customize UITableView Header Section at run time

I have set header back ground using the code below but I want to change the color of header back again on run time when I click on the button that is added as a subview on the header. please provide me code, thanks in advance :)

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

    header = [[UIView alloc]initWithFrame:CGRectMake(0, 0, _tableView.bounds.size.width, 50)];
 header.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"homeCellHeaderBackGround.png"]];

    UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(10, 10, 100, 30)];
    label.text = _array[section][@"name"];
    label.textColor = [UIColor whiteColor];


    [header addSubview:label];


    UIButton *button = [[UIButton alloc]initWithFrame:CGRectMake(230, 10, 70, 35)];
    [button addTarget:self action:@selector(onExpandButton:) forControlEvents:UIControlEventTouchUpInside];
    //[button setTitle:@"Expand" forState:UIControlStateNormal];
    [button setTag:section];

    [header addSubview:button];

    return header;
}

You can change the background color of the section header by following code:

- (IBAction)onExpandButton:(id)sender {
   UIView *header = ((UIButton *)sender).superView;
   header.backgroundColor = <Whatever UIColor you like>;
   ...
}

You can modify it in run time by:

first:

you can declare a global variable/propery like:

@property (nonatomic) UIView *tableHeader;

and set it under -(void)viewDidLoad

like

self.tableView.tableHeaderView = self.tableHeader;

or using the delagate:

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
   return self.tableHeader;
}

and modify it anywhere you like, but dont forget to reload you table section header, probably [tableView reloadSections:NSIndexSet withRowAnimation:UITableViewRowAnimation]; will do.

But

In your case you can retreive/get the tableHeader made inside the delegate:

-(UIView *)tableView:tableView viewForHeaderInSection:section

by

UIView *tableHeaderView = [self tableView:yourTableView viewForHeaderInSection:yourSection];

then modify tableHeaderView..

or simply reassign tableHeader by:

yourTableView.tableHeaderView = tableHeaderView;

your by using header alone, since as i can see it's a global variable.. change/update it directly like:

header.backgroundColor = [UIColor yourNewColor];

hope i've helped you.. happy coding, cheers..

-(IBAction)onExpandButton:(UIButton *)sender
{
    UIView *tmpView = [self.YourTableViewName headerViewForSection:sender.tag];
    tmpView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"homeCellHeaderBackGround.png"]];
}

-You got the view from your table view header for section method. After you can set your image view on view.
