title: Prevent custom UITableViewCell from duplicating
body: <p>I have a custom UITableViewCell with an WishInfoTextView, just a subclass of UILabel.</p>
  
  <pre><code> static NSString *CellIdentifier = @"Cell";
   NSMutableDictionary* item = [myWishes objectAtIndex: indexPath.row];
  
  WishTableViewCell* cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier];
  if( cell == nil ) {
      cell = [[WishTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
      [cell setSelectionStyle: UITableViewCellEditingStyleNone];
      [cell setWishInfo: item];
  }    
  
  WishInfoTextView* infoText = (WishInfoTextView*)[cell viewWithTag: kTableInfoText];
  infoText.text = [item objectForKey:@"name"];
  
  NSLog(@"\nTaggedText: %@\nNormalText: %@", infoText.wishName, [item objectForKey:@"name"]);
  </code></pre>
  
  <p>Only the problem is that i have duplicated cells. I read something about setting tags.
  But if i access my label by his tag, nothing changes. </p>
