title: Get center of tableviewCell within coordinate system of superview of tableview
body: <p>You can get the center point of a cell within the coordinates of its superview or tableView using:</p>
  
  <pre><code>  CGPoint center = cell.center;
  </code></pre>
  
  <p>If the tableview's superview is a UIView, how do you get the cell's center point within the coordinates of the superview of the tableview?</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>The cell is in a tableView and the tableView is in self.view. I am mainly concerned about the y coordinate.  I did a test to see what the values should be but am not getting the desired result from convertPointToView:</p>
  
  <pre><code>//debugger values appear below each line
  CGRect viewRect = self.view.frame;
  //(origin = (x = 0, y = 0), size = (width = 320, height = 568))
  CGRect tableRect = self.tableView.frame;
  //(origin = (x = 0, y = 108), size = (width = 320, height = 411))
   CGPoint prelimcenter = cell.center;
  CGPoint center = prelimcenter;
  //(x = 160, y = 242)
  prelimcenter = [cell convertPoint:prelimcenter toView:self.view];
  // (x = 160, y = 526) 
  </code></pre>
  
  <p>I would expect the difference in the Y coordinate to be about 108 which is the difference in the frames.  However, the difference in the points using convertPoint is 284.  What could be wrong with my syntax/code?  </p>
