在UITableViewStylePlain情況下sectionHeader可以與tableview一起滑動的解決方法

-(void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    CGFloat sectionHeaderHeight = 20;
    if (scrollView.contentOffset.y <= sectionHeaderHeight&&scrollView.contentOffset.y > 0) {
        scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);
    }else if (scrollView.contentOffset.y >= sectionHeaderHeight){
        scrollView.contentInset = UIEdgeInsetsMake(-sectionHeaderHeight, 0, 0, 0);
    }
}

在 -(void)scrollViewDidScroll:(UIScrollView *)scrollView方法中添加上訴代碼即可
