copied!<p>You have to make your own custom header row and put that as the first row of each section. Subclassing the <code>UITableView</code> or the headers that are already there will be a pain. Based on the way they work now, I am not sure you can easily get actions out of them. You could set up a cell to LOOK like a header, and setup the <code>tableView:didSelectRowAtIndexPath</code> to manually expand or collapse the section it is in.</p> <p>I'd store an array of booleans corresponding the the "expended" value of each of your sections. Then you could have the <code>tableView:didSelectRowAtIndexPath</code> on each of your custom header rows toggle this value and then reload that specific section.</p> <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.row == 0) { ///it's the first row of any section so it would be your custom section header ///put in your code to toggle your boolean value here mybooleans[indexPath.section] = !mybooleans[indexPath.section]; ///reload this section [self.tableView reloadSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationFade]; } } </code></pre> <p>Then set <code>numberOfRowsInSection</code> to check the <code>mybooleans</code> value and return 1 if the section isn't expanded, or 1+ the number of items in the section if it is expanded.</p> <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (mybooleans[section]) { ///we want the number of people plus the header cell return [self numberOfPeopleInGroup:section] + 1; } else { ///we just want the header cell return 1; } } </code></pre> <p>Also, you will need to update <code>cellForRowAtIndexPath</code> to return a custom header cell for the first row in any section.</p>
