title: Core Data - Saving & Retrieving Attributes - Sample Code
body: <p>I've gone through quite a few Core Data tutorials. Most of them show how to add a new object to an entity and how to display the updated array of fetched objects.</p>
  
  <p>My goal, however, is much simpler: I'd like one Table View Controller to change and save an attribute (in tableView didSelectRowAtIndexPath:) of an entity and another Table View Controller to display the new list of attributes of that entity (in tableView cellForRowAtIndexPath:). Like in the iPhone <em>Sounds</em> settings: 
  <a href="http://holyteddy.com/sounds.jpg" rel="nofollow">Sounds</a> and
  <a href="http://holyteddy.com/ringtone.jpg" rel="nofollow">Ringtones</a></p>
  
  <p>I still haven't figured out how the Managed Object should interact with those two Table View Controllers.
  Do you know of a helpful tutorial/sample code explaining that very simple process?
  Thanks very much in advance!
