Adding Interstitial Ad to your iOS app

The Audience Network allows you to monetize your iOS apps with Facebook ads. An interstitial ad is a full screen ad that you can show in your app. Follow this guide to display this type of ad unit. Or, if you're interested in other kinds of ad units, see a list of available types.

Let's implement the following interstitial ad placement.

Step 1: Load and Show Interstitial Ad View

Step 2: Verify Impression and Click Logging

Step 3: How to Debug When Ad Not Shown

Step 4: Test Ads Integration

Step 1: Load and Show Interstitial Ad View

Ensure you have completed the Audience Network Getting Started and iOS Getting Started guides before you proceed.

  1. After you have created a new project from iOS Getting Started guide, open ViewController.h. Import the SDK header, declare that ViewController implements the FBInterstitialAdDelegate protocol and add an instance variable for the interstitial ad unit:
    #import <UIKit/UIKit.h>
    @import FBAudienceNetwork;
    @interface ViewController : UIViewController <FBInterstitialAdDelegate>
    @property (nonatomic, strong) FBInterstitialAd *interstitialAd;
  2. Next, implement viewDidLoad method and interstitialAdDidLoad in ViewController.m file.
    - (void) viewDidLoad 
      [super viewDidLoad];
      // Instantiate an InterstitialAd object. 
      // NOTE: the placement ID will eventually identify this as your App, you can ignore it for
      // now, while you are testing and replace it later when you have signed up.
      // While you are using this temporary code you will only get test ads and if you release
      // your code like this to the App Store your users will not receive ads (you will get a no fill error).
      self.interstitialAd = [[FBInterstitialAd alloc] initWithPlacementID:@"YOUR_PLACEMENT_ID"];
      self.interstitialAd.delegate = self;
      // For auto play video ads, it's recommended to load the ad 
      // at least 30 seconds before it is shown
      [self.interstitialAd loadAd];
    - (void)interstitialAdDidLoad:(FBInterstitialAd *)interstitialAd
      NSLog(@"Ad is loaded and ready to be displayed");
      if (interstitialAd && interstitialAd.isAdValid) {
        // You can now display the full screen ad using this code:
        [interstitialAd showAdFromRootViewController:self];
  3. Replace YOUR_PLACEMENT_ID with your own placement id string. If you don't have a placement id or don't know how to get one, refer to the Getting Started Guide. Choose your build target to be device and run the above code, you should see something like this:

When running ads in the simulator, change the setting to test mode to view test ads. Please go to How to Use Test Mode for more information.

Do not call loadAd on the FBInterstitialAd while the ad is being shown on the screen. If you need to load another FBInterstitialAd for future use, you can do so after the user closed the current one, for example in the interstitialAdDidClose callback.

Step 2: Verify Impression and Click Logging

Optionally, you can add the following functions to handle the cases when the ad is shown, clicked or closed by users:

- (void)interstitialAdWillLogImpression:(FBInterstitialAd *)interstitialAd 
  NSLog(@"The user sees the add");
  // Use this function as indication for a user's impression on the ad.

- (void)interstitialAdDidClick:(FBInterstitialAd *)interstitialAd
  NSLog(@"The user clicked on the ad and will be taken to its destination");
  // Use this function as indication for a user's click on the ad.

- (void)interstitialAdWillClose:(FBInterstitialAd *)interstitialAd
  NSLog(@"The user clicked on the close button, the ad is just about to close");
  // Consider to add code here to resume your app's flow

- (void)interstitialAdDidClose:(FBInterstitialAd *)interstitialAd
  NSLog(@"Interstitial had been closed");
  // Consider to add code here to resume your app's flow

Step 3: Debugging When Ad Is Not Shown

Add and implement the following function in your View Controller implementation file to handle ad loading failures and completions:

- (void)interstitialAd:(FBInterstitialAd *)interstitialAd didFailWithError:(NSError *)error
  NSLog(@"Ad failed to load");

When there is no ad to show, the interstitialAd:didFailWithError: will be called with error.code set to 1001. If you use your own custom reporting or mediation layer you might want to check the code value and detect this case. You can fallback to another ad network in this case, but do not re-request an ad immediately after.
