ios - 从一个选项卡移动到另一个选项卡时，游戏视图消失

Question

我有 2 个选项卡，在视图上我有一个游戏视图。当我从一个选项卡移动到另一个选项卡时，游戏视图消失了。ViewDidDisappear方法被调用。如何解决这个问题？

public override void ViewWillAppear(bool animated) { 
    base.ViewWillAppear(animated); 
    if (gameView != null) { 
        gameScene = new CCScene(gameView); 
        gameScene.AddLayer(new GameLayer()); 
        if (gameView.Director.RunningScene != null) { 
            gameView.Director.PopScene(); 
        } 
        gameView.RunWithScene(gameScene); 
    } 
}   

public override void ViewDidDisappear(bool animated) { 
    if (gameView != null) { 
        gameView.Paused = true; 
    } 
}
