How to animate the height change of an section header in UITableView?

Question

I\'ve implemented this method to return the section header height. However, when the height for the section changes, it happens immediately without animation.

Answer 1

I'm not 100% sure this will work for a table header but it works for table rows so it's worth a shot. I have an instance variable headerHeight initially set to 44.0 and I change it as so:

- (void)changeHeight {
    [self.tableView beginUpdates];
    headerHeight = 88.0;
    [self.tableView endUpdates];
}

In my code I return the headerHeight in heightForRowAtIndexPath but you can try it in heightForHeaderInSection:

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return headerHeight;
}
