  • @Kshitizyou can also achieve the functionality by using custom cells easily, but my experience says the smooth experience that you'd get by this method wouldn't be achievable by that one. – Vin Mar 04 '11 at 07:07

I have implemented a similar one by using tableview header. 

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 32)];
    UIButton *sectionButton = [UIButton buttonWithType:UIButtonTypeCustom];
    sectionButton.tag = section;
    sectionButton.frame = customView.frame;
    [sectionButton addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];

    UILabel *titleLabel = [[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 32)] autorelease];
    titleLabel.textAlignment = UITextAlignmentCenter;
    titleLabel.backgroundColor = [UIColor clearColor];
    titleLabel.font = [UIFont boldSystemFontOfSize:13];
    titleLabel.textColor = [UIColor whiteColor];

    NSString *tableHeader = @"table_header_down.png";
    switch (section) {
        case 0:
            titleLabel.text = @"Section1";
            tableHeader = showSection1 ? @"table_header_up.png" : @"table_header_down.png";
            break;
        case 1:
            titleLabel.text = @"Section2";
            tableHeader = showSection2 ? @"table_header_up.png" : @"table_header_down.png";
            break;
        case 2:
            titleLabel.text = @"Section3";
            tableHeader = showSection3 ? @"table_header_up.png" : @"table_header_down.png";
            break;
        case 3:
            titleLabel.text = @"Section4";
            tableHeader = showSection4 ? @"table_header_up.png" : @"table_header_down.png";
            break;
        default:
            break;
    }
    [sectionButton setImage:[UIImage imageNamed:tableHeader] forState:UIControlStateNormal];
    [customView addSubview:sectionButton];

    [customView addSubview:titleLabel];

    return [customView autorelease];
}

Then I loaded the cell accordingly to the boolean values corresponding to each section, number of rows returns 0 if Bool 0, and returns the count when Bool 1.

  • i am late now , but will definitely check out your solution tomorrow , thanx – Kshitiz Ghimire Mar 08 '11 at 11:58
  • also, I forget to mention one thing, you may need to have some more thing to do in number if rows in section method. Return zero, if the boolean variable corresponding to that section is zero. In the button pressed method, I am switching the flag of the section between 0 and 1. – Nithin Mar 15 '11 at 12:16

If you are an Apple developer, go to the WWDC videos and check out the advanced TableView video. It describes how to do exactly what you are asking about.
