我想检查用户是否在低于5.0的iOS上运行应用程序并在应用程序中显示标签.

如何以编程方式检测用户设备上运行的iOS？

谢谢!

我在iOS 7和iOS 8中运行了以下代码:

UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
BOOL landscape = (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight);
NSLog(@"Currently landscape: %@, width: %.2f, height: %.2f", 
      (landscape ? @"Yes" : @"No"), 
      [[UIScreen mainScreen] bounds].size.width, 
      [[UIScreen mainScreen] bounds].size.height);

以下是iOS 8的结果:

Currently landscape: No, width: 320.00, height: 568.00
Currently landscape: Yes, width: 568.00, height: 320.00

与iOS 7中的结果相比:

Currently landscape: No, width: 320.00, height: 568.00
Currently landscape: Yes, width: 320.00, height: 568.00

是否有任何文件指定此更改？或者它是iOS 8 API中的临时错误？
