AdMob显示测试广告，但不是真正的广告Swift / SwiftUI

import SwiftUI
import GoogleMobileAds

struct ContentView: View {
    var body: some View {
        VStack {
            Text("Your Content Here")
                .padding()
            
            AdBannerView()
                .frame(width: 320, height: 50) // 设置广告横幅的大小
            
            Spacer()
        }
    }
}

struct AdBannerView: UIViewRepresentable {
    func makeUIView(context: Context) -> GADBannerView {
        let bannerView = GADBannerView(adSize: kGADAdSizeBanner) // 创建广告横幅实例
        bannerView.adUnitID = "YOUR_TEST_AD_UNIT_ID" // 使用测试广告单元ID
        bannerView.rootViewController = UIApplication.shared.windows.first?.rootViewController
        bannerView.load(GADRequest()) // 加载广告
        return bannerView
    }

        // 更新视图
    }
