhones. Even though the iPhone4 has a much larger screen size iOS still gives back 320x480 instead of 640x960. This is mostly because of older applications breaking.

Hope it helps you..
