Pollfish iOS AdMob Mediation Adapter

AdMob Mediation Adapter for iOS apps looking to load and show Rewarded Surveys from Pollfish in the same waterfall with other Rewarded Ads.

Note: A detailed step by step guide is provided on how to integrate can be found here

Step 1: Add Pollfish AdMob Adapter to your project

Download the following frameworks

• Pollfish SDK
• PollfishAdMobAdapter

and add them in your App's target dependecies

1. Navigate to your project
2. Select your App's target and go to the General tab section Frameworks, Libraries and Embedded Content
3. Add all dependent framewokrs one by one by pressing the + button -> Add other and selecting the appropriate framework

Add the following frameworks (if you don’t already have them) in your project

• AdSupport.framework
• CoreTelephony.framework
• SystemConfiguration.framework
• WebKit.framework (added in Pollfish v4.4.0)

OR

Retrieve Pollfish AdMob Adapter through CocoaPods

Add a Podfile with Pollfish framework as a pod reference:

pod 'PollfishAdMobAdapter'

You can find latest Pollfish iOS SDK version on CocoaPods here

Run pod install on the command line to install Pollfish cocoapod.

Step 2: Request for a RewardedAd

Import GoogleMobileAds

Swift

import GoogleMobileAds

Objective C

@import GoogleMobileAds;

Initialize the SDK in your app delegate’s application:applicationDidFinishLaunching: method

Swift

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

    GADMobileAds.sharedInstance().start()
    
    return true
}

Objective C

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [[GADMobileAds sharedInstance] startWithCompletionHandler:nil];
    return YES;
}

Implement GoogleMobileAds so that you are notified when your ad is ready and of other ad-related events.

Request a GADRewardedAd from AdMob by calling load in the GADRewardedAd object passing a GADRequest instance and your AD_UNIT_ID id. By default Pollfish AdMob Adapter will use the configuration as provided on AdMob's dashboard. If no configuration is provided or if you want to override any of those params please see step 3.

Swift

class ViewController: UIViewController, GADFullScreenContentDelegate {

    var rewardedAd: GADRewardedAd?

    ...

    func createRewardedAd() {
        let request = GADRequest()

        GADRewardedAd.load(withAdUnitID: "AD_UNIT_ID",
                           request: request) { (ad, error) in

            guard let error = error else {
                print("Failed to load ad with error: \(error!.localizedDescription)")
                return
            }
            
            self.rewardedAd = ad
            self.rewardedAd?.fullScreenContentDelegate = self
        }
    }

    func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {}
    
    func ad(_ ad: GADFullScreenPresentingAd, didFailToPresentFullScreenContentWithError error: Error) {}
    
    func adDidPresentFullScreenContent(_ ad: GADFullScreenPresentingAd) {}

}

Objective C

@interface ViewController()<GADFullScreenContentDelegate>
@property(nonatomic, strong) GADRewardedAd *rewardedAd;
@end

@implementation ViewController

...

- (void)createRewardedAd
{
    GADRequest *request = [GADRequest request];

    [GADRewardedAd loadWithAdUnitID:@"AD_UNIT_ID" request:request completionHandler:^(GADRewardedAd *ad, NSError *error) {
        if (error) {
            NSLog(@"Failed to load interstitial ad with error: %@", [error localizedDescription]);
            return;
        }
        
        self.rewardedAd = ad;
        self.rewardedAd.fullScreenContentDelegate = self;
    }];
}

#pragma mark - GADFullScreenContentDelegate Protocol

- (void)adDidPresentFullScreenContent:(id)ad {}

- (void)ad:(id)ad didFailToPresentFullScreenContentWithError:(NSError *)error {}

- (void)adDidDismissFullScreenContent:(id)ad {}

@end

When the Rewarded Ad is ready, present the ad by invoking rewardedAd.present which accepts a ViewController and a reward completion block. Just to be sure, you can combine present with a nullity check to see if the Ad you are about to show is actualy ready.

