屏幕旋转锁定时如何获取设备方向？

Question

I used the notification to get the device's orientation.

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    [notificationCenter addObserver:self  
                                   selector:@selector(deviceOrientationDidChange)           
                                       name:UIDeviceOrientationDidChangeNotification 
                                     object:nil];

But the selector function is not called when the device's screen rotation is locked. Any help?

You can use accelerometer to get values of screen orientation. See this . Also see this blog
