title: UIAttachmentBehavior in UITableViewCell
body: <p>I've added a horizontal UIPanGestureRecognizer to my tableviewcell to pan a subview of the cell, like the way the ios7 mail app does to reveal delete and more options and this works as expected</p>
  
  <pre><code>- (IBAction)slideCell:(UIPanGestureRecognizer *)sender
  {
  
      CGPoint locationOfPan = [sender locationInView:self.tableView];
      NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:locationOfPan];
      TestCell *cell = (TestCell *)[self.tableView cellForRowAtIndexPath:indexPath];    
  
      if (sender.state == UIGestureRecognizerStateChanged) {
          CGPoint translation = [sender translationInView:self.tableView];
          [cell.view setCenter:CGPointMake(cell.view.center.x + translation.x, cell.view.center.y)];
          [sender setTranslation:CGPointMake(0, 0) inView:self.tableView];
      }
  }
  </code></pre>
  
  <p>What I would also like to do is add a UIAttachmentBehavior with an anchor point to each of my UITableViewCells so that when I pan the <code>cell.view</code> horizontally I feel some resistance  and then when I let go, the view in the cell that was panned springs back to it's original anchor position on the x axis, is this possible to do with UIDynamics?</p>
  
  <p>Also can I set one side of the cell as a boundary which prevents a user from panning the contained view beyond it?</p>
