title: How can I tell when something outside my UITableViewCell has been touched?
body: <p>Similar to <a href="https://stackoverflow.com/questions/1591738/resignfirstresponder-when-tapping-uitableview">this question</a> I have a custom subclass of UITableViewCell that has a UITextField.  Its working fine except the keyboard for doesn't go away when the user touches a different table view cell or something outside the table.  I'm trying to figure out the best place to find out when something outside the cell is touched, then I could call resignFirstResponder on the text field.</p>
  
  <p>If the UITableViewCell could receive touch events for touches outside of its view then it could just resignFirstResponder itself but I don't see any way to get those events in the cell.</p>
  
  <p><strong><em>EDIT:</strong> I tried this (below) in my UITableViewCell subclass but it doesn't work, I think because touchesBegan:withEvent: doesn't get called if the event was handled by a control.  I think I need to catch the events before they get send down the responder chain somehow.</em>  </p>
  
  <p>The solution I'm considering is to add a touchesBegan:withEvent: method to the view controller.  There I could send a resignFirstResponder to all tableview cells that are visible except the one that the touch was in (let it get the touch event and handle it itself).</p>
  
  <p>Maybe something like this pseudo code:</p>
  
  <pre><code>- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
      CGPoint touchPoint = // TBD - may need translate to cell's coordinates
  
      for (UITableViewCell* aCell in [theTableView visibleCells]) {
          if (![aCell pointInside:touchPoint withEvent:event]) {
               [aCell resignFirstResponder];
          }
      }
  }
  </code></pre>
  
  <p>I'm not sure if this is the best way to go about this.  There doesn't seem to be any way for the tableviewcell itself to receive event notifications for events outside its view.</p>
  
  <p><strong><em>EDIT2:</strong> I thought I had an answer (I even posted it as an answer) using hitTest:withEvent: but that didn't work out.  It doesn't always get called.  :-(</em></p>
