核心代码
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
CGFloat sectionHeaderHeight = sectionHead.height; // 区头高度
if (scrollView.contentOffset.y<=sectionHeaderHeight&&scrollView.contentOffset.y>=){
scrollView.contentInset= UIEdgeInsetsMake(-scrollView.contentOffset.y,,,);
} else if(
scrollView.contentOffset.y>=sectionHeaderHeight) {
scrollView.contentInset= UIEdgeInsetsMake(-sectionHeaderHeight,,,);
}
}
