Unit Delegate Protocol

Implementing the Unit Delegate Methods

Important

IAParentViewControllerForUnitController:unitController is a required delegate method.
When an ad transits to full-sreen, IASDK will need to get a "parent" view controller, and this method will be invoked. If it is not implemented, the app will crash with an exception, intentionally, to show that there is a required method implementation is missing.

This delegate method is required to get a client-side view controller to present modal views, such as in-app browser, storekit controller, MRAID expand, etc. In this method, a desired view controller should be returned by the client side. In most cases it will be the same view controller that presents an ad. 

Parent View Controller

IAParentViewControllerForUnitController:
Parent view controller evaluation from a publisher, in order to render ads in full-screen / modal mode.
Example:

Example Code
- (UIViewController * _Nonnull)IAParentViewControllerForUnitController:(IAUnitController * _Nullable)unitController {
  return self; // in case 'self' is a UIViewController subclass;
}

Note

All other delegate methods of this protocol (interface) are optional.

User Click

IAAdDidReceiveClick:
This method will be invoked when user clicks an ad:

Example Code
- (void)IAAdDidReceiveClick:(IAUnitController * _Nullable)unitController {
  NSLog(@"ad did click");
}

Ad Impression

IAAdWillLogImpression:
This method will be invoked when ad is rendered and visible:

Ad Impression Method

- (void)IAAdWillLogImpression:(IAUnitController * _Nullable)unitController {
  NSLog(@"ad impression");
}

Future Fullscreen Transition Notification

IAUnitControllerWillPresentFullscreen:
This means that the transition to fullscreen mode will be performed.

Transition Notification

- (void)IAUnitControllerWillPresentFullscreen:(IAUnitController * _Nullable)unitController {
  NSLog(@"ad will present fullscreen");
} 
Notification of Performed Fullscreen Transition

IAUnitControllerDidPresentFullscreen:
This means the transition to fullscreen already performed.

Notification of Successful Transition
- (void)IAUnitControllerDidPresentFullscreen:(IAUnitController * _Nullable)unitController {
  NSLog(@"ad did present fullscreen");
}

Future Transition from Fullscreen Notification

IAUnitControllerWillDismissFullscreen:
This means that the transition from fullscreen mode will happen.

Future Fullscreen Transition

(void)IAUnitControllerWillDismissFullscreen:(IAUnitController * _Nullable)unitController {
  NSLog(@"ad will dismiss fullscreen");
}

Notification of Performed Transition from Fullscreen Mode

IAUnitControllerDidDismissFullscreen:
This means that the transition from fullscreen mode already performed.

Successfully Performed Transition

(void)IAUnitControllerDidDismissFullscreen:(IAUnitController *_Nullable)unitController {
  NSLog(@"ad did dismiss fullscreen");
}

Opening an External App Notification

IAUnitControllerWillOpenExternalApp:
This is a notification that your app will move to the background, and an external app such as Safari, the App Store, or a Universal link-supported app will open.

Notifying of Opening an External App

(void)IAUnitControllerWillOpenExternalApp:(IAUnitController *_Nullable)unitController {
  NSLog(@"ad will open external app");
}
