iOS应用程序从服务器获取数据

Question

I will be writing an IOS app that will query data from a server. What is the proper method to request and retrieve data in that manner. None of the books I'm reading seem to be covering it. I imagine the server would be using something like PHP and it would have access to the database. Would the iOS app do something like XML-RPC and i write php functions to listen, retrieve, and respond? Is XML-RPC even still the hip solution or is there something more modern I've not used yet?

The iOS app will be ultimately trying to get information from a Firebird database.

Well, if you're creating an iOS 5 app, then you're on luck, you can use restful webservices very easily:

NSString* response = [NSString stringWithContentsOfURL:<url pointing to your server> error:&error];

Then you can use NSJsonSerialization to convert the response into a property list. Also there are convenience methods for parsing XML files.
