如何在swift 3中将Swipe Gesture添加到AVPlayer
我正在使用Swift 3，我想向AVPlayer添加滑动手势。 有人告诉我，为了做到这一点，我必须使用另一个视图，并将该视图带到video的顶部 – 所以我做了，这是我的代码:( 但没有工作 ）:(
import UIKit import AVKit import AVFoundation class ViewController: UIViewController , UIAlertViewDelegate { let myFirstButton = UIButton() let mySecondButton = UIButton() var scoreLabel = UILabel() var Player = AVPlayer() var swipeGesture = UIGestureRecognizer() var sView = UIView() override func viewDidLoad() { super.viewDidLoad() //////////// sView.frame = self.view.frame self.view.addSubview(sView) self.view.bringSubview(toFront: sView) //////Swipe Gesture let swipeRight = UISwipeGestureRecognizer(target: sView, action: #selector(self.respondToSwipeGesture)) swipeRight.direction = UISwipeGestureRecognizerDirection.right self.sView.addGestureRecognizer(swipeRight) let swipeLeft = UISwipeGestureRecognizer(target: sView, action: #selector(self.respondToSwipeGesture)) swipeLeft.direction = UISwipeGestureRecognizerDirection.left self.sView.addGestureRecognizer(swipeLeft) let swipeUp = UISwipeGestureRecognizer(target: sView, action: #selector(self.respondToSwipeGesture)) swipeUp.direction = UISwipeGestureRecognizerDirection.up self.sView.addGestureRecognizer(swipeUp) let swipeCustom = UISwipeGestureRecognizer(target: sView, action: #selector(self.respondToSwipeGesture)) swipeCustom.direction = UISwipeGestureRecognizerDirection.init(rawValue: 200) self.sView.addGestureRecognizer(swipeCustom) let swipeDown = UISwipeGestureRecognizer(target: sView, action: #selector(self.respondToSwipeGesture)) swipeDown.direction = UISwipeGestureRecognizerDirection.down self.sView.addGestureRecognizer(swipeDown) //////////////////////End Swipe Gesture let currentPlayerItem = Player.currentItem let duration = currentPlayerItem?.asset.duration let currentTime = Float(self.Player.currentTime().value) if currentTime >= 5 { print("OK") }else if currentTime <= 5 { print("NO") } NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: self.Player.currentItem, queue: nil, using: { (_) in DispatchQueue.main.async { self.Player.seek(to: kCMTimeZero) self.Player.play() } }) ///////////// NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: self.Player.currentItem, queue: nil, using: { (_) in DispatchQueue.main.async { self.Player.seek(to: kCMTimeZero) self.Player.play() DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 5.0) { // check if player is still playing if self.Player.rate != 0 { print("OK") print("Player reached 5 seconds") } } } }) } fileprivate var firstAppear = true //////Swipe Gesture func respondToSwipeGesture(gesture: UIGestureRecognizer) { if let swipeGesture = gesture as?

你的代码有两个错误。
1.在错误的控制器视图上添加手势视图。 你没有在AVPlayerViewController（）中添加手势视图，而是添加了初始控制器，在呈现之后将被AVPlayerViewController（）覆盖。
3.错误的选择器目标你在let swipeRight = UISwipeGestureRecognizer(target: sView, action: #selector(self.respondToSwipeGesture))上做了关于目标的错误假设。 您正在将目标设置为sView并在ViewController上实现选择器方法。
这里target表示选择器方法的目标对象。 因此，将目标更改为self（即视图控制器）将使视图控制器成为选择器方法的目标func respondToSwipeGesture(gesture: UIGestureRecognizer)
请参阅以下更正的代码。

可能你需要正确初始化你的sView。 确保为sView指定了所需的框架，并将其作为子视图添加到self.view中。
override func viewDidLoad() { super.viewDidLoad() sView.frame = self.view.frame self.view.addSubview(sView) self.view.bringSubview(toFront: sView) // add you gestures to sView here ... }
你应该这样做： playerController.view.addSubview(self.sView)而不是self.view.addSubview(sView)
你应该像这样添加self作为tagart： let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(respondToSwipeGesture))
它会工作。 这是我的控制台： https ： //i.stack.imgur.com/agaBx.jpg
