title: Core Data NSFetchedResultsController - Total number of records returned
body: <p>I'm using an NSFetchedResultsController in an iPhone app, and am wondering if there is some easy way of getting the total number of rows returned in all sections.</p>
  
  <p>Instead of getting the [[fetchedResultsController sections] count] and then looping through each section to get its count, can it be done in one line?</p>
  
  <p>Thanks!</p>
