仅在特定场景中显示 adMob 横幅；迅速

Question

在我的游戏中，我有 4 个不同的场景。现在我想在这 4 个场景中的 2 个中投放一些 AdMob 横幅广告。

我是这样试的。

class GameViewController: UIViewController, GADBannerViewDelegate {


var bannerView: GADBannerView!



override func viewDidLoad() {

    super.viewDidLoad()


    if let view = self.view as! SKView? {
        // Load the SKScene from 'GameScene.sks'

        if var scene = StartScene(fileNamed: "StartScene") {





            // Set the scale mode to scale to fit the window
            scene.scaleMode = .aspectFill

            // Present the scene
            view.presentScene(scene)



        }



        if var scene = MainMenuScene(fileNamed: "MainMenuScene") {



        bannerView = GADBannerView(adSize: kGADAdSizeBanner)

        self.view.addSubview(bannerView)
        let request = GADRequest()
        request.testDevices = [kGADSimulatorID]
        bannerView.rootViewController = self
        bannerView.delegate = self
        bannerView.adUnitID = "ca-app-pub-2567181742111069/9977523039"
        bannerView.load(request)
        bannerView.center = CGPoint(x: 329, y: 350)

        }


        view.ignoresSiblingOrder = true

        view.showsPhysics = false


        view.showsFPS = false
        view.showsNodeCount = false



      }



}

问题是，广告仍然显示在每个场景中。

有谁知道如何解决这个问题？

Answer 1

广告会在每个场景中显示，因为横幅视图附加到包含子场景的 GameViewController（充当超级视图）。

创建并加载横幅广告viewDidLoad()并将其隐藏在您不希望它出现的场景中，然后在您想要的场景中显示它：

class GameViewController: UIViewController, GADBannerViewDelegate {


var bannerView: GADBannerView!



override func viewDidLoad() {

    super.viewDidLoad()

        bannerView = GADBannerView(adSize: kGADAdSizeBanner)

        self.view.addSubview(bannerView)
        let request = GADRequest()
        request.testDevices = [kGADSimulatorID]
        bannerView.rootViewController = self
        bannerView.delegate = self
        bannerView.adUnitID = "ca-app-pub-2567181742111069/9977523039"
        bannerView.load(request)
        bannerView.center = CGPoint(x: 329, y: 350)


    if let view = self.view as! SKView? {
        // Load the SKScene from 'GameScene.sks'

        if var scene = StartScene(fileNamed: "StartScene") {

            // Set the scale mode to scale to fit the window
            scene.scaleMode = .aspectFill

            // Present the scene
            self.bannerView.isHidden = true
            view.presentScene(scene)
        }



        if var scene = MainMenuScene(fileNamed: "MainMenuScene") {

                self.bannerView.isHidden = false

        }


        view.ignoresSiblingOrder = true

        view.showsPhysics = false


        view.showsFPS = false
        view.showsNodeCount = false



      }

}

您还可以使用addSubView和removeFromSuperview函数从超级视图（GameViewController）及其窗口中添加/删除
