title: Tab Bar iOS - Filter Core Data Only
body: <p>I have a concept question, that i am having real issues with.</p>
  
  <p>I have a Master/Detail application that i would like to add a Tab Bar to, but only to filter core data, basically just changing the predicate for the Fetch Request.</p>
  
  <p>Now, i could add a Tab Bar, add my Navigation Controller to it, modify some code and make it work. But i would then need to create multiple screens/fetch controllers e.t.c for each view i wish to display. Whereas what i would like to do is just re-filter the results on a change in the Tab Bar.</p>
  
  <p>Please excuse me if this is a stupid question, i am coming from an OSX background, and on that it is very straightforward!</p>
  
  <p>Thanks in Advance!</p>
