title: iOS Loading Data From A Web Server - Best Practices?
body: <p>I've been working on my first iOS app and I finally have something that works like I intended. This app reads in an XML file, parses that data and displays what needs to be listed - a list of profiles actually. What I want to do know is have the app check a web service (I'll code this in PHP) and retrieve this XML file.</p>
  
  <p>So my question are: What is the best practice for handling this? Should I keep my data in an XML file or use something else (JSON I think)? What are the standard approaches a more experience developer would take?</p>
  
  <p>What I envision is there's a web site that a user can enter their information in, which then stores their profile information in a database. Then the web service simply pulls this data and provides it to the phone.</p>
