Interstitial ads are full-screen ads that cover the interface of an app until closed by the user. They’re typically displayed at natural transition points in the flow of an app, such as between activities or during the pause between levels in a game. When an app shows an interstitial ad, the user has the choice to either tap on the ad and continue to its destination or close it and return to the app.
When building and testing your apps, make sure you use test ads rather than live, production ads.

After an ad loaded successfully, show your ad object when appropriate, your must specify a root view controller for the interstitial ad.
