ios - 如何知道 iOS 8 中的当前 interfaceOrientation？

Question

既然 UIViewController 中的 interfaceOrientation 属性已弃用，那么检测当前设备方向的推荐方法是什么？

Answer 1

您可以使用[UIApplication sharedApplication].statusBarOrientation

请注意 [[UIDevice currentDevice] orientation] 与您的应用程序旋转不完全。文档:

Discussion: The value of the property is a constant that indicates the current orientation of the device. This value represents the physical orientation of the device and may be different from the current orientation of your application’s user interface. See UIDeviceOrientation for descriptions of the possible values.

我会检查 statusBarOrientation 是否有效。