Swift

if (rewardedAd != nil) {
    rewardedAd?.present(fromRootViewController: self) {
        let reward = self.rewardedAd!.adReward
        print("Reward received with currency \(reward.type), amount \(reward.amount)")
    }
} 

Objective C

if (self.rewardedAd) {
    [self.rewardedAd presentFromRootViewController:self userDidEarnRewardHandler:^(void) {
        GADAdReward *reward = self.rewardedAd.adReward;
        NSString *rewardMessage = [NSString stringWithFormat:@"Reward received with currency %@, amount %lf", reward.type, [reward.amount doubleValue]];
        NSLog(@"%@", rewardMessage);
    }];
} 

Step 3: Use and control Pollfish AdMob Adapter in your Rewarded Ad Unit (Optional)

Pollfish AdMob Adapter provides different options that you can use to control the behaviour of Pollfish SDK. This configuration, if applied, will override any configuration done in AdMob's dashboard.

Below you can see all the available options of GADPollfishRewardedNetworkExtras instance that is used to configure the behaviour of Pollfish SDK.

3.1 .pollfishAPIKey

Pollfish API Key as provided by Pollfish on Pollfish Dashboard after you sign up to the platform. If you have already specified Pollfish API Key on AdMob's UI, this param will be ignored.

3.2 .requestUUID

Sets a unique id to identify a user and be passed through server-to-server callbacks on survey completion.

In order to register for such callbacks you can set up your server URL on your app's page on Pollfish Developer Dashboard and then pass your requestUUID through ParamsBuilder object during initialization. On each survey completion you will receive a callback to your server including the requestUUID param passed.

If you would like to read more on Pollfish s2s callbacks you can read the documentation here

3.3 .releaseMode

Sets Pollfish SDK to Developer or Release mode.

• Developer mode is used to show to the developer how Pollfish surveys will be shown through an app (useful during development and testing).
• Release mode is the mode to be used for a released app in any app store (start receiving paid surveys).

Pollfish AdMob Adapter runs Pollfish SDK in release mode by default. If you would like to test with Test survey, you should set release mode to fasle.

3.4 .offerwallMode

Enables offerwall mode. If not set, one single survey is shown each time.

Below you can see an example on how you can use GADPollfishRewardedNetworkExtras to pass info to Pollfish AdMob Adapter:

Swift

import PollfishAdMobAdapter

...

let request = GADRequest()
        
let pollfishNetworkExtras = GADPollfishRewardedNetworkExtras()
pollfishNetworkExtras.pollfishAPIKey = "POLLFISH_API_KEY"
pollfishNetworkExtras.releaseMode = false
pollfishNetworkExtras.requestUUID = "USER_ID"
pollfishNetworkExtras.offerwallMode = false

request.register(pollfishNetworkExtras)

Objective C

#import <PollfishAdMobAdapter/GADPollfishRewardedNetworkExtras.h>

...

GADRequest *request = [GADRequest request];
    
GADPollfishRewardedNetworkExtras *pollfishNetworkExtras = [[GADPollfishRewardedNetworkExtras alloc] init];
    
pollfishNetworkExtras.pollfishAPIKey = @"POLLFISH_API_KEY";
pollfishNetworkExtras.releaseMode = false;
pollfishNetworkExtras.requestUUID = @"YOUR_USER_ID";
pollfishNetworkExtras.offerwallMode = false;
    
[request registerAdNetworkExtras:pollfishNetworkExtras];

Step 4: Publish your app on the store

If you everything worked fine during the previous steps, you should turn Pollfish to release mode and publish your app.

Note: After you take your app live, you should request your account to get verified through Pollfish Dashboard in the App Settings area.

Note: There is an option to show Standalone Demographic Questions needed for Pollfish to target users with surveys even when no actually surveys are available. Those surveys do not deliver any revenue to the publisher (but they can increase fill rate) and therefore if you do not want to show such surveys in the Waterfall you should visit your App Settings are and disable that option.
