SWIFTUIADMOB-负载失败的隐藏建议

Question

struct BottomBannerView : View {
    
    @State var isLoaded: Bool = true
    
    var body : some View{
        AdViewBottom(isLoaded: self.$isLoaded)
            .frame(width: 320, height: isLoaded ? 50 : 0)
    }
}

struct AdViewBottom: UIViewRepresentable {
    
    @Binding var isLoaded: Bool
    
    class Coordinator: NSObject, GADBannerViewDelegate {
        func bannerView(_ bannerView: GADBannerView, didFailToReceiveAdWithError error: Error) {
            print("Ad failed to load: \(error.localizedDescription)")
            isLoaded = false // HOW???
        }
    }

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

    func makeUIView(context: Context) -> GADBannerView {
        let banner = GADBannerView(adSize: GADAdSizeBanner)
        banner.adUnitID = "ca-app-pub-xxx~xxxx"
        // banner.rootViewController = UIApplication.shared.windows.first?.rootViewController // The root view controller is needed to present full screen content.
        banner.delegate = context.coordinator
        banner.load(GADRequest())
        banner.backgroundColor = .black
        return banner
    }

    // SwiftUI calls this method to update the GADBannerView.
    func updateUIView(_ uiView: GADBannerView, context: Context) {
        // In this case, no update is needed.
    }
}
