title: Persisting ListView
body: <p>I'm building a listview and getting it's data from Parse.com. At the moment, every time the app loads up it queries for new data from Parse.com, causing the whole listview to load.</p>
  
  <p>I'd like a situation where the listview references a local datasource and only go to Parse.com if new data is available. Somewhat similar to what the instagram app does whereby when you load it up, the list view is already populated and would get updated if needed.</p>
  
  <p>I have tried ParseQuery Cache policies but the behavior still stays the same. What would be the most efficient way of implementing this feature?</p>
  
  <p>Thanks in advance.</p>
