Question

我希望在多个视图控制器（包括但不限于UITabBarController）中加载 Google Admob Banner View的一个实例。

我的尝试如下。我正在使用AppDelegate设置adSize，adUnitID和testDevices。然后在每个想要显示横幅的VC中，我设置了rootViewController，frame，load request，然后是addSubView。

这很有效，因为广告显示得很好。但是，当我提出或解雇VC时，广告会不断变化！每当VC改变时，似乎都会发生新的请求。 这正是必须避免的结果！

的AppDelegate

class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
    var adBannerViewFromAppDelegate = GADBannerView()
    let loadRequest = GADRequest()

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    adBannerViewFromAppDelegate.adSize = kGADAdSizeSmartBannerPortrait
    adBannerViewFromAppDelegate.adUnitID = "12345"
    loadRequest.testDevices = [kGADSimulatorID, myiPhone]
    }
}

的ViewController （这有一个通过Push Segue的SecondViewController按钮）

import UIKit
import GoogleMobileAds

class ViewController: UIViewController {

    let appDelegate = UIApplication.shared.delegate as! AppDelegate

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

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        addBannerToView()
    }

    func addBannerToView() {
        appDelegate.adBannerViewFromAppDelegate.rootViewController = self
        appDelegate.adBannerViewFromAppDelegate.load(appDelegate.loadRequest)
        appDelegate.adBannerViewFromAppDelegate.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: appDelegate.adBannerViewFromAppDelegate.frame.height)
        view.addSubview(appDelegate.adBannerViewFromAppDelegate)
    }

}

SecondViewController

import UIKit
import GoogleMobileAds

class SecondViewController: UIViewController {

    let appDelegate = UIApplication.shared.delegate as! AppDelegate

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

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        addBannerToView()
    }

    @IBAction func closeButtonPressed(_ sender: UIButton) {
        self.dismiss(animated: true, completion: nil)
    }

    func addBannerToView() {
        appDelegate.adBannerViewFromAppDelegate.rootViewController = self
        appDelegate.adBannerViewFromAppDelegate.load(appDelegate.loadRequest)
        appDelegate.adBannerViewFromAppDelegate.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: appDelegate.adBannerViewFromAppDelegate.frame.height)
        view.addSubview(appDelegate.adBannerViewFromAppDelegate)
    }

}

如何在AppDelegate中创建的一个横幅实例显示在多个 ViewControllers上？感谢。
