下拉刷新时UITableView的section headerView冲突的解决

1、如果选择不让HeaderView悬浮

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {  

CGFloat sectionHeaderHeight = 40;  

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);  

}

}

2、如果选择让HederView悬浮

if scrollView.isEqual(scheduleTableView){

   let sectionHeaderHeight: CGFloat = 44;

  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 = UIEdgeInsetsZero

          }

}

处理完成以后，然后

strongSelf.scheduleTableView.scrollToRowAtIndexPath(indexArray.index, atScrollPosition: .Middle, animated: false) 滚动到指定行，完成效果
