    }
}


extension ViewController : MPInterstitialAdControllerDelegate {
    func loadInterstitial() {
        mopubInterstitial = MPInterstitialAdController(forAdUnitId: "<YOUR_ADUNIT_ID_HERE>")
        mopubInterstitial.delegate = self
        mopubInterstitial.loadAd()
    }
        
    func showInterstitial() {
        if(mopubInterstitial.ready) {
            mopubInterstitial.show(from: self);
        }
    }
        
    func interstitialDidLoadAd(_ interstitial: MPInterstitialAdController!) {
       
    }
}
