Hide sections of a Static TableView

Question

I've found this tutorial which hides a section of a Static TableView: http://code-ninja.org/blog/2012/02/29/ios-quick-tip-programmatically-hiding-sections-of-a-uitableview-with-static-cells/

It works great but only without modifying it, if I add a section or a row, it works bad. I'm a beginner and I'm not able to modify it, can somebody help me hiding more than one section?

Thank you so much!

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {            
    if (section == 2 && _hideTableSection) {
        //header height for selected section
        return 0.1; 
    } else {
        //keeps all other Headers unaltered 
        return [super tableView:tableView heightForHeaderInSection:section]; 
    }  
}

-(CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {        
    if (section == 2 && _hideTableSection) {
        //header height for selected section
        return 0.1; 
    } else {
        // keeps all other footers unaltered
        return [super tableView:tableView heightForFooterInSection:section]; 
    } 
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    if (section == 1) { //Index number of interested section
        if (hideTableSection) {
            return 0; //number of row in section when you click on hide
        } else {
            return 2; //number of row in section when you click on show (if it's higher than rows in Storyboard, app will crash)
        }
    } else {
        return [super tableView:tableView numberOfRowsInSection:section]; //keeps inalterate all other rows 
    }    
}
