how to change the content of table footer view while running

I want to toggle the buttons in viewForFooterInsection

i.e call the

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section

function again on button click.

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
	
		if(footerView == nil) {
			//allocate the view if it doesn't exist yet
			footerView  = [[UIView alloc] init];

	UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

			if (!favourite) {
				[button setTitle:@"Add to Favorites" forState:UIControlStateNormal];
				[button addTarget:self action:@selector(addFav:) forControlEvents:UIControlEventTouchUpInside];
				favourite=1;
				[tbldetail reloadData];
			}
			else {
				[button setTitle:@"Remove From Favorites" forState:UIControlStateNormal];
				[button addTarget:self action:@selector(removeFav:) forControlEvents:UIControlEventTouchUpInside];
				favourite=0;
			}
			[footerView addSubview:button];
}
return footerView;
}

You just need to keep a reference to the view object that you put in the footer. Then when the button gets pressed call a selector that will change the contents of the view, just like you've done. Finally call "setNeedsDisplay" on the view. That way the view will be re-drawn with your changes.
