如何使用 AdMob 横幅摆脱消息“'windows' 在 iOS 15.0 中已弃用：在相关窗口场景上使用 UIWindowScene.windows”？

Question

我想在我的函数中删除“'windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a related window scene instead”消息（顺便说一句，我的函数运行良好。）。

涉及的代码行：

banner.rootViewController = UIApplication.shared.windows.first?.rootViewController

我该怎么做？

我的功能：

struct AdView : UIViewRepresentable {
    func makeUIView(context: UIViewRepresentableContext<AdView>) -> GADBannerView {
        let banner = GADBannerView(adSize: kGADAdSizeBanner)
        banner.adUnitID = "ca-app-pub-3940256099942544/2934735716" // test ad
                banner.rootViewController = UIApplication.shared.windows.first?.rootViewController
        banner.load(GADRequest())
        return banner
    }
    
    func updateUIView(_ uiView: GADBannerView, context: UIViewRepresentableContext<AdView>) {}
}

我试过了，但它不起作用：

banner.rootViewController = UIApplication.shared.connectedScenes.first?.rootViewController

谢谢

您可以使用以下UIApplication.shared.currentUIWindow()?.rootViewController

public extension UIApplication {
    func currentUIWindow() -> UIWindow? {
        let connectedScenes = UIApplication.shared.connectedScenes
            .filter({
                $0.activationState == .foregroundActive})
            .compactMap({$0 as? UIWindowScene})
        
        let window = connectedScenes.first?
            .windows
            .first { $0.isKeyWindow }

        return window
        
    }
}
