Add double the number of sections you actually have. Let even number of sections only have section headers, while odd number section should have only rows without section headers. 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return double the number of sections.
return ([_arrSection count]*2);
}

and..

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
//Even Sections will have only header and no rows 
if(section%2 == 0)
    return 0;

//Number of rows return only is the section is expanded else return 0
return [arrRowsForSpecificSection count];
}

and...

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
//Odd sections will have no header
if(section%2 == 1)
    return 0;

//for even sections
return HEIGHT_FOR_SECTION_HEADER;
}

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{

//Odd section will have no header
if(section%2 == 1)
    return NULL;
//even section will have header
return Header_View;
}

Thus at run time it gives an impression that it is the header of current section that scrolls without getting fixed at the top. Smooth animation!!!! Cheers
