ios - GADBannerViewDelegate 不会在 Swift 中触发 adViewDidReceiveAd

Question

我在另一个名为 Tools 的类中使用 GADBannerView。但 adViewDidReceiveAd 委托(delegate)方法不会在 Tools 类中触发。我能做什么？

class Tools: NSObject, GADBannerViewDelegate {

    var viewController: UIViewController!

    func showAds(viewController: UIViewController) -> Void {

        self.viewController = viewController

        let request: GADRequest = GADRequest()
        request.testDevices = [kGADSimulatorID]

        let bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
        bannerView.delegate = self
        bannerView.rootViewController = viewController
        bannerView.adUnitID = "ca-app-pub-xxx-xxx"
        bannerView.loadRequest(request)

    }

    func adViewDidReceiveAd(bannerView: GADBannerView!) {
        print("adViewDidReceiveAd");
        viewController.view.addSubview(bannerView)
    }
}

而且，我在 ViewController 中调用了 Tools

override func viewDidLoad() {
    super.viewDidLoad()        
    Tools().showAds(self);
}

在我的例子中..改变

func adViewDidReceiveAd(_ bannerView: GADBannerView) {
  print("adViewDidReceiveAd")
}

到

func bannerViewDidReceiveAd(_ bannerView: GADBannerView) {
  print(#function)
}
