Question

I’m trying to add a button when a row is selected in UITableView and also remove it when row is tapped second time, i don’t want custom UITableViewCell.

Any suggestion or sample code will be appreciated.

code i’ve tried:
in cellForRowAtIndexPath method

if(cell.selected == YES){

                UITextField* numOfBottles =[[UITextField alloc] initWithFrame:CGRectMake(240,9.0f,50, 25)];
                numOfBottles.tag = indexPath.row;

                [numOfBottles setBorderStyle:UITextBorderStyleNone];
                [numOfBottles setBackgroundColor:[UIColor clearColor]];
                [numOfBottles setTextColor:[UIColor whiteColor]];
                [numOfBottles setTextAlignment:UITextAlignmentLeft];
                [numOfBottles setBackground:[UIImage imageNamed:@"blue_dropdown_normal.png"]];
                [numOfBottles setFont:[UIFont systemFontOfSize:16.0f]];
                [numOfBottles setDelegate:self];

                NSString* quantity = [[NSString alloc] initWithString:[subtotalObj.qtyArray objectAtIndex:(indexPath.row - 1)]];

                [numOfBottles setText:quantity];
                [numOfBottles setTextAlignment:UITextAlignmentCenter];
                [numOfBottles setBackgroundColor:[UIColor whiteColor]];
                numOfBottles.keyboardType = UIKeyboardTypeDefault;
               // numOfBottles.tag = indexPath.row;
                [cell.contentView addSubview:numOfBottles];
                [numOfBottles release];
            }

and in didSelectRowAtIndexPath method

[tableView reloadData];

But still button(textfield with background image) is not rendered.

I think the best way is to use a UITableViewCell subclass.
But you can use my answer on another question to make your TableView rerender and place a button in your cell.

- (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 == selectedRow){ // if your criteria where met
      //add your button
    }

     return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    //do your select things here
  selectedRow = indexPath.row; //where selectedRow is a class variable
  [self.tableView reloadData]; // rerenders the tableview

}
