【问题描述】：

我在 UIWebView 中使用嵌入式 youtube，我的视图控制器处于纵向模式，但我无法在全屏横向模式下看到视频。我尝试了 Stackoverflow 的许多解决方案，但没有一个适用于 iOS 7。

【解决方案1】：

当我遇到与你类似的问题时，我所做的是：

即使是纵向的，你也可以获得设备方向。
如果方向是横向，您可以通过旋转来变换状态栏，与 MPMoviePlayerController 相同。

这是我使用的代码（虽然它适用于 iOS6，所以可能会有所不同

-(void) receivedRotate: (NSNotification*) notification
{
    UIViewController *topController = [UIApplication sharedApplication].keyWindow.rootViewController;
    //Using this part to find the view controller on top (the one that's showing the video in fullscreen).

    while (topController.presentedViewController) {
        topController = topController.presentedViewController;
    }

    //After a little testing, the class of that controller is MPInlineVideoFullscreenViewController
    if ([topController isKindOfClass:NSClassFromString(@"MPInlineVideoFullscreenViewController")]) {
        topController.view.transform = CGAffineTransformMakeRotation(M_PI_2);

        //The 20 and -20 are to prevent the movie from going over the status bar
        topController.view.frame = CGRectMake(0, 20, self.view.frame.size.width,self.tabBarController.view.frame.size.height - 20);
    }
}

这是行不通的，因为你没有努力去理解你必须做什么。您应该学习如何调试项目（在这种情况下，我 100% 确定您甚至没有查看此功能是否正在执行）
没有。您应该添加旋转手势通知识别器。
thanx @LordZsolt NSClassFromString(@"MPInlineVideoFullscreenViewController") 为我工作...

【解决方案2】：

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.


    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(receivedRotate:) name:UIDeviceOrientationDidChangeNotification object:nil];
}

- (void)dealloc{

    [[NSNotificationCenter defaultCenter]removeObserver:self];
}

-(void) receivedRotate: (NSNotification*) notification
{


        UIViewController *topController = [UIApplication sharedApplication].keyWindow.rootViewController;
        //Using this part to find the view controller on top (the one that's showing the video in fullscreen).

        while (topController.presentedViewController) {
            topController = topController.presentedViewController;
        }



        if ([topController isKindOfClass:NSClassFromString(@"AVFullScreenViewController")]) {

            switch ([UIDevice currentDevice].orientation) {
                case UIDeviceOrientationFaceUp:
                    NSLog(@"UIDeviceOrientationFaceUp");
                    break;
                case UIDeviceOrientationFaceDown:
                    NSLog(@"UIDeviceOrientationFaceDown");
                    break;
                case UIDeviceOrientationLandscapeLeft:
                    NSLog(@"UIDeviceOrientationLandscapeLeft");
                    topController.view.transform = CGAffineTransformMakeRotation(M_PI_2);
                    break;
                case UIDeviceOrientationLandscapeRight:
                    NSLog(@"UIDeviceOrientationLandscapeRight");
                    topController.view.transform = CGAffineTransformMakeRotation(-M_PI_2);
                    break;
                default:
                    break;
            }


            topController.view.frame = CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width,[[UIScreen mainScreen] bounds].size.height);
        }

}
