I am working on an application for iOS which needs to synchronize data between multiple users and one web server. I did some research and the best solution I found for this is working with JSON. At the moment I have a .json file on a web server and I am able to download the data to my iphone app and parse it. I have two problems I didn't manage to understand yet: 1. How can each iphone user write back data to the json file on the server? 2. How can I take a data table and automaticly convert it to a .json file? so the .json file on the server will be updated every few minutes or so...
I'll appreciate any help with this!
