Question

好吧所以我有一个应用程序，从菜单视图控制器开始，提示用户按下4个按钮之一，然后加载一个视图控制器，然后呈现一个场景，用户根据按下哪个按钮来玩游戏。 / p>

然后我将用户重定向到另一个视图控制器，一旦满足条件（他们输掉游戏），它就呈现另一个场景。唯一的问题是，第二个视图控制器（我假设它的场景）仍然在运行。我知道这是因为我在其中有一个打印声明覆盖函数更新方法，看看它是否还在那里。

另外，我在我的旧游戏中播放音频，但它目前还在播放。我不会完全记住，因为稍后我会在所有3个视图控制器和它们呈现的场景之间传递音频数据（全部静音）。

现在正在发生的事情的唯一问题是，当我运行应用程序时，因为旧的viewiewcontroller它的场景似乎仍然在下面运行，它一直调用过渡，这导致一个奇怪的外观，当条件满足，转换循环到新的viewcontroller，然后回到转换的开始，然后再次循环到新的viewcontroller。

我已尝试过这段代码：

let theVC = self.viewController?.storyboard?.instantiateViewController(withIdentifier: "TrumpVC") as! TrumpViewController

self.viewController?.navigationController?.pushViewController(theVC, animated: true)

self.viewController?.dismiss(animated: true, completion: {});

但它似乎没有任何帮助:(基本上我导航到一个新的viewcontroller并解除当前的一个（这在我的场景中都是这样）
