this is probably a dumb question, but I would like to be notified when a ChartBoost-ad is displaying for the user. I see in the chartboost.h, there is a a few delegates, one in particular of interest, the didDisplayInterstatial.
I do not however know how to implement this, or if it is used for this at all.
chartboost.h
@protocol ChartboostDelegate <NSObject>
@optional
/// All of the delegate methods below are optional.
/// Implement them only when you need to more finely control Chartboost's behavior.
/// Called before requesting an interestitial from the back-end
- (BOOL)shouldRequestInterstitial:(CBLocation)location;
// Called when an interstitial has been displayed on the screen.
- (void)didDisplayInterstitial:(CBLocation)location;
Thanks
