title: Unable to retrieve updatedAt or createdAt values from Parse objects
body: <p>I'm an experienced Android developer trying to get a prototype iOS app running using the Parse service and sdk (<a href="https://www.parse.com/" rel="noreferrer">https://www.parse.com/</a>).</p>
  
  <p>It's great, and i can get all my objects and their values with no trouble, everything works fine.</p>
  
  <p>However, i cannot get the updatedAt value automatically created by Parse for each object. <br>
  It's a must for me, and I dont want to have to save an aditional timestamp as a String when the data is sitting right there.</p>
  
  <p>This is the gist of what i was doing. </p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {
  
  static NSString *CellIdentifier = @"Cell";
  
  UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
  if (cell == nil) {
      cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
  }  
  
  // this works fine 
  cell.textLabel.text = [object objectForKey:@"name"];
  
  //substring however does not
  NSDate *updated = [object objectForKey:@"updatedAt"];
  NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
  [dateFormat setDateFormat:@"EEE, MMM d, h:mm a"];
  cell.detailTextLabel.text = [NSString stringWithFormat:@"Lasted Updated: %@", [dateFormat stringFromDate:update]];
  
  //i also tried like this at first
   cell.detailTextLabel.text = [NSString stringWithFormat:@"Lasted Updated: %@", [object objectForKey:@"updatedAt"]];
  
  return cell;
  </code></pre>
  
  <p>}</p>
