Banner & MREC Ads

The following sections show you how to load and then show and hide a banner or MREC ad.

Loading a Banner or MREC

Banners

To load a banner, create a MAAdView object that corresponds to your ad unit and call its loadAd method. To show that ad, add the MAAdView object as a subview of your view hierarchy. Implement MAAdViewAdDelegate so that you are notified when your ad is ready. This also notifies you of other ad-related events.

#import "ExampleViewController.h"
#import <AppLovinSDK/AppLovinSDK.h>
@interface ExampleViewController()<MAAdViewAdDelegate>
@property (nonatomic, strong) MAAdView *adView;
@end
@implementation ExampleViewController
- (void)createBannerAd
{
self.adView = [[MAAdView alloc] initWithAdUnitIdentifier: @"«ad-unit-ID»"];
self.adView.delegate = self;
// Banner height on iPhone and iPad is 50 and 90, respectively
CGFloat height = (UIDevice.currentDevice.userInterfaceIdiom == UIUserInterfaceIdiomPad) ? 90 : 50;
// Stretch to the width of the screen for banners to be fully functional
CGFloat width = CGRectGetWidth(UIScreen.mainScreen.bounds);
self.adView.frame = CGRectMake(x, y, width, height);
// Set background or background color for banners to be fully functional
self.adView.backgroundColor = «background-color»;
[self.view addSubview: self.adView];
// Load the ad
[self.adView loadAd];
}
#pragma mark - MAAdDelegate Protocol
- (void)didLoadAd:(MAAd *)ad {}
- (void)didFailToLoadAdForAdUnitIdentifier:(NSString *)adUnitIdentifier withError:(MAError *)error {}
- (void)didClickAd:(MAAd *)ad {}
- (void)didFailToDisplayAd:(MAAd *)ad withError:(MAError *)error {}
#pragma mark - MAAdViewAdDelegate Protocol

- (void)didCollapseAd:(MAAd *)ad {}
#pragma mark - Deprecated Callbacks

- (void)didHideAd:(MAAd *)ad { /* DO NOT USE - THIS IS RESERVED FOR FULLSCREEN ADS ONLY AND WILL BE REMOVED IN A FUTURE SDK RELEASE */ }
@end

MRECs

To load an MREC ad, create a MAAdView object corresponding to your ad unit and call its loadAd method. To show the ad, add the MAAdView object as a subview of your view hierarchy. Implement MAAdViewAdDelegate so that you are notified when your ad is ready. This also notifes you of other ad-related events.

#import "ExampleViewController.h"
#import <AppLovinSDK/AppLovinSDK.h>
@interface ExampleViewController()<MAAdViewAdDelegate>
@property (nonatomic, strong) MAAdView *adView;
@end
@implementation ExampleViewController
- (void)createMRECAd
{
self.adView = [[MAAdView alloc] initWithAdUnitIdentifier: @"«ad-unit-ID»" adFormat: MAAdFormat.mrec];
self.adView.delegate = self;
// MREC width and height are 300 and 250 respectively, on iPhone and iPad
CGFloat width = 300;
CGFloat height = 250;
// Center the MREC
CGFloat x = self.view.center.x - 150;
self.adView.frame = CGRectMake(x, y, width, height);
// Set background or background color for MREC ads to be fully functional
self.adView.backgroundColor = «background-color»;
[self.view addSubview: self.adView];
// Load the ad
[self.adView loadAd];
}
#pragma mark - MAAdDelegate Protocol
- (void)didLoadAd:(MAAd *)ad {}
- (void)didFailToLoadAdForAdUnitIdentifier:(NSString *)adUnitIdentifier withError:(MAError *)error {}
- (void)didClickAd:(MAAd *)ad {}
- (void)didFailToDisplayAd:(MAAd *)ad withError:(MAError *)error {}
#pragma mark - MAAdViewAdDelegate Protocol
- (void)didExpandAd:(MAAd *)ad {}
- (void)didCollapseAd:(MAAd *)ad {}
#pragma mark - Deprecated Callbacks
- (void)didDisplayAd:(MAAd *)ad { /* DO NOT USE - THIS IS RESERVED FOR FULLSCREEN ADS ONLY AND WILL BE REMOVED IN A FUTURE SDK RELEASE */ }
- (void)didHideAd:(MAAd *)ad { /* DO NOT USE - THIS IS RESERVED FOR FULLSCREEN ADS ONLY AND WILL BE REMOVED IN A FUTURE SDK RELEASE */ }
@end

Destroying Banners and MREC Ads

You may no longer need a MAAdView instance. This may happen, for example, if the user purchases ad removal. Deallocate such a MAAdView instance in order to free resources.

Do not deallocate the MAAdView instance if you use multiple instances with the same Ad Unit ID.

[self.adView removeFromSuperview];
self.adView.delegate = nil;
self.adView = nil;

Adaptive Banners

Adaptive banners are responsive banners with heights that derive from the device type and the width of the banner. You integrate adaptive banners in a similar way to how you integrate regular banners, except that you must set the height to the value returned by MAAdFormat.banner.adaptiveSize.height instead of to a constant like 50 or 90.

For more specific integrations you can set a custom width by using the local extra parameters API (as of Google adapter version 10.2.0.2 and Google Ad Manager adapter version 10.2.0.1).

You can fetch the appropriate height for your custom adaptive banner by using the adaptive size API. Before you load the ad, set the banner extra parameter adaptive_banner to true as is shown in the code below:

- (void)createBannerAd
{
self.adView = [[MAAdView alloc] initWithAdUnitIdentifier: @"«ad-unit-ID»"];
self.adView.delegate = self;
// Get the adaptive banner height
CGFloat height = MAAdFormat.banner.adaptiveSize.height;
// Stretch to the width of the screen for banners to be fully functional
CGFloat width = CGRectGetWidth(UIScreen.mainScreen.bounds);
self.adView.frame = CGRectMake(x, y, width, height);
[self.adView setExtraParameterForKey: @"adaptive_banner" value: @"true"];
[self.adView setLocalExtraParameterForKey: @"adaptive_banner_width" value: @400];
[self.adView.adFormat adaptiveSizeForWidth: 400].height; // Set your ad height to this value
// Set background or background color for banners to be fully functional
self.adView.backgroundColor = «background-color»;
[self.view addSubview: self.adView];
// Load the ad
[self.adView loadAd];
}

You may need to configure your UI based on the adaptive banner size. If so, you can retrieve the width and height of the loaded ad, in points, with code like the following:

- (void)didLoadAd:(MAAd *)ad
{
CGSize adViewSize = ad.size;
CGFloat widthDp = adViewSize.width;
CGFloat heightDp = adViewSize.height;
}

Stopping and Starting Auto-Refresh

You may want to stop auto-refresh for an ad. You may want to do this, for instance, when you hide a banner ad or you want to manually refresh. Stop auto-refresh for a banner or MREC ad with the following code:

// Set this extra parameter to work around SDK bug that ignores calls to stopAutoRefresh()
[adView setExtraParameterForKey: @"allow_pause_auto_refresh_immediately" value: @"true"];
[adView stopAutoRefresh];

Start auto-refresh for a banner or MREC ad with the following call:

[adView startAutoRefresh];

Manually refresh the contents with the following call. You must stop auto-refresh before you call loadAd().

[adView loadAd];
