AppLovin Banner Ad Crash on iPad

Question

I am trying to integrate AppLovin Banner Ads into my Universal App. On iPhone, it works fine. But on iPad, there is a crash of the app after the view with the banner is left/dismissed by the user.

Here is the code to show the banner ad:

// Create new AdView
adView = [[ALAdView alloc] initBannerAd];

//
// (Optional) Position the ad at the bottom of screen. By default
// it would be postitioned at (0,0)
//
adView.frame = CGRectMake( 0,
                          self.view.frame.size.height - adView.frame.size.height,
                          adView.frame.size.width,
                          adView.frame.size.height );

adView.autoresizingMask =
UIViewAutoresizingFlexibleLeftMargin |
UIViewAutoresizingFlexibleTopMargin |
UIViewAutoresizingFlexibleWidth |
UIViewAutoresizingFlexibleRightMargin;

// (Mandatory) Add the ad into current view
[self.view addSubview:adView];

// (Mandatory) Trigger loading of the new ad.
[adView loadNextAd];

If I comment out the addSubview invocation, no crash occurs. It seems like the added subview does not get unitialized or something.

Your help is much appreciated!

The problem was that the parent controller was not specified. Adding

adView.parentController = self;

solved the problem. Here is the final code:

// Create new AdView
adView = [[ALAdView alloc] initBannerAd];
adView.parentController = self;

// (Optional) Position the ad at the bottom of screen.
// By default it would be postitioned at (0,0)
adView.frame = CGRectMake( 0,
                          self.view.frame.size.height - adView.frame.size.height,
                          adView.frame.size.width,
                          adView.frame.size.height );

adView.autoresizingMask =
UIViewAutoresizingFlexibleLeftMargin |
UIViewAutoresizingFlexibleTopMargin |
UIViewAutoresizingFlexibleWidth |
UIViewAutoresizingFlexibleRightMargin;

// (Mandatory) Add the ad into current view
[self.view addSubview:adView];

// (Mandatory) Trigger loading of the new ad.
[adView loadNextAd];
