如何将 AdMob GADBannerView 添加到每个视图

我正在我的应用程序中实现一个 AdMob 横幅UIViewController，并且它正在工作。但我有很多视图，我想在每个屏幕上显示一个横幅。我如何实现一个出现在每个屏幕上的横幅？我正在尝试这个AppDelegate.swift:

dispatch_async(dispatch_get_main_queue(), {
    print("Google Mobile Ads SDK version: \(GADRequest.sdkVersion())")
    // bannerView.frame = CGRectMake(0, 0, 320, 50)
    // self.bannerView.adSize = kGADAdSizeBanner
    self.bannerView.adUnitID = "ca-app-pub-MY_ID"
    bannerView.rootViewController = self.window
    self.bannerView.loadRequest(GADRequest())
    self.window?.addSubview(self.bannerView)
})

但它不起作用

创建共享横幅。你init它在你的AppDelegate然后将其添加到UIViewController您希望在其上放置横幅：

class AppDelegate: UIResponder, UIApplicationDelegate, GADBannerViewDelegate {

var window: UIWindow?
var adBannerView = GADBannerView()

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    adBannerView.adUnitID = "YourAdUnitID"
    adBannerView.delegate = self
    adBannerView.load(GADRequest())
    adBannerView.isHidden = true

    return true
}

func adViewDidReceiveAd(_ bannerView: GADBannerView!) {
    adBannerView.isHidden = false
}
func adView(_ bannerView: GADBannerView!, didFailToReceiveAdWithError error: GADRequestError!) {
    adBannerView.isHidden = true
}

In each UIViewController你想要一个横幅：

let appDelegate = UIApplication.shared.delegate as! AppDelegate

override func viewDidLoad() {
    super.viewDidLoad()
    addBannerToView()
}

func addBannerToView() {
    appDelegate.adBannerView.adSize = kGADAdSizeBanner
    appDelegate.adBannerView.rootViewController = self
    appDelegate.adBannerView.frame = CGRect(x: 0.0,
                      y: view.frame.height - appDelegate.adBannerView.frame.height,
                      width: view.frame.width,
                      height: appDelegate.adBannerView.frame.height)
    view.addSubview(appDelegate.adBannerView)
}
