iphone - UITableView tap to deselect cell

Question

I have a UITableViewCell that is selected when tapped. During this selected state, if the user taps the cell again, I want the cell to deselect.

I can't find any of the delegate calls being hit. Any ideas how to implement this? Is it really going to be a gesture recognizer?

You can actually do this using the delegate method willSelectRowAtIndexPath:

- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if ([cell isSelected]) {
        // Deselect manually.
        [tableView.delegate tableView:tableView willDeselectRowAtIndexPath:indexPath];
        [tableView deselectRowAtIndexPath:indexPath animated:YES];
        [tableView.delegate tableView:tableView didDeselectRowAtIndexPath:indexPath];

        return nil;
    }

    return indexPath;
}

Note that deselectRowAtIndexPath: won't call the delegate methods automatically, so you need to make those calls manually.
