These codes are used by cocos2d-x project;

Find AppController.mm and a method called "- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions ...";
And then place
[[AdmobHelper instance] addBanner:eaglView size:kGADAdSizeSmartBannerPortrait controller:_viewController];
below statement " _viewController.view = eaglView;""
