确定何时在 SwiftUI 中加载 Google 横幅广告

Question

编码在Swift

我已成功将 Google 横幅广告添加到我的应用程序的设置页面。我已经在下面实现了它：

import Foundation
import SwiftUI
import GoogleMobileAds

struct AdView : UIViewRepresentable
{
    @Binding var AdLoaded : Bool

    func makeUIView(context: UIViewRepresentableContext<AdView>) -> GADBannerView
    {
        let banner = GADBannerView(adSize: kGADAdSizeBanner)
        banner.adUnitID = "realAdId"
        banner.rootViewController = UIApplication.shared.windows.first?.rootViewController
        banner.load(GADRequest())
        return banner
    }

    func updateUIView(_ uiView: GADBannerView, context: UIViewRepresentableContext<AdView>){}

    public func adViewDidReceiveAd(_ bannerView: GADBannerView)
    {
        AdLoaded = true
        if (DEBUG_ADS ) { print("Banner Ad Did Find Ad!") }
    }

    public func adView(_ bannerView: GADBannerView, didFailToReceiveAdWithError error: GADRequestError)
    {
        AdLoaded = false
        if (DEBUG_ADS ) { print(error) }
    }
}

我知道因为我在这个结构中没有 GADBannerViewDelegate，所以我无法访问我已经实现的功能（adViewDidReceiveAd 和 adView...didFailToReceiveAdWithError） .他们永远不会按原样被调用。

我搞砸了很多，但我找不到合适的方法来实现这些委托功能。

我的预期功能是在我的设置页面中实现此 AdView，如下所示：

if ( someBindingVariable??? )
{
    AdView(AdLoaded: self.$AdLoaded)
}

它目前的工作方式是在加载 AdView 之前为它保留一个 space。加载广告后，space 中会填满该广告。我希望 space 仅在加载广告后添加。

感谢您的帮助，如果我有什么不清楚的地方，请告诉我！

来自@Asperi 的评论，我用我的 AdView 实现了一个协调器并且它起作用了！

见下文：

import Foundation
import SwiftUI
import GoogleMobileAds

struct AdView : UIViewRepresentable
{
    @Binding public var AdLoaded : Bool
    public var bannerId : String

    func makeCoordinator() -> Coordinator
    {
        Coordinator(self)
    }

    func makeUIView(context: UIViewRepresentableContext<AdView>) -> GADBannerView
    {
        let banner = GADBannerView(adSize: kGADAdSizeBanner)
        banner.adUnitID = bannerId
        banner.rootViewController = UIApplication.shared.windows.first?.rootViewController
        banner.load(GADRequest())
        banner.delegate = context.coordinator
        return banner
    }

    func updateUIView(_ uiView: GADBannerView, context: UIViewRepresentableContext<AdView>){}

    class Coordinator: NSObject, GADBannerViewDelegate
    {
        var parent: AdView

        init(_ parent: AdView)
        {
            self.parent = parent
        }

        func adViewDidReceiveAd(_ bannerView: GADBannerView)
        {
            parent.AdLoaded = true
            if ( DEBUG_ADS ) { print("Ad View Did Receive Ad For ID: \(parent.bannerId)")}
        }

        func adView(_ bannerView: GADBannerView, didFailToReceiveAdWithError error: GADRequestError)
        {
            parent.AdLoaded = false
            if ( DEBUG_ADS ) { print("Ad View Failed To Receive Ad For ID: \(parent.bannerId)")}
        }
    }
}
