Admob Rewarded video - Root view controller issue - ios

Question

So I have two view controllers in my application:
StartViewController (Root view controller) and GameViewController
I am presenting my Rewarded video from GameViewController
Everything works perfectly, except for when the user presses "Skip now" on the rewarded video. It dismisses GameViewController and goes back to StartViewController which is my root view controller.
If the user watches the entire video, it works as intended.
The code for presenting rewarded view from GameViewController:
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)
}
}
}
I temporarily changed the root to GameViewController to see if this was the issue and doing so fixed it, so I know it is an issue related to the root view controller and the "Skip now" button on the rewarded video.

I had the same issue. I solved it by overriding the func dismiss(animated flag: Bool, completion: (() -> Void)? = nil method.
Here is what I did.
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)
}
Before showing the rewardedAd, do not forget to check if it's ready or not.
GADRewardBasedVideoAd.sharedInstance().isReady == true
When rewardedAd is presented didOpenRewardedVideo is set to 1. When user dismissing rewardedAd didOpenRewardedVideo is 1 and calling super.dismiss(animated: flag, completion: completion). Then didOpenRewardedVideo is set to 2. Now I know dismiss(animated flag: Bool, completion: (() -> Void)? = nil) will be called once more. This time I don't call the super method and set didOpenRewardedVideo to 0. I know if I dismiss my UIViewController will be dismissed.

#mialkan,
your solution does not work. I don't why no one talk about this issue. I am also facing such problem.

Answer 3

import GoogleMobileAds import sdk in your class or viewcontroller
GADRewardBasedVideoAdDelegate Add this in your class or viewcontroller
var RewardBasedVideo: GADRewardBasedVideoAd? **initialize AdController object **
override func viewDidLoad()
{
super.viewDidLoad()
RewardBasedVideo=GADRewardBasedVideoAd.sharedInstance()
RewardBasedVideo?.delegate = self
}
//MARK:- WATCH AD BUTTON CLICK
#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.")
}

For those of you who is facing the the same issue:
You can create a new class for your rootViewController (TabBarController or NavigationController etc.) and implement there something like that:
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
Important! Use this functions inside TabBarController or NavigationController, otherwise it is not gonna work
UPD:
In my case unfortunatly it breaks all NavigationControllers inside a TabBarController (titles don't show and there are no buttons inside them), if I will figure fix actions, I'll let you know
UPD2:
Pretty obvious decision will be to change the initialViewController and view add from it, it'll not be dismissed
UPD3:
I solved this very and very strange:
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
}
}
