body: <p>How can I get the rect size of a UITableViewCell? </p>
  
  <p>I am trying to display a pop hover every time the user clicks on a cell, and would like the pop hover to appear centered on every cell:</p>
  
  <pre><code>[replyPopover presentPopoverFromRect:CGRectMake(77, 25, 408, 68) 
                                inView:self.view 
              permittedArrowDirections:UIPopoverArrowDirectionDown 
                              animated:YES];
  </code></pre>
