如何在tvOS远程中处理菜单按钮操作

Question

我的申请面临着奇怪的问题。实际上，当我呈现视频控制器播放视频时。在视频加载时，用户按下菜单按钮，应用程序转到后台。虽然我已经覆盖菜单按钮操作。

这是我的代码。

override func viewWillAppear(animated: Bool) {
    let menuPressRecognizer = UITapGestureRecognizer()
    menuPressRecognizer.addTarget(self, action: #selector(VideoPlayerViewController.menuButtonAction(_:)))
    menuPressRecognizer.allowedPressTypes = [NSNumber(integer: UIPressType.Menu.hashValue)]
    self.playerController.view.addGestureRecognizer(menuPressRecognizer)
}

func menuButtonAction(ges:UITapGestureRecognizer) {
    self.dismissView()
 }

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    let menuPressRecognizer = UITapGestureRecognizer()
    menuPressRecognizer.addTarget(self, action: #selector(YourViewController.menuButtonAction(recognizer:)))
    menuPressRecognizer.allowedPressTypes = [NSNumber(value: UIPressType.menu.rawValue)]
    self.view.addGestureRecognizer(menuPressRecognizer)
}

func menuButtonAction(recognizer:UITapGestureRecognizer) {
    self.dismiss(animated: true, completion: nil)
}

    menuPressRecognizer.addTarget(self, action: #selector(YourViewController.menuButtonAction(recognizer:)))
    menuPressRecognizer.allowedPressTypes = [NSNumber(value: UIPressType.menu.rawValue)]
    self.view.addGestureRecognizer(menuPressRecognizer)
}

@objc func menuButtonAction(recognizer:UITapGestureRecognizer) {
    self.dismiss(animated: true, completion: nil)
}

Swift 4.2＆5

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    let menuPressRecognizer = UITapGestureRecognizer()
    menuPressRecognizer.addTarget(self, action: #selector(YourViewController.menuButtonAction(recognizer:)))
    menuPressRecognizer.allowedPressTypes = [NSNumber(value: UIPress.PressType.menu.rawValue)]
    self.view.addGestureRecognizer(menuPressRecognizer)
}

@objc func menuButtonAction(recognizer:UITapGestureRecognizer) {
    self.dismiss(animated: true, completion: nil)
}

Answer 2

指定rawValue时，应使用enum的hash而不是allowedPressTypes：

menuPressRecognizer = [NSNumber(value: UIPressType.menu.rawValue)]

Answer 3

当您想要多个添加多个值时，您可以做到简单：

let pressTypes: [NSNumber] = [UIPressType.select, UIPressType.playPause, UIPressType.rightArrow].map{ NSNumber(value: $0.rawValue)}

Answer 4

这也可以在IB中完成。 TapGestureRecognizer上有一个包含菜单按钮的按钮选项。
