SwiftUI 中的 Google AdMob 横幅事件集成答案

【问题标题】：Google AdMob banner event integration in SwiftUISwiftUI 中的 Google AdMob 横幅事件集成

【问题描述】：

我在 swiftUI 中集成了一个带有 UIViewControllerRepresentable 的广告横幅，但我不知道添加像 adViewDidReceiveAd() 这样的事件。我在https://developer.apple.com/tutorials/swiftui/interfacing-with-uikit 上学习过，但事件 adViewDidReceiveAd 从未开始

   struct GADBannerViewController: UIViewControllerRepresentable {

func makeCoordinator() -> GADBannerViewController.Coordinator {
    GADBannerViewController.Coordinator()
   }

func makeUIViewController(context: Context) -> UIViewController {
    let view = GADBannerView(adSize: kGADAdSizeBanner)
    let viewController = UIViewController()
    view.adUnitID = "ca-app-pub-3940256099942544/2934735716"
    view.rootViewController = viewController
    viewController.view.addSubview(view)
    viewController.view.frame = CGRect(origin: .zero, size: kGADAdSizeBanner.size)
    view.load(GADRequest())
    return viewController
}


func updateUIViewController(_ uiViewController: UIViewController, context: Context) {}


class Coordinator: NSObject, GADBannerViewDelegate {
   func  adViewDidReceiveAd(_ bannerView: GADBannerView){
    print("AAAAAAAAA")
    }

   func adView(_ bannerView: GADBannerView, didFailToReceiveAdWithError error: GADRequestError) {
            print(error)
        }


}

}

【问题讨论】：

请参阅 my answer 并告诉我是否可行。
您好，我在“Coordinator(self)”行出现“参数传递给不带参数的调用”错误
并且类型“GADBannerViewController.Coordinator”不符合类协调器的协议“NSObjectProtocol”
请检查您是否遗漏了此处显示的任何内容：developer.apple.com/tutorials/swiftui/interfacing-with-uikit 如果您仍然有问题发布代码，因为没有看到代码的错误消息很难理解。

【解决方案1】：

import SwiftUI
import UIKit
import GoogleMobileAds    

final class GADBannerViewController: UIViewControllerRepresentable  {

    func makeUIViewController(context: Context) -> UIViewController {
        let view = GADBannerView(adSize: kGADAdSizeBanner)
        let viewController = UIViewController()
        view.adUnitID = "ca-app-pub-3940256099942544/2934735713"
        view.rootViewController = viewController
        view.delegate = viewController
        viewController.view.addSubview(view)
        viewController.view.frame = CGRect(origin: .zero, size: kGADAdSizeBanner.size)
        view.load(GADRequest())
        return viewController
    }
    func updateUIViewController(_ uiViewController: UIViewController, context: Context) {}
}

extension UIViewController: GADBannerViewDelegate {
    public func adViewDidReceiveAd(_ bannerView: GADBannerView) {
        print("ok ad")
    }

    public func adView(_ bannerView: GADBannerView, didFailToReceiveAdWithError error: GADRequestError) {
       print("fail ad")
       print(error)
    }
}

【讨论】：

为什么 GADBannerViewController 是一个类？它应该是一个结构。您正在为 0 实用程序增加开销。

【解决方案2】：

我找到了解决方案，我在这里为其他人发布：

import SwiftUI
import UIKit
import GoogleMobileAds


final class GADBannerViewController: UIViewControllerRepresentable  {


    func makeUIViewController(context: Context) -> UIViewController {
        let view = GADBannerView(adSize: kGADAdSizeBanner)

        let viewController = UIViewController()
        view.adUnitID = "ca-app-pub-3940256099942544/2934735713"
        view.rootViewController = viewController
        view.delegate = viewController
        viewController.view.addSubview(view)
        viewController.view.frame = CGRect(origin: .zero, size: kGADAdSizeBanner.size)
        view.load(GADRequest())

        return viewController
    }


    func updateUIViewController(_ uiViewController: UIViewController, context: Context) {}

}







extension UIViewController: GADBannerViewDelegate {
    public func adViewDidReceiveAd(_ bannerView: GADBannerView) {
        print("ok ad")
    }

    public func adView(_ bannerView: GADBannerView, didFailToReceiveAdWithError error: GADRequestError) {
        print("fail ad")
        print(error)
    }
}
