I ran this with vigorouscoding's code. However that code did not consider sectionInset.

So I changed this code for vertical scroll

origin.y = MIN(
              MAX(contentOffset.y, (CGRectGetMinY(firstCellAttrs.frame) - headerHeight)),
              (CGRectGetMaxY(lastCellAttrs.frame) - headerHeight)
           );

origin.y = MIN(
           MAX(contentOffset.y, (CGRectGetMinY(firstCellAttrs.frame) - headerHeight - self.sectionInset.top)),
           (CGRectGetMaxY(lastCellAttrs.frame) - headerHeight + self.sectionInset.bottom)
           );

If you guys want code for horizontal scroll, refer to code aove.
