title: Is it possible to set wide space in UITextField
body: <p>I have a <code>UITextField</code> which basically take 4 digit <code>NSInteger</code>. Now I want to bring the <strong>"Pass code"</strong> look into it. What I mean is there will be a certain space between each digit. Something like the below picture.</p>

  <p>I know I can put space at the font &amp; back side of my <code>UITextField</code>, but I want a certain distance in between my each input character. Is it possible in iOS? If yes than any kind of suggestion of guide line will be highly appreciated.</p>
  
  <p>Thanks a lot in advance.</p>
