title: UITableView - Delayed update when using sections
body: <p>I've been searching for a few days, and have continued to learn from reading the apple docs and various tutorials, but there's a problem which I can't seem to get a handle on.</p>
  
  <p>I have a simple app that keeps track of projects, with a single Core Data Entity (ProjectEntry). All the attributes are strings at the moment. It's basically a combination of Paul Hegarty's Core Data lectures and Tim Roadley's web tutorial. </p>
  
  <p>I can add and save Entities and populate a tableview with the data. For the moment, I'm using the CoreDataTableViewController subclass that Hegarty provides in the lecture. I'm mentioning that because...</p>
  
  <p>When my UITableView isn't divided into sections, the new information "instantly" appears in the UI after adding a new entry. However, when I add sections ( via sectionNameKeyPath), the new  data still saves, but shows up only after refreshing several times OR waiting 30 seconds before refreshing(via a pull-to-refresh mechanism, which Hegarty also provided).</p>
  
  <p>The tableview delegate methods all seem to be working, as do the NSFetchedResultsController's methods. Using the Stanford/Hegarty CoreDataTableViewController subclass in the past has yielded success, and I've learned a lot reading through the implementation file itself.</p>
  
  <p>The controllers are embedded in a Navigation controller, with the managed object context being passed among the controllers via the prepareForSegue method. Some simple logging shows me the managed object context, initially obtained via a UIManagedDocument, is being successfully passed along.</p>
  
  <p>I've tried the [self.tableview reloadData] and/or the beginUpdates/endUpdates in viewWillAppear, but the delay persists.</p>
  
  <p>What is it about dividing the tableview into sections that's causing the delay? Would calling reloadSections on the tableview be necessary? Like I said, the entries are saved with Core Data and the fetchedResultsController populates the non-sectioned tableview instantly...</p>
  
  <p>It's probably something obvious that I'm just missing, but any help would be appreciated.</p>
