Question

我在tvOS平台上有转换错误：当我按下＆＃34;输入＆＃34;遥控器上的按钮两次我有双转换到下一个视图控制器。我在ios上解决了这个问题：

//runningService.stopit();
// OR
stopService(RunningService); // user called

boolean iStopped = true;


public void stopit(){
   //stopSelf();
}

public void onDestroy(){
  super.onDestroy();
  if(iStopped){
   // user did it
  }else{
   // system did it
  }
  iStopped = false; // whoever did it , reset it
}

但是在tvOS上，这个解决方案并不起作用，我也不知道为什么。当我双击快速时，我有几个过渡。请帮忙

class ViewController: UIViewController, UINavigationControllerDelegate {
    var segueInProgress: Bool?

    override func viewDidLoad() {
        super.viewDidLoad()
        navigationController?.delegate = self
    }

    override func shouldPerformSegue(withIdentifier identifier: String, sender: Any?) -> Bool {
        return segueInProgress == false
    }

    func navigateShow(to viewController: UIViewController, sender: Any? = self) {
        if self.segueInProgress == true { return }

        if let navigationController = self.navigationController {
            navigationController.show(viewController, sender: sender)
        } else {
            self.show(viewController, sender: sender)
        }
    }

    func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
        // Or like this: self.view.isUserInteractionEnabled = false
        self.segueInProgress = true
    }

    func navigationController(_ navigationController: UINavigationController, didShow viewController: UIViewController, animated: Bool) {
        self.segueInProgress = false
        // Or like this: self.view.isUserInteractionEnabled = true
    }
}

你可以在按下之后禁用按钮，这会阻止用户双击，只需确保如果你需要担心状态回到你的ViewController，你就可以在viewWillAppear上启用它。
