title: UITableViewCellAccessoryDisclosureIndicator isn't showing
body: <p>Scenario: Using custom cell UITableViewCell XIB (without any storyboard).
  <br/>
  Also: set accessor type within the NIB.  - I tried both within NIB &amp; via Code.</p>
  
  <p>Attempting to set the cell-accessor type:</p>
  
  <pre><code>cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
  </code></pre>
  
  <p>Result: No accessory type shown.</p>
  
  <p>Why?</p>
  
  <p>The cell only has two (2) labels with plenty of space available for the AccessoryView.
  Here's the cell code:</p>
  
  <pre><code>@interface MyStoreTableViewCell : UITableViewCell
  @property (weak, nonatomic) IBOutlet UILabel *addressLabel;
  @property (weak, nonatomic) IBOutlet UILabel *storeDistanceLabel;
  @end
  </code></pre>
  
  <p>Here's the body:</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
  MyStoreTableViewCell *cell = (MyStoreTableViewCell *)[tableView dequeueReusableCellWithIdentifier: CellIdentifier];
  
  Address *address = _storeAddresses[indexPath.row];
  [cell.contentView addSubview:self.storeAddressButtons[indexPath.row]];
  
  cell.addressLabel.attributedText = [NSAttributedString staplesNormalAttributeStringOf:[address toString] havingFont:[UIFont staplesLightMediumFont]];
  
  NSString *myString = [NSString stringWithFormat:@"%2.1f miles",[address.distance floatValue]];
  
  cell.storeDistanceLabel.attributedText = [NSAttributedString staplesNormalAttributeStringOf:myString havingFont:[UIFont staplesLightMediumFont]];
  
  // ...this doesn't have any effect:
  cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
  
  return cell;
  </code></pre>
  
  <p>}</p>
