How to deactivate iAd from a free game via inapp purchase?

Ok, i can use iAd with a kit from prime 31 and others i think but how can i then deactivate the iAd via inapp purchase (again i.e. from prime 31)?

This way i only have to submit one app for free and can earn money with iAd but can offer the customer to deactivate the iAd if he is willing to pay.

I also want to offer more features with the inapp purchase but to deactivate the iAd is the main question i do not know on how to do that and if it is allowed from Apple.

@m_stolly, after the use successfully purchases your product just destroy the iAd banner and don’t ever call createBanner again.

Thank you prime 31.
The side question that maybe do not come out clear is do Apple allow this?

Is there an App that do this that someone here has made?

There are dozens of apps that let you turn off ads for a price.

our game Ball-Hop Bowling does exactly what’s described here (although we didn’t use prime 31’s plugin… we ended up writing our own).

it’s free to download so you can check it out yourself…

How do you find the revenue etc from iAd? Any issues with the service? (I know this is a pretty old thread but didn’t want to start a new one on the same topic)
