body: <p>How to access to subview in the cell of tableview?
  In the method "sliderValueChange" I need to access to the label in the cell.</p>
  
  <p>This is my code:</p>
  
  <pre><code>// Customize the appearance of table view cells.
  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      static NSString *CellIdentifier = @"Cell";
      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
  
      if (cell == nil) {
  
          cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
          cell.selectionStyle = UITableViewCellSelectionStyleNone;
          cell.textLabel.font = [UIFont boldSystemFontOfSize:15];
  
      }
          cell.textLabel.text = @"Soglia";
  
          UISlider *slider = [[[UISlider alloc] initWithFrame:CGRectMake(174,12,168,23)] autorelease];
          slider.maximumValue = 70;
          slider.minimumValue = 5;
          [cell addSubview:slider];
  
          cell.accessoryView = slider;
          [slider addTarget:self action:@selector(sliderValueChange:) forControlEvents:UIControlEventValueChanged];
          [slider release];
  
          UILabel *labelVal = [[UILabel alloc] initWithFrame:CGRectMake(218, 40, 30, 23)];
          labelVal.text = @"0";
          [cell addSubview:labelVal];
  
      return cell;
  
  }
  
  - (void)sliderValueChange:(id)sender {
      UISlider *theSlider = (UISlider *)sender;
      UITableViewCell *cell = (UITableViewCell *)theSlider.superview;
      UITableView *tableView = (UITableView *)cell.superview;
  
      //here I need to access to labelVal...
  
  }
  </code></pre>
