新UIView阻止UITapGesture

Question

我在scrollView的每个页面的后台都有一个视频，启用了分页。我希望在可以看到视频的区域点击时播放/暂停视频（请参阅左下方的图片，包含带有名称和图像的标签的UIView与底部标签栏之间）（视频子视图中还有另一个子视图）每页：热门信息）。用于实现该代码的代码是以下for循环（for循环，因为每个页面都应具有这些属性）：

el.getObject3D('mesh').geometry

如果未添加新的子视图，那会是什么样子：

//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) } 课程作为第一个子视图的基础，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述（例如，微调器不应该重要））：

PlayerView

但是，如果我使用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") } } 类添加子视图，它就不再完全正常工作了。如果黄色区域被轻拍，它仍然可以按照需要运行，但不再在红色区域... ...（图片右侧）为什么它在较低的黄色区域工作，如果红色区域是为什么它不再是它挖？任何人都可以为这个问题提供解决方案（和解释）吗？

Answer 1

新视图位于具有点击手势识别器的视图之上，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其上而不是视频？我不相信你可以直接将UIView添加到视频播放器中。

正如Jake T.所说，轻敲手势识别器正在吸收水龙头，所以你需要做的就是在你的TapGesture声明上添加它

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

有了这个，你就会得到你想要的东西
