import UIKit
import GoogleMobileAds

class ViewController: UIViewController {

    var bannerView: GADBannerView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // 创建广告实例
        bannerView = GADBannerView(adSize: kGADAdSizeBanner)
        bannerView.adUnitID = "YOUR_AD_UNIT_ID"
        bannerView.rootViewController = self

        // 创建广告容器
        let adContainerView = UIView()
        adContainerView.frame = CGRect(x: 0, y: 0, width: view.frame.size.width, height: bannerView.frame.size.height)

        // 将广告容器添加到tableView的底部
        tableView.tableFooterView = adContainerView

        // 将广告添加到广告容器中
        adContainerView.addSubview(bannerView)

        // 请求加载广告
        let request = GADRequest()
        bannerView.load(request)
    }
