How to sell several apps sharing vars in App Store?

Question

Hi everyone!

I'm struggeling with a problem.

I want to sell one app in AppStore. But, I want to sell it by parts.

For example, you can buy one football team, and later, buy each player separately. I thought share vars between several apps, but I dont know if it's possible.

Can anyone help me? Where can I take information about that?

Thank you!
