When should I use ad delegates?

For many developers, the use of our ad delegates is not necessary.  Here are some reasons why you might need them:

• When you intend to use Rewarded Video.  See our iOS and Android documentation for more information on integrating rewarded video.
• When you need information on a user's interaction with an ad.  For instance, if you need to know when a user closes an interstitial video ad so you can resume background music in your app.
• When you need information about an ad unit's lifecycle.  For instance, if you need to know when a banner changes, an interstitial begins obstructing the screen, etc.
