如何在 iOS 中设置视图大小以匹配设备屏幕？
我有一个 UIView，我需要将其大小调整为屏幕高度的一半，它在纵向模式下工作正常，但如果我在横向模式下与 iPad 一起使用应用程序，UIView 总是会获得屏幕纵向尺寸，有什么想法如何获得尺寸发射时和方向改变后？
我尝试以下操作，但总是得到 protrait，其中宽度 = 768 且高度 = 1024
NSLog( @"bounds: %@", NSStringFromCGRect( [UIScreen mainScreen].bounds ) );
NSLog( @"frame: %@", NSStringFromCGRect( [UIScreen mainScreen].applicationFrame ) );
I have a UIView that I need to resize to half the height of the screen, it works fine in Portrait mode but if I lunch the app with the iPad in landscape the UIView always get the screen portrait size, any ideas how to get the size at launch and after change in orientation?
I try the following but always get protrait where width = 768 and height = 1024
NSLog( @"bounds: %@", NSStringFromCGRect( [UIScreen mainScreen].bounds ) );
NSLog( @"frame: %@", NSStringFromCGRect( [UIScreen mainScreen].applicationFrame ) );

尝试将视图的属性
autoresizingMask设置为UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleHeight UIViewAutoresizingFlexibleBottomMargin。或者尝试用它的价值来放置。设置此值后，您的视图将在设备旋转后自动调整大小。
Try to set property
autoresizingMaskof your view toUIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin.Or try to place with its value. After setting this value your view will automatically resize after device rotation.
