// 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:UITableViewCellStyleDefault reuseIdentifier:@"en"] autorelease];

      cb = [[UIButton alloc] initWithFrame:CGRectMake(5,10, unselectedImage.size.width, unselectedImage.size.height)];

    [cb setImage:unselectedImage forState:UIControlStateNormal];
    [cb setImage:selectedImage forState:UIControlStateSelected];
    [cb addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchDown];
    [cell.contentView addSubview:cb];

    }

    if ( tableView == myTableView )
    {
      titleLabel = [[UILabel alloc]initWithFrame:CGRectMake(60, 0, 150, 35)];
      titleLabel.font = [UIFont boldSystemFontOfSize:13];
      titleLabel.textColor = [UIColor blackColor];  
      [cell.contentView addSubview:titleLabel];

      cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; 
    }

      return cell;
    }

If I understand the TableView concept correctly, you need to save the checkmark setting somewhere else. If your cell gets scrolled out of view the TableViewController might release the cell. Then, when you’re asked to re-create the cell in your delegate, you have to restore it in the same state as before.
