AVPlayercontroller-添加叠加子视图



取决于播放控制可见性如何显示和隐藏添加到contentOverlayView中的自定义子视图?

我想像Youtube TVOS应用程序那样做。

我试过UIPressesEvent,但它没有给我确切的触摸事件。它给了我这些:

  override func pressesBegan(presses: Set<UIPress>, withEvent event: UIPressesEvent?) {
    for item in presses {
        switch item.type {
        case .Menu:
            self.customViews.alpha = 0
        case .PlayPause:
            self.player?.pause()
            self.customViews.alpha = 0
        default:
            self.setVisibilityToPreviewView()
        }
      }
    }
 func setVisibilityToPreviewView () { //This wont work in all cases.
      if self.previewView.alpha == 1 {
         self.previewView.alpha = 0
      } else {
         self.previewView.alpha = 1
      }
    }

但有了这个触摸事件,我只能显示和隐藏子视图。当播放控制隐藏时,应将其隐藏。

如果我得到PlayBackControl Visibility值,我就不必担心隐藏这些子视图。

Apple正在使用AVNowPlayingPlaybackControlsViewController。它不对开发人员开放。

所以我需要找到其他更好的方法来做到这一点。

请指导我如何做。

您可以注册tapGesture识别器,然后将其allowPressTypes属性设置为UIPressType.Select,类似于以下

let tapRecognizer = UITapGestureRecognizer(target: self, action: "onSelect:")
tapRecognizer.allowedPressTypes = [NSNumber(integer: UIPressType.Select.rawValue)];
self.view.addGestureRecognizer(tapRecognizer)

在您的动作按钮中显示或隐藏自定义覆盖。

示例:将此代码添加到视图控制器中,然后点击(在遥控器前面的空白区域选择,触摸区域),您将在控制台上看到一条消息。

override func viewDidLoad() {
        super.viewDidLoad()
        let tapGesture = UITapGestureRecognizer(target: self, action: "onSelect")
        tapGesture.allowedPressTypes = [NSNumber(integer: UIPressType.Select.rawValue)]
        self.view.addGestureRecognizer(tapGesture);
    }
    func onSelect(){
        print("this is select gesture handler method");
    }

更新:以下是将创建AVPlayerController并将tapGestureRecognizer注册到playervc.view.的代码

override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)
        playContent()
    }
    func playContent(){
        let urlString = "<contentURL>"
        guard let url = NSURL(string: urlString) else{
            return
        }
        let avPlayer = AVPlayer(URL: url)
        let playerVC = AVPlayerViewController()
        playerVC.player = avPlayer
        self.playerObj = playerVC
        let tapGesture = UITapGestureRecognizer(target: self, action: "onSelect")
        tapGesture.allowedPressTypes = [NSNumber(integer: UIPressType.Select.rawValue)]
        self.view.addGestureRecognizer(tapGesture);
        playerVC.view.addGestureRecognizer(tapGesture)
        self.presentViewController(playerVC, animated: true, completion: nil);
    }

试试看,我认为它应该很好用。
