Integrating iAds

Weak Link iAds

Runtime check for iAds if (NSClassFromString(@"ADBannerView")) { // Setup AdView adView = [[ADBannerView alloc] initWithFrame ... }

Inside your UIViewController.h #import <iAd/iAd.h> @interface adSupportedNavigationController : UINavigationController <ADBannerViewDelegate>{ // iVars here } // @property is optional @property (nonatomic, retain) ADBannerView *adView; If you’ve weak linked the iAd Library, this won’t cause problems

Implement ADBannerViewDelegate // Apple sent you an ad! Display the ADBannerView from here - (void)bannerViewDidLoadAd:(ADBannerView *)banner; // Someone has tapped on an ad ($$) - (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave; // AdBannerView has finished - (void)bannerViewActionDidFinish:(ADBannerView *)banner; // *sigh* The most common message. Hide the ADBannerView - (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError: (NSError *)error;

End Result After you receive a test ad

Technical Caveats 1

Technical Caveats 1 • ADBannerView is a black box • ADBannerView must be displayed in a UIViewController subclass • Hide ADBannerView when there’s no ad • Sometimes test ads don’t display, sometimes they do.

Technical Caveats 2 • Apple decides when to serve you ads • Apple doesn’t care if you aren’t being served ads • How you handle ADBannerView via it’s delegate can determine the ads you get ADBannerViewDelegate Documentation: “preventing [ads displaying] may alter the advertisements your application sees and reduce the revenue your application earns through iAd.”

Fill Rate % and CTR % • FIll Rate • Percentage of total requests supplied with Ads • CTR = Click Through Rate • Percentage of people who click on an add

eCPM • Effective Cost Per 1000 (M) Impressions • Includes clicks * Source: Google AdSese Blog

Why so rubbish? My top 3 countries Where the iAds are released

What else can you do? • Integrate additional platforms; ADMob etc. • Sell apps for money •
