如何处理tvOS遥控器中的菜单按钮操作

问题描述

我的应用程序面临着一个奇怪的问题。其实当我提出一个视图控制器播放视频。在视频加载时间用户按下菜单按钮，应用程序将转到后台。虽然我已经覆盖了Menu Button Action。

这是我的代码。

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

解决方案

$ p
$ b

 重写func viewWillAppear（_ animated：Bool）{
 super.viewWillAppear（animated）
 let menuPressRecognizer = UITapGestureRecognizer（）
 menuPressRecognizer.addTarget（self，action：#selector（YourViewController.menuButtonAction（recognizer :)） ））
 menuPressRecognizer.allowedPressTypes = [NSNumber（value：UIPressType.menu.hashValue）] 
 self.view.addGestureRecognizer（menuPressRecognizer）
} 
 
 func menuButtonAction识别器：UITapGestureRecognizer）
 {
 self.dismiss（animated：true，completion：nil）
} 
  

I am facing the strange problem with my application. Actually when i am presenting a view controller for play the video. At the video load time user press the menu button the application goes to background. While i have overwrite the Menu Button Action.

This is my code.

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()
 }

解决方案

This is my code and working for me.

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.hashValue)]
    self.view.addGestureRecognizer(menuPressRecognizer)
}

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