iOS:AVPlayerViewController在纵向应用程序中启用全屏旋转

Question

我有一个UIViewcontroller,它包含一个带AVPlayer的AVPlayerViewController.我想为AVPlayerViewController启用旋转(当视频在全屏时)并禁用UIViewController的任何旋转.如何在我的应用中为视频(全屏)启用旋转？

Answer 1

Swift 2.2 在AppDelegate中允许玩家轮换:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
        guard let vc = (window?.rootViewController?.presentedViewController) else {
            return .Portrait
        }

        if (vc.isKindOfClass(NSClassFromString("AVFullScreenViewController")!)) {
            return .AllButUpsideDown
        }

        return .Portrait
    }

当播放器退出全屏模式时,创建并使用AVPlayerViewController的子类返回纵向模式:

class YourVideoPlayer: AVPlayerViewController {

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        if view.bounds == contentOverlayView?.bounds {
UIDevice.currentDevice().setValue(UIInterfaceOrientation.Portrait.rawValue, forKey: "orientation")
        }
    }
