Answer 1

The window may include other UI elements besides your view. The 20 pixel difference in your example is the height of the status bar.

[[UIApplication sharedApplication] statusBarFrame].height;

Neither the window nor screen rotate. Getting their frames and using them for a rotated view will only work if you have switched the height and width.

If you are using a UIViewController, try returning YES from this method:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation; // Override to allow rotation. Default returns YES only for UIDeviceOrientationPortrait
