Estoy tratando de encontrar seleccionadoUITableViewCell como sigue

 - (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:CellIdentifier];

  }
    if   ([indexPath row] == [tableView cellForRowAtIndexPath:indexPath.row]) // i want to place value of selected row to populate the buttons 

        //([indexPath row] == 0)

        //(indexPath.row == ![self cellIsSelected:indexPath]) 

    {
        UIButton *AddComment = [UIButton buttonWithType:UIButtonTypeCustom]; // custom means transparent it takes shape same with backgroup image

        [AddComment addTarget:self 
                       action:@selector(TestBtns:)
             forControlEvents:UIControlEventTouchDown];

        // [AddComment setTitle:@"1" forState:UIControlStateNormal];

        AddComment.frame = CGRectMake(9.0, 128.0, 96.0, 26.0);

        [cell.contentView addSubview:AddComment];

        UIImage *buttonAddComment = [UIImage imageNamed:@"addcomment.png"];

        [AddComment setBackgroundImage:buttonAddComment forState:UIControlStateNormal];

        [cell.contentView addSubview:AddComment]; 


    }

Cómo lograr esto, ¿podría por favor guiarme, donde estoy cometiendo un error.
