title: Objective-c : How to store a large amount of data (iOS RSS application)
body: <p>I'm currently working on a Google Reader application on iOS and I would like to know what is the best way to store all the previously downloaded data (which could go up to thousands of news) ? I heard of Core Data, is it the way ? Or would it be easier to store an XML or JSON file and to parse it ?</p>
  
  <p>Thank you</p>
