运行如何在 xcode 中多次运行？

Question

我想在玩家死亡后展示我的插页式广告。这意味着插页式广告将在我的游戏结束场景中加载。但是我不能只在 viewdidload 部分写函数名。那么，当玩家到达 gameOverScene 时，有没有办法让我运行我的 interstitialAd 功能？

如果有更新函数，我会像这样创建一个布尔值：

var interstitialAdShow = false

然后在我的 didmovetoview 中写下：

interstitalAdShow = true

然后在我的更新函数中：

If interstitailAdShow == true{
     interstitial.present(fromRootViewController: self)
}

但是现在，当 GameViewController 中没有更新功能时，我无法在我的 gameOverScene.swift 中执行此操作，我无法使用此解决方案，还有其他方法可以触发我的插页式广告吗gameOverScene 出现时的广告功能。

顺便说一句，这是我的代码

一种方法是使用回调，这是一种将创建新 class(场景) 的 class 发送到新 class(场景) 的方法作为论据。这样新的 class(scene) 可以调用旧的 class 的函数。下面是如何在您的代码中实现它。首先，我制作了一个自定义初始化程序，它将创建的 class 作为参数并将其分配给局部变量 (myCreator)。然后在玩家死亡时调用的函数中（deathFunction()），我从创建 class 调用 runIntersitialAd() 函数。我还更改了从 GameViewController 设置 MenuScene 的代码，以将其自身（GameViewController class）作为 MenuScene 初始化中的参数发送。

将场景 class 更改为如下所示：

class MenuScene {
    var myCreator : GameViewController!

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    convenience init(fileNamed: String, VCwhoCreatedMe: GameViewController) {

       self.init(fileNamed: fileNamed, VCwhoCreatedMe: VCwhoCreatedMe)
       myCreator = VCwhoCreatedMe
    } 

    ....your other code

    deathFunction() { //whatever code you use when the player dies
       myCreator.runTheInterStitialAd() //because of the callback construction this is now possible.
       ...other code
    }
}

在你的 GameViewController 中，函数 viewDidLoad():

if let view = self.view as! SKView? {

   if let scene = MenuScene(fileNamed: "MenuScene",VCwhoCreatedMe: self ) {
       runTheInterStitialAd()

       scene.scaleMode = .aspectFill


       view.presentScene(scene)    
       ..... other code    
   }
}
