title: scrolling other UITableview at the same time as another UItableview
body: <p>I have a quite complicated view. What I basicly have is the following</p>
  
  <p><img src="https://i.stack.imgur.com/4zVWT.png" alt="enter image description here"></p>
  
  <p>You can see I have a <code>vertical tableview</code>. In each cell I have a <code>horizontal tableview</code>. What I want to do now is when I scroll one <code>horizontal tableview</code>, every other horizontal tableview should scroll also. </p>
  
  <p>In my subClass of the vertical tableviewCell I have the following.</p>
  
  <pre><code>  for(HorizontalTableCell *cell in mainTable.subviews){
          if([cell isKindOfClass:[HorizontalTableCell class]]){
              for(UITableView *cellTable in cell.subviews){
                  if([cellTable isKindOfClass:[UITableView class]]){
                      NSLog(@"cell table is table %@",cellTable);
                      [cellTable setContentOffset:CGPointMake(scrollView.contentOffset.x, 0) animated:NO];
                  }
              }
          }
      }
  </code></pre>
  
  <p>But this is not working OK. Can anybody help me with this?</p>
