swift - 没有委托(delegate)，didFailToReceiveAdWithError

Question

我有这个代码:

class ViewControllergame: UIViewController, ADBannerViewDelegate {

 var bannerView:ADBannerView!

 override func viewDidLoad() {
    super.viewDidLoad()
    self.canDisplayBannerAds = true
    bannerView?.delegate = self

    bannerView?.hidden = true
 }

     func bannerViewDidLoadAd(banner: ADBannerView!) {

    bannerView?.hidden = false
}



func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {
    return willLeave
}

func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
    bannerView?.hidden = true

}

}

但它不在 didFailToReceiveAdWithError 中，当我的应用程序进入待机状态时，我收到此错误:

ADBannerView: Unhandled error (no delegate or delegate does not implement didFailToReceiveAdWithError:): Error Domain=ADErrorDomain Code=1 "Service session terminated.

我该如何解决这个问题？

Answer 1

您似乎已经实现了这些方法，但从未调用过它们，因为您的横幅委托(delegate)未设置。如果你只使用 Storyboard

Control-Drag

从您的 ADBannerView 到横幅所在的同一个 ViewController，然后选择“委托(delegate)”Outlet。
