触摸 UIButton 时未调用选择器

Question

我以编程方式创建了 UIButton 并设置了当用户使用遥控器触摸它时调用的方法。下面是我的代码。

import UIKit

class ViewController: UIViewController,VLCMediaPlayerDelegate,UICollectionViewDataSource,UICollectionViewDelegate {

    @IBOutlet weak var btnClick: UIButton!
    @IBOutlet weak var clickBtn: UIButton!
    @IBOutlet weak var myLbl: UILabel!

    @IBOutlet weak var playBtn: UIButton!
    @IBOutlet weak var zoomBtn: UIButton!
    @IBOutlet weak var logoutBtn: UIButton!

    var movieView: UIView! // Add VLC Player on movieView
    var mediaPlayer: VLCMediaPlayer = VLCMediaPlayer() // VLC Media Player
    var PlayButton = UIButton()
    var isZoom:Bool = false

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        self.view.backgroundColor = UIColor( red: CGFloat(68/255.0), green: CGFloat(117/255.0), blue: CGFloat(196/255.0), alpha: CGFloat(1.0))

        self.movieView = UIView()
        self.movieView.backgroundColor = UIColor.black
        self.movieView.frame = CGRect(x: self.view.frame.minX + 400, y: self.view.frame.minY, width: self.view.frame.size.width - 800, height: self.view.frame.height/2)
        self.view.addSubview(self.movieView)
        mediaPlayer.delegate = self
        mediaPlayer.drawable = self.movieView
        let url = "http://192.168.1.34:8852/out.ts"
        let urls = URL(string: url)
        let media = VLCMedia(url: urls!)
        mediaPlayer.media = media
        mediaPlayer.rate = 0
       // mediaPlayer.play()
        self.playButtonTapped(sender: mediaPlayer)

        PlayButton = UIButton(type: .system)
        PlayButton.setTitle("Play", for: .normal)
        PlayButton.frame = CGRect(x: self.view.frame.midX - 100, y: self.view.frame.midY - 300, width: 200, height: 86) //midY-20
        PlayButton.addTarget(self, action: #selector(pressButton), for: .touchUpInside)
      //  PlayButton.setImage(UIImage(named: "pause-button.png"/*"Pause-1.png"*/), for: .normal)
        self.view.addSubview(PlayButton)
       // self.view.bringSubview(toFront: PlayButton)
       // self.view.sendSubview(toBack: mediaPlayer.drawable as! UIView)
    }

    //The target function
    @objc func pressButton(){
        print("Hello")
    }
}

问题是 pressButton 方法从未被调用。

我发现问题出在 tvOS 上的“.touchUpInside”，因为它不符合我们的预期：我们需要改用“.PrimaryActionTriggered”。

谢谢大家的支持
