TableHeaderView.m

- (void)viewDidLayoutSubviews {
    [super viewDidLayoutSubviews];
    // Give system time to properly recalculate tableHeaderView height and update it
    // Otherwise wrong height appear on iOS 10
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        self.tableView.tableHeaderView = self.tableView.tableHeaderView;
    });
}
