UIWebView 中横向模式的 Youtube 视频

我的申请不是为了风景而做的。但是当我打开我的 YouTube 频道时UIWeb视图和一个用户发布视频，它出现在肖像中。我想让它在用户旋转 iPhone 时以横向模式显示。

How to 启用横向模式如本例所示？

我知道有一些“肮脏的黑客”可以做到这一点，但我更喜欢更干净的东西。另外，我不希望 UIWebView 切换为横向，但只是视频可以。

我最终调整了我的视图，使其支持横向模式，使用以下代码：

- (void)viewDidLoad {
    [super viewDidLoad];

    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:)
                                                 name:UIDeviceOrientationDidChangeNotification object:nil];
}

- (void)viewWillAppear:(BOOL)animated {
    UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
    if (UIDeviceOrientationIsLandscape(deviceOrientation))
    {
        //I set my new frame origin and size here for this orientation
        isShowingLandscapeView = YES;
    }
    else if (deviceOrientation == UIDeviceOrientationPortrait)
    {
        //I set my new frame origin and size here for this orientation
        isShowingLandscapeView = NO;
    }
}

- (void)orientationChanged:(NSNotification *)notification
{
    // We must add a delay here, otherwise we'll swap in the new view
    // too quickly and we'll get an animation glitch
    [self performSelector:@selector(updateLandscapeView) withObject:nil afterDelay:0];
}

- (void)updateLandscapeView
{
    UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
    if (UIDeviceOrientationIsLandscape(deviceOrientation) && !isShowingLandscapeView)
    {
        //I set my new frame origin and size here for this orientation
        isShowingLandscapeView = YES;
    }
    else if (deviceOrientation == UIDeviceOrientationPortrait && isShowingLandscapeView)
    {
        //I set my new frame origin and size here for this orientation
        isShowingLandscapeView = NO;
    }    
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait || UIInterfaceOrientationIsLandscape(interfaceOrientation));
}
