title: Can't put a single quote before the year in NSDateFormatter
body: <p>I want to format my date as follows:</p>
  
  <pre><code>Mon, Apr 14 '09
  </code></pre>
  
  <p>The <code>dateFormat</code> I'm setting for my <code>NSDateFormatter</code> is <code>EEE, MMM dd 'yy</code> but it shows:</p>
  
  <pre><code>Mon, Apr 14 'yy
  </code></pre>
  
  <p>If I take out the single quote before the year, I get the last two digits of the year but it's not obvious that it's the year because the single quote is gone. Help?</p>
  
  <p>I've also tried putting <code>'''</code>, <code>'\''</code>, and <code>'\'''</code> before 'yy' but it doesn't work, although the last two produced <code>'yy</code> and <code>''09</code></p>
