title: Ordinal Month-day Suffix Option for NSDateFormatter setDateFormat
body: <p>What setDateFormat option for NSDateFormatter do I use to get a month-day's ordinal suffix?</p>
  
  <p>e.g. the snippet below currently produces:<br>
  3:11 PM Saturday August 15</p>
  
  <p>What must I change to get:<br>
  3:11 PM Saturday August 15<strong>th</strong></p>
  
  <pre><code>NSDate *date = [NSDate date];
  NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
  [dateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4];
  [dateFormatter setDateFormat:@"h:mm a EEEE MMMM d"];
  NSString *dateString = [dateFormatter stringFromDate:date]; 
  NSLog(@"%@", dateString);
  </code></pre>
  
  <p>In PHP, I'd use this for the case above:<br>
  <code>&lt;?php echo date('h:m A l F jS') ?&gt;</code></p>
  
  <p>Is there an NSDateFormatter equivalent to the <strong>S</strong> option in the PHP formatting string?</p>
