title: NSDateFormatter doesn't allow 24-hour format
body: <p>I have to display the <strong>date</strong> in my app, where i need to display that only in the format of <code>12 - hour format</code>, i have used this code to display the <code>date</code></p>
  
  <pre><code>NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
  [dateFormatter setDateFormat:kDateDisplayFormat];
  NSTimeZone *timeZone = [NSTimeZone systemTimeZone];
  [dateFormatter setTimeZone:timeZone];
  NSString *todaysDate = [NSString stringWithFormat:@"%@",[dateFormatter stringFromDate:[NSDate date]]];
  [[self lblPointsDate] setText:todaysDate];
  </code></pre>
  
  <p>here when i change my iPhone date format to 24-hour it display's in 24-hour format. I need to <strong>convert</strong> 24-hour to 12-hour format or make it <strong>display only in 12-hour format</strong>. How can i do this?</p>
