As I am learning to developing in iOS and I would make an iOS app.
I'd like to have a database on a server and the users of the app could access to it. Something like a mini-social network. An app where you can create a user and see/modify the data of the database.
Well, I may need a web service to get the iPhone communicates with the server but I've been searching and reading info and I don't know exactly how to do it.
A good tutorial or article to read? Some info will be appreciated :)
