ios - 新的 UIView 阻止 UITapGesture

Question

我的 scrollView 的每一页的背景中都有一个视频，启用了分页。我希望视频在点击可以看到视频的区域时播放/暂停(见左下图，在包含名称和图像标签的 UIView 和底部标签栏之间)(视频 subview 上有另一个 subview 在每页:顶部信息)。用于实现的代码是以下 for 循环(for 循环，因为每个页面都应具有这些属性):

//add subviews (pages)
for (pageIndex, page) in pagesViews.enumerated(){

    //...create pages with views

    //add Subview with videoplayer frame to individual "pages"
    let videoPlayerFrame = CGRect(x: 0, y: 0, width: pageSize.width, height: pageSize.height)
    let videoPlayerView = PlayerView(frame: videoPlayerFrame)
    page.addSubview(videoPlayerView)

    //add Subview with top info frame to individual "pages"
    let postInfoFrame = CGRect(x: 0, y: 0, width: pageSize.width, height: 80)
    let infoView = PostView(frame: postInfoFrame)
    page.addSubview(infoView)

    //WORKS FINE UNTIL HERE


    //NEW SUBVIEW
    //add Subview with bottom info frame to individual "pages"
    let postPropertiesFrame = CGRect(x: 0, y: (pageSize.height - 200) / 2, width: pageSize.width, height: 200)
    let propertiesView = PostPropsView(frame: postPropertiesFrame)
    page.addSubview(propertiesView)

}

如果没有添加新的 subview ，它就是这个样子:

PlayerView 类作为第一个 subview 的基础，当我点击视频区域时视频播放/暂停(阅读评论以首先获得概览(例如微调器不重要)):

lass PlayerView: UIView {

    //create spinner view
    let activityIndicatorView: UIActivityIndicatorView = {

        //define properties
        let aiv = UIActivityIndicatorView(activityIndicatorStyle: .whiteLarge)
        aiv.translatesAutoresizingMaskIntoConstraints = false

        //start spinner
        aiv.startAnimating()

        return aiv

    }()

    //create controls container view containing the spinner
    let controlsContainerView: UIView = {

        //set properties of controls container view
        let controlView = UIView()
        controlView.backgroundColor = UIColor(white: 0, alpha: 1)

        return controlView

    }()

    override init(frame: CGRect){

        super.init(frame: frame)

        //function below this override init
        setupPlayerView()

        //add subview with controls (e.g. spinner)
        controlsContainerView.frame = frame
        addSubview(controlsContainerView)

        //add to subview and center spinner in subview
        controlsContainerView.addSubview(activityIndicatorView)
        activityIndicatorView.centerXAnchor.constraint(equalTo: centerXAnchor).isActive = true
        activityIndicatorView.centerYAnchor.constraint(equalTo: centerYAnchor).isActive = true

        //enable interaction
        controlsContainerView.isUserInteractionEnabled = true

        //function below this override init
        defInteractions()

        //backgorund color of player
        backgroundColor = .black

    }

    //define interactions (doupletap and singletap) 
    func defInteractions (){

        //singletap
        let singleTap = UITapGestureRecognizer(target: self, action: #selector(singleTapDetected(_:)))
        singleTap.numberOfTapsRequired = 1

        //controlsContainerView
        controlsContainerView.addGestureRecognizer(singleTap)
    }

    //define type
    var player: AVPlayer?

    //set playing to false
    var isPlaying: Bool = false

    //PLAY?PAUSE VIDEO WHEN video tapped
    func singleTapDetected(_ sender: UITapGestureRecognizer) {

        //play or pause
        if(!isPlaying){

            //play
            player?.play()
            isPlaying = true

        }
        else{

            //pause
            player?.pause()
            isPlaying = false

        }

    }

    //setup video in background
    func setupPlayerView() {

        //insert url
        let urlString = "https://blurtime.com/images/testvideo.mov"

        //check URL if can be converted to NSURL
        if let videoURL = NSURL(string: urlString){

            //player's video
            if self.player == nil {
                player = AVPlayer(url: videoURL as URL)
            }

            //add sub-layer
            let playerLayer = AVPlayerLayer(player: player)
            self.layer.addSublayer(playerLayer)
            playerLayer.frame = self.frame

            //when are frames actually rendered (when is video loaded)
            player?.addObserver(self, forKeyPath: "currentItem.loadedTimeRanges", options: .new, context: nil)

            //loop through video
            NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: self.player?.currentItem, queue: nil, using: { (_) in
                DispatchQueue.main.async {
                    self.player?.seek(to: kCMTimeZero)
                    self.player?.play()
                }
            })

        }

    }

    //what to do when video is loaded (spinner shall disappear)
    override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {

        //when frames are actually being rendered
        if keyPath == "currentItem.loadedTimeRanges" {

            activityIndicatorView.stopAnimating()
            controlsContainerView.backgroundColor = .clear

        }

    }

    //reuired as suggested by XCode
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

}

但是，如果我用 PostPropsView 类添加 subview ，它就不再完全起作用了。如果点击黄色区域，它仍然可以正常工作，但不再在红色区域中工作......(右图)为什么它在较低的黄色区域工作，如果点击红色区域，为什么它不再工作？任何人都可以为这个问题提供解决方案(和解释)吗？

Answer 1

新 View 位于具有点击手势识别器的 View 之上，并且正在拦截这些触摸，并且没有针对它们的处理程序。

也许创建一个新的 UIView，其中包含 PostPropsView 和您的视频播放器，并将点击手势识别器放在上面而不是视频上？我不相信您可以将 UIView 直接添加到视频播放器。
