Let's learn how to appear admob in ios.

We can download admob lib from cocoapods.
so down load from cocoapods.
admob link CocoaPods link

First install cocoapods.
in the terminal.

pod install
	

In the project directory in terminal.

pod init
	

Open Podfile and insert.

pod 'Google-Mobile-Ads-SDK'
	

and in terminal.
pod install --repo-update

We also need another library.
Check image and install libraries

finally set admob in center.
in the appController.mm

// admob
self.adView = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];
self.adView.adUnitID = @"admob id";
self.adView.rootViewController = _viewController;
self.adView.frame = CGRectMake(
                               _viewController.view.frame.size.width - self.adView.frame.size.width,
                               _viewController.view.frame.size.height - self.adView.frame.size.height,
                               self.adView.frame.size.width,
                               self.adView.frame.size.height );
                                   
// header file
extern "C"{
    #import
