UIDeviceOrientationDidChangeNotification与UIApplicationDidChangeStatusBarOrientationNotification

Question

两者之间有什么区别？在哪种情况下，我应该使用哪一种？

Answer 1

typedef NS_ENUM(NSInteger, UIInterfaceOrientation) {
UIInterfaceOrientationUnknown            = UIDeviceOrientationUnknown,
UIInterfaceOrientationPortrait           = UIDeviceOrientationPortrait,
UIInterfaceOrientationPortraitUpsideDown = UIDeviceOrientationPortraitUpsideDown,
UIInterfaceOrientationLandscapeLeft      = UIDeviceOrientationLandscapeRight,
UIInterfaceOrientationLandscapeRight     = UIDeviceOrientationLandscapeLeft

}

从上面看，UIInterfaceOrientationLandscapeLeft的差异等于UIDeviceOrientationLandscapeRight，UIInterfaceOrientationLandscapeRight等于UIDeviceOrientationLandscapeLeft。 当设备landscapeLeft时，界面应向右旋转以保持内容不反转。
