在这个方法里,判断
-(void)scrollViewDidScroll:(UIScrollView*)scrollView {
if(scrollView ==self.MeTableView){
CGFloat sectionHeaderHeight =200; // 200 自定义header 的高度
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);
}
}
}
