tableview的header随tableview一起滚动

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

if(scrollView ==self.myTableView)

{

CGFloat sectionHeaderHeight = YOUR_HEIGHT;

if(scrollView.contentOffset.y<=sectionHeaderHeight&&scrollView.contentOffset.y>=0) {

scrollView.contentInset= UIEdgeInsetsMake(-scrollView.contentOffset.y,0,0,0);

}elseif(scrollView.contentOffset.y>=sectionHeaderHeight) {

scrollView.contentInset= UIEdgeInsetsMake(-sectionHeaderHeight,0,0,0);

}

}

}
