Interstitial Ads

Interstitial ads are full-screen or full-page ads that temporarily cover an app’s interface. They’re typically shown at natural pauses or transition points—such as after completing a level in a game or when navigating between major views.

The following sections show you how to load and then show an interstitial ad.

Loading an Interstitial Ad

To load an interstitial ad, instantiate an MAInterstitialAd object that corresponds to your ad unit and call its loadAd() method. Implement MAAdDelegate so that you are notified when your ad is ready. This also notifies you of other ad-related events.

Objective-C
Swift

#import "ExampleViewController.h"
#import <AppLovinSDK/AppLovinSDK.h>

@interface ExampleViewController()<MAAdDelegate>
@property (nonatomic, strong) MAInterstitialAd *interstitialAd;
@property (nonatomic, assign) NSInteger retryAttempt;
@end

@implementation ExampleViewController

- (void)createInterstitialAd
{
  self.interstitialAd = [[MAInterstitialAd alloc] initWithAdUnitIdentifier: @"«ad-unit-ID»"];
  self.interstitialAd.delegate = self;

  // Load the first ad
  [self.interstitialAd loadAd];
}

#pragma mark - MAAdDelegate Protocol

- (void)didLoadAd:(MAAd *)ad
{
  // Interstitial ad is ready to be shown. '[self.interstitialAd isReady]' will now return 'YES'

  // Reset retry attempt
  self.retryAttempt = 0;
}

- (void)didFailToLoadAdForAdUnitIdentifier:(NSString *)adUnitIdentifier withError:(MAError *)error
{
  // Interstitial ad failed to load
  // AppLovin recommends that you retry with exponentially higher delays up to a maximum delay (in this case 64 seconds)

  self.retryAttempt++;
  NSInteger delaySec = pow(2, MIN(6, self.retryAttempt));

  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, delaySec * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
    [self.interstitialAd loadAd];
  });
}

- (void)didDisplayAd:(MAAd *)ad {}

- (void)didClickAd:(MAAd *)ad {}

- (void)didHideAd:(MAAd *)ad
{
  // Interstitial ad is hidden. Pre-load the next ad
  [self.interstitialAd loadAd];
}

- (void)didFailToDisplayAd:(MAAd *)ad withError:(MAError *)error
{
  // Interstitial ad failed to display. AppLovin recommends that you load the next ad.
  [self.interstitialAd loadAd];
}

@end

class ExampleViewController: UIViewController, MAAdDelegate
{
  var interstitialAd: MAInterstitialAd!
  var retryAttempt = 0.0

  func createInterstitialAd()
  {
    interstitialAd = MAInterstitialAd(adUnitIdentifier: "«ad-unit-ID»")
    interstitialAd.delegate = self

    // Load the first ad
    interstitialAd.load()
  }

  // MARK: MAAdDelegate Protocol

  func didLoad(_ ad: MAAd)
  {
    // Interstitial ad is ready to be shown. 'interstitialAd.isReady' will now return 'true'

    // Reset retry attempt
    retryAttempt = 0
  }

  func didFailToLoadAd(forAdUnitIdentifier adUnitIdentifier: String, withError error: MAError)
  {
    // Interstitial ad failed to load
    // AppLovin recommends that you retry with exponentially higher delays up to a maximum delay (in this case 64 seconds)

    retryAttempt += 1
    let delaySec = pow(2.0, min(6.0, retryAttempt))

    DispatchQueue.main.asyncAfter(deadline: .now() + delaySec) {
      self.interstitialAd.load()
    }
  }

  func didDisplay(_ ad: MAAd) {}

  func didClick(_ ad: MAAd) {}

  func didHide(_ ad: MAAd)
  {
    // Interstitial ad is hidden. Pre-load the next ad
    interstitialAd.load()
  }

  func didFail(toDisplay ad: MAAd, withError error: MAError)
  {
    // Interstitial ad failed to display. AppLovin recommends that you load the next ad.
    interstitialAd.load()
  }
}

Showing an Interstitial Ad

To show an interstitial ad, call showAd() on the MAInterstitialAd object that you instantiated:

Objective-C
Swift

if ( [self.interstitialAd isReady] )
{
  [self.interstitialAd showAd];
}

if interstitialAd.isReady
{
  interstitialAd.show()
}
