Full-Screen Ads (complete example) with Swift

FlurryForPublishers_Interstitial.swift

class ViewController: UIViewController, FlurryAdInterstitialDelegate {
    let adInterstitial = FlurryAdInterstitial(space:"ADSPACE");
    
    override func viewDidAppear(animated: Bool) {
      super.viewDidAppear(animated);
      adInterstitial.adDelegate = self;
      adInterstitial.fetchAd();
    }
    
    override func viewDidDisappear(animated: Bool) {
      super.viewDidDisappear(animated);
    }
    
    /**
    * Invoke an interstitials at a natural pause in your app. For example, when a
    * level is completed, an article is read or a button is pressed. Here we
    * mock the display of ant interstitials when a button is pressed.
    */
    @IBAction func showFullScreenAdClickedButton(sender: AnyObject) {
        if adInterstitial.ready {
            adInterstitial.presentWithViewController(self);
        } else {
            adInterstitial.fetchAd();
        }
    }
}

If you make the let adInterstitial a lazy property, users can inject a mock during testing. Good practice, but may complicate the example.

There should be no reason to test if adInterstitial != nil in the bottom method.
