Admob interstitial廣告代表

Question

我正在嘗試將代理人分配到admob插頁式廣告，以便我可以處理廣告事件。

GADInterstitialDelegate實現類：

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")
}

}

將代理人分配給廣告：

add.delegate = AdDelegate()

問題是AdDelegate實施類中沒有觸發廣告事件（廣告顯示正確）任何想法為什么？

我不能在與分配給廣告對象相同的類中實現GADInterstitialDelegate，因為廣告對象是在類func中創建的，這會給編譯器錯誤

GADInterstitial委托是一個弱存儲屬性，因此您應該在類中創建一個存儲屬性：

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
}
