Delegate Usage

By implementing Mediation delegate protocols you can get notifications about the success, failure, or lifecycle events of the Mediation SDK and its ad objects.

Mediation Start Delegate 🔗

Implement the HeliumSdkDelegate protocol to receive notifications about the Mediation SDK’s initialization process.

• swift
• objective-c

• extension AppDelegate: 
  

• @interface AppDelegate () <HeliumSdkDelegate>
  

This will allow you to implement the following method:

• swift
• objective-c

• func heliumDidStartWithError(_ error: ChartboostMediationSDK.ChartboostMediationError?) {
      if let error = error {
          print("Chartboost Mediation did not start due to error: \(error)")
      } else {
          print("Chartboost Mediation Started Successfully")
      }
  }
  

• - (void)heliumDidStartWithError:(nullable ChartboostMediationError *)error {
      if (error)
          NSLog(@"Mediation did not start due to error: %@", error);
      else
          NSLog(@"Mediation Started Successfully");
  }
  

Interstitial Ad Delegates 🔗

Implement the CHBHeliumInterstitialAdDelegate protocol to receive notifications about interstitial ads loading, displaying, and closing.

• swift
• objective-c

• extension ViewController: CHBHeliumInterstitialAdDelegate
  

• @interface ViewController () <CHBHeliumInterstitialAdDelegate>
  

This will allow you to implement the following methods:

• swift
• objective-c

• func heliumInterstitialAd(
      withPlacementName placementName: String,
      requestIdentifier: String,
      winningBidInfo: [String : Any]?,
      didLoadWithError error: ChartboostMediationSDK.ChartboostMediationError?
  ) {
      if let error = error {
          print("Interstitial with Placement Name:\(placementName) failed to load with error:\(error.localizedDescription)")
      } else {
          print("Interstitial with Placement Name:\(placementName) didLoad")
      }
  }
  
  func heliumInterstitialAd(
      withPlacementName placementName: String,
      didShowWithError error: ChartboostMediationSDK.ChartboostMediationError?
  ) {
      if let error = error {
          print("Interstitial with Placement Name:\(placementName) failed to show with error:\(error.localizedDescription)")
      } else {
          print("Interstitial with Placement Name:\(placementName) didShow")
      }
  }
  
  func heliumInterstitialAd(
      withPlacementName placementName: String,
      didCloseWithError error: ChartboostMediationSDK.ChartboostMediationError?
  ) {
      if let error = error {
          print("Interstitial with Placement Name:\(placementName) failed to close with error:\(error.localizedDescription)")
      } else {
          print("Interstitial with Placement Name:\(placementName) didClose")
      }
  }
  
  func heliumInterstitialAdDidRecordImpression(withPlacementName placementName: String) {
      print("Impression recorded")
  }
