Question

旋转YouTube视频时遇到问题。我将以下代码添加到我的应用程序中。它适用于iOS 7.但是，它不适用于iOS8。

在我的视图控制器中，我使用了以下代码：

     if(IS_OS_6_OR_LATER){ 
        // I use the following notification for iOS 7
      [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubeStarted:) latername:@"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];//Notification

     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubeFinished:) name:@"UIMoviePlayerControllerWillExitFullscreenNotification" object:nil];//Notification
                }    



if (IS_OS_8_OR_LATER) { 
// I use the following notification for iOS 8
            [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubeStarted:) name:UIWindowDidBecomeVisibleNotification object:self.view.window];
            [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubeFinished:) name:UIWindowDidBecomeHiddenNotification object:self.view.window];
        }



 -(void) youTubeStarted:(NSNotification*) notif {
    //Handle event 
            AppDelegate* appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
            appDelegate.fullScreenVideoIsPlaying = YES;
            NSLog(@"start fullscreen");
        }
        -(void) youTubeFinished:(NSNotification*) notif {
            AppDelegate* appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];//Notification
            appDelegate.fullScreenVideoIsPlaying = NO;//Notification
            NSLog(@"exit fullscreen");//Notification
        }



 -(BOOL) shouldAutorotate {
    //Handle rotate
            NSLog(@"AutoState");
            return NO;
        }
        -(NSUInteger)supportedInterfaceOrientations{
    //Handle rotate
            NSLog(@"AutoState 1");
            return UIInterfaceOrientationMaskPortrait;//Notification
        }
        - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
    //Handle rotate
            NSLog(@"AutoState 2");
            return UIInterfaceOrientationPortrait;//Notification
        }

在iOS 7中，当在横向模式下播放视频时，我按完成按钮，我看到日志＆＃39; AutoState 1＆＃39;但是在iOS 8运行时我看不到这个日志。你可以帮我在iOS 8上解决这个问题吗？非常感谢你

不是将整个应用程序限制为纵向，然后尝试使视频播放器允许横向，而是应该允许整个应用程序中的横向，然后将您的视图控制器（或根视图控制器）限制为仅允许纵向模式，像这样：

在目标设置中，允许应用的横向显示：

在视图控制器中，添加此项以将其限制为纵向：

-(NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

使用iOS8旋转YouTube视频
