スワイプ機能をトリガーすると、対応するセルでカウントが増加し、タップしている間はカウントが減少するように、uitableviewcell にカウントを追加する必要があります。

(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = nil;
    NSString *CellIdentifier = @"sample";
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }
    UISwipeGestureRecognizer *recognizer;

    recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapFrom:)];
    [self addGestureRecognizer:recognizer];
    self.tapRecognizer = (UITapGestureRecognizer *)recognizer;
    recognizer.delegate = self;
    [recognizer release];

    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];

    [self addGestureRecognizer:recognizer];
    [recognizer release];
    UILabel *cookieLabel = [[UILabel alloc] initWithFrame:CGRectMake(5,5, 120,30)];
    cookieLabel.text = @"hello";
    cookieLabel.font = [UIFont systemFontOfSize:15.0f];
    cookieLabel.textColor = [UIColor blackColor];
    cookieLabel.backgroundColor = [UIColor redColor];
    [cell.contentView addSubview:cookieLabel];
    [cookieLabel release];
    cell.selectionStyle = UITableViewCellSelectionStyleGray;

    costLabel = [[UILabel alloc] initWithFrame:CGRectMake( 200, 5, 230, 30)];
    //costLabel.text = handleSwipeFrom:;
    costLabel.font = [UIFont systemFontOfSize:15.0f];
    costLabel.textColor = [UIColor blackColor];
    costLabel.backgroundColor = [UIColor greenColor];
    [cell.contentView addSubview:costLabel];
    [costLabel release];
    [self setUserInteractionEnabled:YES];

    return cell;
}

UISwipeGestureRecognizer をセルに追加しないでください。UITableView に追加します。

TISwipeableTableView をベースとして使用し、正しく動作するように大幅に変更しました (独自のタッチ処理を行ったため、「奇妙で非ネイティブな」感覚が生じました)。

- (void)didSwipe:(UIGestureRecognizer *)gestureRecognizer {
  if ([MRUserDefaults sharedMRUserDefaults].isSwipeMenuEnabled) {
    if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
      CGPoint swipeLocation = [gestureRecognizer locationInView:self];
      NSIndexPath *swipedIndexPath = [self indexPathForRowAtPoint:swipeLocation];
      TISwipeableTableViewCell* swipedCell = (TISwipeableTableViewCell *)[self cellForRowAtIndexPath:swipedIndexPath];

      if ([swipedCell isKindOfClass:[TISwipeableTableViewCell class]]) {
        if (![swipedIndexPath isEqual:indexOfVisibleBackView]) {
          [self hideVisibleBackView:YES];
          [swipedCell revealBackView];
          [self setIndexOfVisibleBackView:swipedIndexPath];  

          if (swipeDelegate && [swipeDelegate respondsToSelector:@selector(tableView:didSwipeCellAtIndexPath:)]){
            [swipeDelegate tableView:self didSwipeCellAtIndexPath:[self indexPathForRowAtPoint:swipeLocation]];
          }        
        }
      }
    }  
  }
}

- (id)initWithFrame:(CGRect)frame style:(UITableViewStyle)style {
  if ((self = [super initWithFrame:frame style:style])) {
    if ([MRUserDefaults sharedMRUserDefaults].isSwipeMenuEnabled) {
      UIGestureRecognizer *swipeGesture = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipe:)] autorelease];
      [self addGestureRecognizer:swipeGesture];
    }
  }
  return self;
}

これで始められるはずです。
