YouTube嵌入式播放器方向



首先要感谢谷歌开发者,让他们可以轻松地将嵌入式播放器添加到iOS项目中。 我的问题是如何改变方向。

最初,我仅在常规设置中将项目设置为"纵向"。 这适用于所有视图控制器,但它也适用于YouTube播放器。 视频按预期播放,但是当我旋转手机时,视频保持纵向。

如果我返回常规设置并将其设置为横向,则播放器将正确旋转(但项目中的所有视图控制器也是如此(。

我已经在这里阅读了有关如何释放 1 个特定控制器的方向的其他答案,但我只想在全屏观看视频时旋转工作。 如果用户决定只在我创建的 UIView 中观看视频,那么我希望锁定方向。

我已经按照 https://developers.google.com/youtube/v3/guides/ios_youtube_helper 的说明进行操作,因此除此之外我需要添加的唯一代码是:

[self.playerView loadWithVideoId:videoSourceID];
就像我说的,视频播放没有错,

让视频全屏没有错,我关心的只是方向。

TLDR:所以基本上,如果用户全屏观看YouTube视频,我只想解锁"横向旋转",应用程序中的其他所有内容都应该锁定为纵向(包括UIView显示窗口视频的视图控制器(。 感谢您的观看!

将此代码粘贴到 AppDelegate.m 上:

- (UIViewController*)topViewController {
return [self topViewControllerWithRootViewController:[UIApplication sharedApplication].keyWindow.rootViewController];
}
- (UIViewController*)topViewControllerWithRootViewController:(UIViewController*)rootViewController {
// Handling UITabBarController
if ([rootViewController isKindOfClass:[UITabBarController class]]) {
    UITabBarController* tabBarController = (UITabBarController*)rootViewController;
    return [self topViewControllerWithRootViewController:tabBarController.selectedViewController];
}
// Handling UINavigationController
else if ([rootViewController isKindOfClass:[UINavigationController class]]) {
    UINavigationController* navigationController = (UINavigationController*)rootViewController;
    return [self topViewControllerWithRootViewController:navigationController.visibleViewController];
}
// Handling Modal views
else if (rootViewController.presentedViewController) {
    UIViewController* presentedViewController = rootViewController.presentedViewController;
    return [self topViewControllerWithRootViewController:presentedViewController];
}
// Handling UIViewController's added as subviews to some other views.
else 
{
    for (UIView *view in [rootViewController.view subviews])
    {
        id subViewController = [view nextResponder];    // Key property which most of us are unaware of / rarely use.
        if ( subViewController && [subViewController isKindOfClass:[UIViewController class]])
        {
            return [self topViewControllerWithRootViewController:subViewController];
        }
    }
    return rootViewController;
    }
}

在以下方法中,您可以决定每个UIView控制器的方向。把它放在你的AppDelegate.m上

- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
id presentedViewController = [self topViewController];
NSString *className = presentedViewController ? NSStringFromClass([presentedViewController class]) : nil;
if (window && [className isEqualToString:@"FullScreenViewController"]) { //FullScreenViewController should support all orientations. Put the exact name of the viewcontroller displayed when the video is fullscreen
    return UIInterfaceOrientationMaskAll;
} else {
    return UIInterfaceOrientationMaskPortrait; //Every other viewcontroller will support portrait only
}
}

您必须检测视频全屏显示的UIView控制器的确切名称。您必须在堆栈跟踪中找到它,并输入它的名称而不是我作为示例编写的"FullScreenViewController">

Swift 3.0

class AppDelegate
    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        guard UIApplication.currentVC.isMovie else { return application.supportedInterfaceOrientations(for: window) }
        return UIInterfaceOrientationMask.allButUpsideDown
    }
}

extension UIApplication {
    struct currentVC {
        static var isMovie: Bool {
            guard let presentedViewController = UIApplication.shared.keyWindow?.rootViewController?.presentedViewController else { return false }
            let className = String(describing: type(of: presentedViewController))
            return ["MPInlineVideoFullscreenViewController",
                    "MPMoviePlayerViewController",
                    "AVFullScreenViewController"].contains(className)
        }
    }
}

import AVKit
extension AVPlayerViewController {
    open override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        UIDevice.current.setValue(UIInterfaceOrientationMask.portrait.rawValue, forKey: "orientation")
    }
}
