ios - View 层次结构中的 GADInterstitial 重复项

Question

我有一个 GADInterstitial 的实现

class AdsManager {

    let adsAppId = MY_ID
    let fullScreenAdUnitId = MY_ID

    static let manager: AdsManager = AdsManager()

    private var interstitial: GADInterstitial!

    private init () {
        createAndLoadInterstitial()
    }

    func presentInterstitial(fromViewController viewController: UIViewController) {
        if interstitial.isReady {
            interstitial.present(fromRootViewController: viewController)
        }
        else {
            print("Interstitial is not ready")
        }

        createAndLoadInterstitial()
    }

    private func createAndLoadInterstitial() {
        //TODO: replace test ad unit id with production
        interstitial = GADInterstitial(adUnitID: MY_ID)
        interstitial.load(GADRequest())
    }
}

我这样展示这个广告:

func touchedButton(_ sender: UIButton) {
    AdsManager.manager.presentInterstitial(fromViewController: self)
}

Everythink 工作并且看起来不错，但是当我调试时，我发现了一些奇怪的东西:



同一 View 的四个实例。有谁知道好用吗？或者，也许我在 AdsManager 中犯了一个错误。 ?也许 Firebase 实现错误？

数量GADUIKitWebView的取决于所呈现的广告类型。视频、图片和文字广告都有不同的布局。根据使用的内存量，我认为它是正确的。

除此之外，您的实现确实存在问题。您的问题出在此功能中:

func presentInterstitial(fromViewController viewController: UIViewController) {
    if interstitial.isReady {
        interstitial.present(fromRootViewController: viewController)
    }
    else {
        print("Interstitial is not ready")
    }

    createAndLoadInterstitial() // PROBLEM
}

你应该移动 createAndLoadInterstitial()进入 else所以你只加载另一个 GADInterstitial当你真正需要的时候。例如:

func presentInterstitial(fromViewController viewController: UIViewController) {
    if interstitial.isReady {
        interstitial.present(fromRootViewController: viewController)
    }
    else {
        print("Interstitial is not ready")
        createAndLoadInterstitial()
    } 
}

除此之外，您应该实现 GADInterstitial delegate methods并加载另一个 GADInterstitial只有在它关闭屏幕后。例如:

/// Called just after dismissing an interstitial and it has animated off the screen.
func interstitialDidDismissScreen(_ ad: GADInterstitial) {
    print("interstitialDidDismissScreen")
    createAndLoadInterstitial()
}
