UIScreenis your friend here.

UIScreen是你的朋友吗？

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

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.

这将为您提供整个屏幕的分辨率（以点为单位），因此对于 iPhone，它通常为 320x480。即使 iPhone4 有更大的屏幕尺寸，iOS 仍然返回 320x480 而不是 640x960。这主要是因为较旧的应用程序中断。

Hope it helps you..
