iad is used to display ads, served by the apple server. iad helps us in earning revenue from an ios application.

iad integration – steps involved

step 1 − create a simple view-based application.

step 2 − select your project file, then select targets and then add iad.framework in choose frameworks.

step 3 − update viewcontroller.h as follows −

#import <uikit/uikit.h>
#import <iad/iad.h>

@interface viewcontroller : uiviewcontroller<adbannerviewdelegate> {
   adbannerview *bannerview;
}
@end

step 4 − update viewcontroller.m as follows −

#import "viewcontroller.h"

@interface viewcontroller ()
@end

@implementation viewcontroller

- (void)viewdidload {
   [super viewdidload];
   bannerview = [[adbannerview alloc]initwithframe:
   cgrectmake(0, 0, 320, 50)];
   
   // optional to set background color to clear color
   [bannerview setbackgroundcolor:[uicolor clearcolor]];
   [self.view addsubview: bannerview];
}

- (void)didreceivememorywarning {
   [super didreceivememorywarning];
   // dispose of any resources that can be recreated.
}

#pragma mark - adviewdelegates

-(void)bannerview:(adbannerview *)banner 
   didfailtoreceiveadwitherror:(nserror *)error {
   nslog(@"error loading");
}

-(void)bannerviewdidloadad:(adbannerview *)banner {
   nslog(@"ad loaded");
}

-(void)bannerviewwillloadad:(adbannerview *)banner {
   nslog(@"ad will load");
}

-(void)bannerviewactiondidfinish:(adbannerview *)banner {
   nslog(@"ad did finish");
}
@end

output

when we run the application, we'll get the following output −
