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
