# Implementation of rewarded video

• Ad Manager

  By using the UnitID that set mediation on GoogleAdManager management screen, you can display the mediated RewardedVideo ads.
  For details on how to implement the RewardedVideo, please refer to the following site.
  How to implement RewardedVideo of GoogleAdManager

• AdMob

  By using the UnitID that set mediation on GoogleAdMob management screen, you can display the mediated RewardedVideo ads.
  For details on how to implement the RewardedVideo, please refer to the following site.
  How to implement RewardedVideo of AdMob

# Preparation for implementation

Import GoogleMobileAds.

• ObjectiveC
  Import GoogleMobileAds and add Delegate.

例：ViewController.m

@import GoogleMobileAds;

@interface RewardNewViewController () <GADFullScreenContentDelegate>

• Swift
  Nothing in particular.

# Implement Delegate for ad display

Implement the GADFullScreenContentDelegate method to receive notifications from the SDK.

• ObjectiveC

/// Tells the delegate that the rewarded ad was presented.
- (void)adDidPresentFullScreenContent:(id)ad {
}

/// Tells the delegate that the rewarded ad failed to present.
- (void)ad:(id)ad　didFailToPresentFullScreenContentWithError:(NSError *)error {
}

/// Tells the delegate that the rewarded ad was dismissed.
- (void)adDidDismissFullScreenContent:(id)ad {
}

• Swift

extension ViewController : GADFullScreenContentDelegate {

    /// Tells the delegate that the rewarded ad was presented.
    func adDidPresentFullScreenContent(_ ad: GADFullScreenPresentingAd) {
    }

    /// Tells the delegate that the rewarded ad was dismissed.
    func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
    }

    /// Tells the delegate that the rewarded ad failed to present.
    func ad(_ ad: GADFullScreenPresentingAd, didFailToPresentFullScreenContentWithError error: Error) {
    }
}

# Load rewarded video ad

Implement the ad loading process. We recommend that you perform the loading process in advance. In the load request, specify the UnitID. (Get UnitId from the management screen of Google AdMob / Ad Manager)

If you want to show another video after playing one video, you need to make a load request again.

• ObjectiveC

@property(nonatomic, strong) GADRewardedAd *rewardedAd;

- (void)loadReward {
    GAMRequest *request = [GAMRequest request];
    [GADRewardedAd loadWithAdUnitID:@"YOUR_UNIT_ID" request:request completionHandler:^(GADRewardedAd *ad, NSError *error) {
        if (error) {
            return;
        }
        self.rewardedAd = ad;
        self.rewardedAd.fullScreenContentDelegate = self;
    }];
}

• Swift

var rewardedAd: GADRewardedAd!

func loadReward() {
    let request = GAMRequest()
    GADRewardedAd.load(withAdUnitID: "YOUR_UNIT_ID", request: request, completionHandler: { (ad, error) in
        if let error = error {
            return
        }
        self.rewardedAd = ad
        self.rewardedAd?.fullScreenContentDelegate = self
    })
}

# Display rewarded video

Implement the display process of the advertisement. Please execute the display process after executing Load.

• ObjectiveC

- (void)showReward {
    if (self.rewardedAd) {
        [self.rewardedAd presentFromRootViewController:self userDidEarnRewardHandler:^ {
            GADAdReward *reward = self.rewardedAd.adReward;
            // TODO: Reward the user.
            NSLog(@"rewardedAd:userDidEarnRewardHandler %@, amount %lf", reward.type, [reward.amount doubleValue]);
        }];
    }
}

• Swift

func showReward() {
    if let ad = rewardedAd {
        ad.present(fromRootViewController: self, userDidEarnRewardHandler: {
            let reward = ad.adReward
            // TODO: Reward the user.
            print("rewardedAd:userDidEarnRewardHandler \(reward.type), amount \(reward.amount).")
        })
    }
}

# Give users a reward

To maximize revenue with video ads, it is important to remunerate video ad viewers.
GADAdReward includes the following items.

• reward.type：Currency type setting
• reward.amount：Currency amount setting

To reward video ad viewers, use the callback method userDidEarnRewardHandler of the display processpresentFromRootViewController.
