This is the AdMob example. In this example we will see how to integrate AdMob in the application. I will show you the easiest way to integrate AdMob in the application.
Step 1: Open the Xcode, Create a new project using View base application. Give the application “AdmobiPhone”.
Step 2: Xcode automatically creates the directory structure and adds essential frameworks to it. You can explore the directory structure to check out the content of the directory.
Step 3: Xpand classes and notice Interface Builder created the AdmobiPhoneViewController class for you and generated a separate nib, AdmobiPhoneViewController.xib for the “AdmobiPhone”.
Step 4: First go to www.admob.com site, we need to register in this site for AdMob. After login, goto Sites &Apps –> Add site/App –> Select a site or app type –> Select iPhone App (See figure 1)
Next we need to full fill details (See figure 2)
Now you can download the AbMob SDK, it is required for publishing Ads and drag drop into the Xcode project.
Step 5: We need to add framework in project, so select the framework -> add New Framework -> Select AudioTollbox.framework, MediaPlayer.framework,MessageUI.framework and SystemConfiguration.framework add in the Framework folder.
Step 6: We need to add one background image in the project.
Step 7: Open the AdmobiPhoneViewController.h file, in this file we need to import GADBannerView.h file and create a instance of GADBannerView class. So make the following changes:
#import <UIKit/UIKit.h>
#import "GADBannerView.h"
@interface AdmobiPhoneViewController : UIViewController {
GADBannerView *AbMob;
}
@end
Step 8: Now open the AdmobiPhoneViewController.m file and make the following changes in the file.
#import "AdmobiPhoneViewController.h"
#define AdMob_ID @"a14dccd0fb24d45" // You can get this id from www.admob.com. This is Publisher ID
@implementation AdmobiPhoneViewController
– (void)dealloc
{
AbMob.delegate = nil;
[AbMob release];
[super dealloc];
}
– (void)didReceiveMemoryWarning
{
// Releases the view if it doesn’t have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren’t in use.
}
#pragma mark – View lifecycle
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
– (void)viewDidLoad
{
[super viewDidLoad];
AbMob = [[GADBannerView alloc]
initWithFrame:CGRectMake(0.0,
self.view.frame.size.height –
GAD_SIZE_320×70.height,
GAD_SIZE_320×70.width,
GAD_SIZE_320×70.height)];
AbMob.adUnitID = AdMob_ID;
AbMob.rootViewController = self;
[self.view addSubview:AbMob];
GADRequest *r = [[GADRequest alloc] init];
r.testing = YES;
[AbMob loadRequest:r];
}
– (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
– (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
@end
Step 9: Now compile and run the application on the device.
