Question

所以我的应用程序中有两个视图控制器：

StartViewController (Root view controller)和GameViewController

我正在展示我的GameViewController奖励视频

除了用户在奖励视频上按“立即跳过”时，所有其他操作均正常。它关闭GameViewController并返回到我的根视图控制器StartViewController。

如果用户观看了整个视频，则视频可以正常播放。

用于显示来自GameViewController的奖励视图的代码：

func playReward()
{
    if rewardVideo!.isReady
    {
        if var topController = UIApplication.shared.keyWindow?.rootViewController
        {
            while let presentedViewController = topController.presentedViewController
            {
                // Make top controller topmost view controller
                topController = presentedViewController
            }

            rewardVideo!.present(fromRootViewController: topController)
        }
    }
}

我暂时将根更改为GameViewController，以查看是否是问题所在，并进行了修复，因此我知道这是与根视图控制器和奖励上的“立即跳过”按钮有关的问题视频。

我有同样的问题。我通过重写func dismiss(animated flag: Bool, completion: (() -> Void)? = nil方法解决了这个问题。

这就是我所做的。

var didOpenRewardedVideo:Int = 0 
override func dismiss(animated flag: Bool, completion: (() -> Void)? = nil) {
    if didOpenRewardedVideo == 1 {
        didOpenRewardedVideo = 2
        super.dismiss(animated: flag, completion: completion)
    }
    else if didOpenRewardedVideo == 2{
        didOpenRewardedVideo = 0
    }
    else{
        super.dismiss(animated: flag, completion: completion)
    }
}
func showRewardedVideo()
{
    didOpenRewardedVideo = 1
    GADRewardBasedVideoAd.sharedInstance().present(fromRootViewController: self)
}

在显示奖励广告之前，请不要忘记检查广告是否已准备好。

GADRewardBasedVideoAd.sharedInstance().isReady == true

当出现rewardedAd时，didOpenRewardedVideo设置为1。当用户关闭rewardedAd时，didOpenRewardedVideo为1，然后调用super.dismiss(animated: flag, completion: completion)。然后将didOpenRewardedVideo设置为2。现在我知道dismiss(animated flag: Bool, completion: (() -> Void)? = nil)将再次被调用。这次我不调用super方法并将didOpenRewardedVideo设置为0。我知道如果我解雇了UIViewController，我将被解雇。

@mialkan，

您的解决方案不起作用。我不为什么没有人谈论这个问题。我也面临这样的问题。

Answer 3

导入GoogleMobileAds 导入类或ViewController中的SDK

GADRewardBasedVideoAdDelegate 将此添加到您的类或ViewController中

var RewardBasedVideo：GADRewardBasedVideoAd？ **初始化AdController对象**

override func viewDidLoad()
{
    super.viewDidLoad()
    RewardBasedVideo=GADRewardBasedVideoAd.sharedInstance()
    RewardBasedVideo?.delegate = self
}

// MARK：-观看广告按钮点击

 @IBAction func WatchAdBtn_Click(_ sender: UIButton)
 {
    if RewardBasedVideo?.isReady == true
     {
        RewardBasedVideo?.present(fromRootViewController: self)
    } else
     {
     //Show alert here "Ads is not ready to load"
    }
}

func rewardBasedVideoAdDidClose(_ rewardBasedVideoAd: GADRewardBasedVideoAd) 
{
    print("Reward based video ad is closed.")
}

对于那些面临相同问题的人：

您可以为rootViewController（TabBarController或NavigationController等）创建一个新类，并在其中实现类似的内容：

override func dismiss(animated flag: Bool, completion: (() -> Void)? = nil) {
    dismissalCounter += 1
    if (dismissalCounter < 2) {
       super.dismiss(animated: flag, completion: completion)
    }
}

override func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {
    dismissalCounter = 0
}

override func present(_ viewControllerToPresent: UIViewController, animated flag: Bool, completion: (() -> Void)? = nil) {
    dismissalCounter = 0
    super.present(viewControllerToPresent, animated: flag, completion: completion)
}

var dismissalCounter : Int = 0

重要！在TabBarController或NavigationController中使用此功能，否则将无法正常工作

UPD： 对于我而言，很不幸，它会破坏TabBarController内的所有NavigationController（标题没有显示，并且里面没有按钮），如果我想解决问题的话，我会告诉你

UPD2： 显而易见的决定是更改initialViewController并从中查看添加内容，不会被删除

UPD3： 我解决了这个非常非常奇怪的问题：

class ViewController : UIViewController {  
override func viewWillAppear(_ animated: Bool) {
        if GADRewardBasedVideoAd.sharedInstance().isReady == false {
             let request = GADRequest()
            rewardBasedVideo!.load(request, withAdUnitID: "ca-app-pub-3940256099942544/1712485313")
        }
    }

    var rewardBasedVideo: GADRewardBasedVideoAd?

    @IBAction func ad_button_click(_ sender: Any) {
        if rewardBasedVideo!.isReady == true     {
            let bl = blur()
            self.present(bl, animated: true, completion: {
                self.rewardBasedVideo?.present(fromRootViewController: bl)
            })

        }
    }

}

class blur : UIViewController {
    override func viewDidLoad() {
        checkForKeyWindow()
    }

    func checkForKeyWindow() {
        DispatchQueue.main.asyncAfter(deadline: .now() + 2, execute: {
            if (UIApplication.topViewController() == self) {
                print("dismissed and forgotten")
                self.dismiss(animated: true, completion: nil)
            } else {
                print("not keywindow")
                self.checkForKeyWindow()
            }
        })
    }

    @objc func close() {
       self.dismiss(animated: true, completion: nil)
    }
}

extension UIApplication {
    class func topViewController(base: UIViewController? = UIApplication.shared.keyWindow?.rootViewController) -> UIViewController? {

        if let nav = base as? UINavigationController {
            return topViewController(base: nav.visibleViewController)
        }

        if let tab = base as? UITabBarController {
            let moreNavigationController = tab.moreNavigationController

            if let top = moreNavigationController.topViewController, top.view.window != nil {
                return topViewController(base: top)
            } else if let selected = tab.selectedViewController {
                return topViewController(base: selected)
            }
        }

        if let presented = base?.presentedViewController {
            return topViewController(base: presented)
        }

        return base
    }
}
