Rewarded Video Ads (Legacy API)

Rewarded video ads are full-screen video ads that users have the option of watching in full in exchange for in-app rewards.

This guide shows you how to integrate rewarded video ads from AdMob into an iOS app.

Prerequisites

Request rewarded video

GADRewardBasedVideoAd has a singleton design, so the following example shows a request to load an ad being made to the shared instance:

Swift

GADRewardBasedVideoAd.sharedInstance().load(GADRequest(),
    withAdUnitID: "ca-app-pub-3940256099942544/1712485313")

Objective-C

[[GADRewardBasedVideoAd sharedInstance] loadRequest:[GADRequest request]
    withAdUnitID:@"ca-app-pub-3940256099942544/1712485313"];

To allow videos to be preloaded, we recommend making your load request call as early as possible (for example, in your app delegate's application:didFinishLaunchingWithOptions: method).

Always test with test ads

When building and testing your apps, make sure you use test ads rather than live, production ads. Failure to do so can lead to suspension of your account.

The easiest way to load test ads is to use our dedicated test ad unit ID for iOS rewarded video:

ca-app-pub-3940256099942544/1712485313

It's been specially configured to return test ads for every request, and you're free to use it in your own apps while coding, testing, and debugging. Just make sure you replace it with your own ad unit ID before publishing your app.

For more information about how the Mobile Ads SDK's test ads work, see Test Ads.

Set up event notifications

To set up event notification, insert the line shown in bold before your load request call:

Swift

GADRewardBasedVideoAd.sharedInstance().delegate = self
GADRewardBasedVideoAd.sharedInstance().load(GADRequest(),
    withAdUnitID: "ca-app-pub-3940256099942544/1712485313")

Objective-C

[GADRewardBasedVideoAd sharedInstance].delegate = self;
[[GADRewardBasedVideoAd sharedInstance] loadRequest:[GADRequest request]
                                       withAdUnitID:@"ca-app-pub-3940256099942544/1712485313"];

GADRewardBasedVideoAdDelegate notifies you of rewarded video lifecycle events. You are required to set the delegate prior to loading an ad. The most important event in this delegate is rewardBasedVideoAd:didRewardUserWithReward:, which is called when the user should be rewarded for watching a video. You may optionally implement other methods in this delegate.

The following sample illustrates how to log each of the events available in GADRewardBasedVideoAdDelegate:.

Swift

func rewardBasedVideoAd(_ rewardBasedVideoAd: GADRewardBasedVideoAd,
    didRewardUserWith reward: GADAdReward) {
  print("Reward received with currency: \(reward.type), amount \(reward.amount).")
}

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

func rewardBasedVideoAdDidOpen(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
  print("Opened reward based video ad.")
}

func rewardBasedVideoAdDidStartPlaying(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
  print("Reward based video ad started playing.")
}

func rewardBasedVideoAdDidCompletePlaying(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
  print("Reward based video ad has completed.")
}

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

func rewardBasedVideoAdWillLeaveApplication(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
  print("Reward based video ad will leave application.")
}

func rewardBasedVideoAd(_ rewardBasedVideoAd: GADRewardBasedVideoAd,
    didFailToLoadWithError error: Error) {
  print("Reward based video ad failed to load.")
}

Objective-C

- (void)rewardBasedVideoAd:(GADRewardBasedVideoAd *)rewardBasedVideoAd
    didRewardUserWithReward:(GADAdReward *)reward {
  NSString *rewardMessage =
      [NSString stringWithFormat:@"Reward received with currency %@ , amount %lf",
          reward.type,
          [reward.amount doubleValue]];
  NSLog(rewardMessage);
}

- (void)rewardBasedVideoAdDidReceiveAd:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Reward based video ad is received.");
}

- (void)rewardBasedVideoAdDidOpen:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Opened reward based video ad.");
}

- (void)rewardBasedVideoAdDidStartPlaying:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Reward based video ad started playing.");
}

- (void)rewardBasedVideoAdDidCompletePlaying:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Reward based video ad has completed.");
}

- (void)rewardBasedVideoAdDidClose:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Reward based video ad is closed.");
}

- (void)rewardBasedVideoAdWillLeaveApplication:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Reward based video ad will leave application.");
}

- (void)rewardBasedVideoAd:(GADRewardBasedVideoAd *)rewardBasedVideoAd
    didFailToLoadWithError:(NSError *)error {
  NSLog(@"Reward based video ad failed to load.");
}

Display rewarded video

It is a best practice to ensure that a rewarded video ad has completed loading before attempting to display it. The isReady method indicates that a rewarded video ad request has been successfully fulfilled:

Swift

if GADRewardBasedVideoAd.sharedInstance().isReady == true {
  GADRewardBasedVideoAd.sharedInstance().present(fromRootViewController: self)
}

Objective-C

if ([[GADRewardBasedVideoAd sharedInstance] isReady]) {
  [[GADRewardBasedVideoAd sharedInstance] presentFromRootViewController:self];
}

Reload a rewarded video

A handy place to load a new rewarded video ad after the previous one is in rewardBasedVideoAdDidClose:.

Swift

func rewardBasedVideoAdDidClose(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
  GADRewardBasedVideoAd.sharedInstance().load(GADRequest(),
      withAdUnitID: "ca-app-pub-3940256099942544/1712485313")
}

Objective-C

- (void)rewardBasedVideoAdDidClose:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  [[GADRewardBasedVideoAd sharedInstance] loadRequest:[GADRequest request]
           withAdUnitID:@"ca-app-pub-3940256099942544/1712485313"];
}
