如何获取iPhone屏幕尺寸以进行计算？

How to get the iPhone screen size to give calculation?

推荐答案

您可以使用边界实例上的属性：

You can use the bounds property on an instance of UIScreen:

CGRect screenBound = [[UIScreen mainScreen] bounds];
CGSize screenSize = screenBound.size;  
CGFloat screenWidth = screenSize.width;
CGFloat screenHeight = screenSize.height;

大多数人都想要主屏幕；如果您有连接到电视的设备，则可能要遍历UIScreens并获取每个设备的界限。

Most people will want the main screen; if you have a device attached to a TV, you may instead want to iterate over UIScreens and get the bounds for each.
