Where can I find sample code for integrating iAds within my application?

I'm just starting to learn how to integrate iAds within my application. I have read all of the documentation on this provided by Apple开发者_如何学JAVA, but I still have some questions about the process. Is there any sample code or better documentation out there that shows how to place iAds within an application?

I doubt you'll find any public sample code for this until Apple lifts the NDA on iOS 4, and even then it might take a while.

In the meantime, you should watch Session 112 - Integrating Ads with iAd from the freely available WWDC 2010 videos.
