确定在SwiftUI中何时加载Google横幅广告

这是用Swift编码的

我已成功地将谷歌横幅广告添加到我的应用程序的设置页面。我已实施了以下措施：

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) }
    }
}

它当前的工作方式是在加载AdView之前为其留出空间。一旦广告被加载，空间就会被广告填满。我希望空间只在广告加载后才被添加

谢谢你的帮助，如果我有什么不清楚，请告诉我

在@Asperi comment中，我用AdView实现了一个协调器，它成功了

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)")}
        }
    }
}

使用

协调器

作为

gadbanerviewdelegate

并在其中移动那些回调函数。

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)")}
        }
    }
}
