title: Format date and time after device current region settings
body: <p>I have an NSDate object from which I make two NSStrings: The date and the time. Currently I format the date as 20111031 and time as 23:15.</p>
  
  <p>What I would like to do is to format it to the device (iPhone, iPad, iPod Touch) current region settings (not the language!). So for instance:</p>
  
  <ul>
  <li>A device set to region US would show (from the top of my head) 10.31.11 and time 11:15 pm</li>
  <li>A device set to region the Netherlands would show: 31-10-2011 and time 23.15</li>
  <li>A device set to region Swedish would show: 2001-10-31 and time 23:15</li>
  </ul>
  
  <p>How can I do this?</p>
