It is written in the document I have read on Google's site that it is necessary to call GADMobileAds.configureWithApplicationID()
at some point, as in the following code for example.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Initialize GoogleMobileAds.
GADMobileAds.configureWithApplicationID("ca-app-pub-7876539281098811~369988223322")
return true
}
But when testing the app, things seem to work fine whether this function is called or not. So is it important to call it? Does it play an identification role or something similar?
