title: NSInvalidArgumentException', reason: '-[UITableViewWrapperView indexPathForCell:]
body: <p>OK, I have a problem with to upgrade from iOS 6 to 7.  iOS 6 works fine but I get the following error in iOS7</p>
  
  <p>I am not sure but I think the error occurs here.</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
  static NSString *CellIdentifier = @"Events Cell";
  
  UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
  if (cell == nil) {
      cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
  }
  
  // Configure the cell...
  Event *event = [self.fetchedResultsController objectAtIndexPath:indexPath];
  cell.textLabel.text = event.name;
  return cell;
  }
  </code></pre>
  
  <p>Basically when I call a TableViewCell, it brings up a Datepicker but when I hit the "Done" button it crashes.  Any clues?</p>
