Question

我正在尝试将代理人分配给admob插页式广告，以便处理广告事件。

GADInterstitialDelegate实施类：

class AdDelegate: NSObject, GADInterstitialDelegate
{
//Interstitial delegate
func interstitial(ad: GADInterstitial!, didFailToReceiveAdWithError error: GADRequestError!) {
    println("interstitialDidFailToReceiveAdWithError:\(error.localizedDescription)")

}

func interstitialDidReceiveAd(ad: GADInterstitial!) {
    println("interstitialDidReceiveAd")

}

func interstitialWillDismissScreen(ad: GADInterstitial!) {
    println("interstitialWillDismissScreen")

}

func interstitialDidDismissScreen(ad: GADInterstitial!) {
    println("interstitialDidDismissScreen")
}

func interstitialWillLeaveApplication(ad: GADInterstitial!) {
    println("interstitialWillLeaveApplication")
}

func interstitialWillPresentScreen(ad: GADInterstitial!) {
    println("interstitialWillPresentScreen")
}

}

将代理人分配给广告：

add.delegate = AdDelegate()

问题是广告事件未在AdDelegate实施类中触发（广告显示正确）任何想法为什么？

我无法在与分配给广告对象相同的类中实现GADInterstitialDelegate，因为广告对象是在类func中创建的，这会给出编译器错误

GADInterstitial delegate是一个弱存储属性，因此您应该在类中创建一个存储属性：

var adDelegate : AdDelegate? // to store the delegate 

func createInterstitial()->GADInterstitial {
    var interstitial = GADInterstitial()
    interstitial.adUnitID = "ca-app-pub-6938332798224330/6206234808";
    adDelegate = AdDelegate()
    interstitial.delegate = adDelegate //delegate is weak so we need to store the property

    return interstitial
}
