title: iOS - How to add text on top of PDF Document?
body: <p>I've loaded a PDF Document into a UIView Class, and displayed it on screen using CGDrawRect. So Now I can visually see the PDF: What I want to do is have the user click certain points of the file, which will bring up the key board, allowing the user to directly add text to the PDF, which will later need to be rendered - some direction or guide would be very helpful ? </p>
  
  <ul>
  <li>I understand its a lot simpler to draw a PDF from scratch then to manipulate it </li>
  <li>I also understand Quartz 2d may be the way to go, but a bit confused with the samples </li>
  </ul>
