title: Checkbox cell in a table view: User can't check it
body: <p>I need help in using checkbox cell. I currently added the object to tableview. It looks ok until i tried building and running the program where I cannot check the checkbox. I am currently using a tableview which displays items runtime with a checkbox for each item so i can have multiple selections.</p>
  
  <p>I am new to xcode and I have been stuck for a week with this problem. i tried google but still no luck.</p>
  
  <p>Any snippets, answers, or explanations is very much appreciated.</p>
