Question

我已经尝试了所有教程，但是仍然无法以编程方式向按钮添加操作。

我尝试将功能添加到viewdidload和viewdidappear，但是它不起作用。

class videoPlayer: AVPlayerViewController {
// PROPERTIES
let button = UIButton()
.
.
.
override func viewDidLoad() {
        super.viewDidLoad()
        print("video controller here!")

        //Play the Video
        let url = Bundle.main.path(forResource: "v1", ofType: "mp4")!
        let player = AVPlayer(url: URL(fileURLWithPath: url))
        let playerViewController = AVPlayerViewController()
        playerViewController.player = player
        self.present(playerViewController, animated: true) {
            playerViewController.player!.play()
            playerViewController.showsPlaybackControls = false
        }


        //ADDING CUSTOM UI
        button.setTitle("TEST", for: UIControl.State.normal)
        button.backgroundColor = UIColor.red
        button.sizeToFit()
        button.addTarget(self, action: #selector(self.buttonAction(sender: )), for: .touchUpInside)
        playerViewController.contentOverlayView?.addSubview(button)

    }

    // MARK :- Functions
    @objc func buttonAction(sender :UIButton) {
        print("Button tapped")
    }
.
.
.
}

红色按钮确实出现在左上角，但是单击时什么也没发生。

尝试设置像这样的框架

button.frame = CGRect(x:20,y:20,width:50,height:50)

Answer 2

我发现了问题。在复制一些代码时，我没有意识到我正在创建一个新的avplayercontroller。而是将self.player =玩家设置为有效！

基本上，这些按钮正在显示，但是它们的边界矩形在新创建的avplayercontroller（）下。在avplayercontrolview中创建avplayercontroller对我来说真是愚蠢。

let videoURL = Bundle.main.path(forResource: "v1", ofType: "mp4")!
let player = AVPlayer(url: URL(fileURLWithPath: videoURL))
self.player = player
self.showsPlaybackControls = false
self.player?.play()

Swift 5无法向自定义按钮添加操作（AVPlayerViewController中的addTarget问题）
