Ios 在UIWebView中以横向方向播放YouTube视频，而ViewController以纵向方向播放

我正在开发一个需要播放YouTube视频的iPhone应用程序

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

我有一个纵向的ViewController，只有一个加载YouTube视频的UIWebView

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

我想做的是，视频可以横向播放

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

这听起来很简单，但我不知道怎么做。有人能帮我吗

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

谢谢

目前没有办法开始以编程方式播放YouTube视频。

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

也就是说，您可以在ViewController的willRotateToInterfaceOrientation:duration:检查水平方向并使用显示视频缩略图的代码显示网络视图。但用户仍需激活视图。 要删除视频，您可以使用相同的方法，但要选择纵向并删除网络视图。

我找到了答案

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

1） 我将此代码添加到我的viewController.m

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

2） 在interface builder中，我在横向中构建界面，每个元素旋转90°

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

当我构建并运行时，视图似乎处于纵向模式，而实际上是横向模式。因此，嵌入UIWebView中的YouTube视频在横向播放。

这将在AppDelegate中播放。将仅为视频播放器启用水平模式

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {

    if let presentedViewController = window?.rootViewController?.presentedViewController {

        let className = String(describing: type(of: presentedViewController))
        if ["MPInlineVideoFullscreenViewController", "MPMoviePlayerViewController", "AVFullScreenViewController"].contains(className)
        {
            return UIInterfaceOrientationMask.allButUpsideDown
        }

    }
    return UIInterfaceOrientationMask.portrait
}
