Reloading tableView header in ios7

Question

How can I do it without reloading all table?

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

    UIView *header;

         


        

Answer 1

You have to reload the whole section to reload the header.

[self.tableView reloadSections:[NSIndexSet indexSetWithIndex:section] withRowAnimation: UITableViewRowAnimationAutomatic];

OR

You could grab a handle to the view and update it manually:

UIView *headerView = [self.tableView headerViewForSection:section];
//... update your view properties here
[headerView setNeedsDisplay];
[headerView setNeedsLayout];

Answer 2

You need to use -reloadSections:withRowAnimation:

So when you need to update your headers:

NSIndexSet *headers = [NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, [self.tableView numberOfSections])];
[self.tableView reloadSections:headers withRowAnimation:UITableViewRowAnimationAutomatic];

If you've only got one section (as you just mentioned in your updated question) you can just call

[self.tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationAutomatic];
