因此看来using
requestInterstitialAdPresentation仅打算在ADInterstitialPresentationPolicy设置为时使用Automatic。使用实施插页式广告时，您Manual
ADInterstitialPresentationPolicy必须presentInView按自己的时间间隔展示广告。以这种方式展示插页式广告时，它不会加载自己的关闭按钮来关闭自己。因此，我所做的是创建一个，UIView以展示插页式广告，并使用插页式广告委托方法关闭UIView。测试时仍然会出现与从iAd网络接收广告不一致的情况。有时您会收到一个广告，有时无法加载，这使我们可以请求一个新广告，有时则什么也没有发生。这似乎只是iAd插页式广告的本质。
