tableView的plain样式的headerView的上拉过程中悬停解决方法

//去掉UItableview headerview黏性(sticky) 去掉header的浮动效果

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

if (scrollView == self.tableView)

{

CGFloat sectionHeaderHeight = 100; //sectionHeaderHeight

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);

}

}

}
