Unity Ads cocos2d/ios example?

Hi all, I am new to unity ads and I have a need to integrate into an existing cocos2d project. I'm following the docs here:

http://unityads.unity3d.com/help/Documentation for Publishers/Integration-Guide-for-iOS

but having trouble where I need to configure the view controller as a delegate (Configuring your ViewController as a Delegate section). I'm not sure where to go from here since cocos2d is not your typical MVC style framework. I've searched online but come up with nothing that helps. Hoping someone here can point me in the right direction.

Thanks in advance for any tips!

 

Try this
[[UnityAds sharedInstance] setViewController:[CCDirector sharedDirector]];

 

Thanks
