Copy core data database between two iphone

Question

Hi! I'm coding an app with core data. I need to sync the database between two iphones running the same app maybe via bonjour... Can anyone help?

Thankyou!

Answer 1

I would suggest using cocoahttpserver for the basic network communication. Now you can either

• copy your sqlite file if used in CoreData

or

• use some exchange-format (xml, json) on top of the server communication.

I myself would consider idea one being quite bad in most situations, also it might fit for your use-case.

With idea two you will have more work but more control about the data representation on each phone.

Actually we are using idea two in my company. But I can't post any code here.
