@protocol GADNativeAdDelegate <NSObject>
Identifies native ad assets.
Called just before presenting the user a full screen view, such as a browser, in response to clicking on an ad. Use this opportunity to stop animations, time sensitive interactions, etc.
Normally the user looks at the ad, dismisses it, and control returns to your application with the nativeAdDidDismissScreen: message. However, if the user hits the Home button or clicks on an App Store link, your application will end. The next method called will be the applicationWillResignActive: of your UIApplicationDelegate object.Immediately after that, nativeAdWillLeaveApplication: is called.
Called just after dismissing a full screen view. Use this opportunity to restart anything you may have stopped as part of nativeAdWillPresentScreen:.
Called just before the application will go to the background or terminate due to an ad action that will launch another application (such as the App Store). The normal UIApplicationDelegate methods, like applicationDidEnterBackground:, will be called immediately before this.
