iAd 插页式广告因错误而崩溃 "unexpectedly found nil while unwrapping an optional value"

Question

我的 GameScene 中有我的插页式广告代码，每次调用它们时，我都会在标题中收到以下行的错误：

func interstitialAdDidLoad(interstitialAd: ADInterstitialAd!) {
    iAdInterstitialView = SKView()
   iAdInterstitialView.frame = self.view!.bounds //This line
view?.addSubview(iAdInterstitialView)

   interstitialAd.presentInView(iAdInterstitialView)
UIViewController.prepareInterstitialAds()
}

有其他人遇到过这个问题并解决了吗？先感谢您。

Answer 1

这意味着在你的self.view!中展开的值是nil。您可以这样查看：

if let view = self.view {
    iAdInterstitialView.frame = view.bounds
}
