title: iOS / Core Data - How can I change sectionNameKeyPath of a NSFetchedResultsController?
body: <p>I declared my fetchedResultsController like this </p>
  
  <pre><code>NSFetchedResultsController *fetchController = [[NSFetchedResultsController alloc] 
  initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext 
  sectionNameKeyPath:@"date" cacheName:nil]; 
  </code></pre>
  
  <p>But when I click on a UISegmentedControl, I want to change the sectionNameKeyPath to be @"title".</p>
  
  <p>Do you know a way to do so ?</p>
  
  <p>Thanks</p>
