title: convertPoint:toView: Doesn't seem to be working
body: <p>I have a TableView with custom TableCellViews that has UILabels and UIButtons on it.
  when one of the buttons is taped I want to show a "tooltip" describing the text of the button.</p>
  
  <p>Most everything is working except for when I try to convert the center coordinates of the UIButton to the coordinates of the rootView which is a UIView.</p>
  
  <p>Here is the code:</p>
  
  <pre><code>- (void) fancyLabelButtonPressed: (UIButton *) button {
    CGPoint btnPoint = button.center;   // x=200.5 y=27.5
    CGPoint rootViewPoint = [button convertPoint:btnPoint toView:rootView];
    // rootViewPoint -&gt; x=390.5 y=197.5
    CGPoint pointToUse = CGPointMake(btnPoint.x +20, rootViewPoint.y - 23); // Hack to get it close
  }
  </code></pre>
  
  <p>How can <code>rootViewPoint.x=390.5</code> when I'm in portrait view?!!?  By using the x from the button and the y from the rootViewPoint I get close to what it should be but it is just a hack.</p>
  
  <p>Does anyone see what I'm doing wrong? or is there a better way?</p>
