Monotouch - iPhone 静态加载 Admob 插页式广告

Question

我正在尝试使用静态类加载 Admob 插页式广告，以便在合适的时间显示它。

我创建了一个加载插页式广告的方法：

public static void GetInterstitial()
    {
        interstitial = new GADInterstitial ();
        interstitial.AdUnitID = "my_ad_unit_id";

        interstitial.LoadRequest (GADRequest.Request);

        interstitial.DidReceiveAd  += (sender, args) => {
            didInterstitialLoad = true;
        } ;

        interstitial.DidFailToReceiveAd += (object sender, GADInterstitialDidFailToReceiveAdWithErrorEventArgs e) => {
            didLoadInterFailed = true;
        };

        interstitial.DidDismissScreen += (sender, e) => {
            //TODO - Handle interstitial dismiss ();
        };
    }

然后在我的 ViewController 中：

if (isInterstitialLoaded) {
            interstitial.PresentFromRootViewController(this.NavigationController);
        }

这是第一次工作，但之后我在 interstitial.DidFailToReceiveAd 中收到以下错误：

不会发送请求，因为已使用插页式对象

有什么办法可以解决？

Answer 1

当我尝试interstitial.PresentFromRootViewController(this.NavigationController); 时出现此错误

解决方案是在关闭最后一个插页式广告后重新创建整个插页式广告。因此，在您的 DidDismissScreen 处理程序中，再次创建它：

    didInterstitialLoad = false;

    interstitial = new GADInterstitial ();
    interstitial.AdUnitID = "my_ad_unit_id";

    interstitial.LoadRequest (GADRequest.Request);

    interstitial.DidReceiveAd  += (sender, args) => {
        didInterstitialLoad = true;
    };

嗨 :)
