Need one app to update another

[aheirich]

I have an app that maintains an sqlite3 database in its Documents directory. I want to sell expansion packs as separate apps. Each expansion pack contains a small database that the main app needs to add into its larger database.

My understanding is that each app can only access its own Documents directory and cannot access the documents of another app. If this is true then how can an expansion pack app add to the database of the main app?

thank you

you'll need to have a web server than can send updates to the main app, and the main app then uses the data received to update its sqlite db.

The idea above will work today but you may want to hold off until 3.0 or start developing under 3.0. It allows for buying in app so you could have just one app and have the user expand or buy directly inside the app.

thanks, it sounds like this is what I need. I want the expansion packs to sell through the app store.

Your app sounds very interesting! Do you mind me asking if the main one is already up and running in the app store? I'd like to try it out (can you message me or post me your app name?)!
