I took shtefane's answer and improved on it. Enter your own cellWidth and cellPadding values.

- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView
                     withVelocity:(CGPoint)velocity
              targetContentOffset:(inout CGPoint *)targetContentOffset
{
    CGFloat cellWidth = self.cellWidth;
    CGFloat cellPadding = 9;

    NSInteger page = (scrollView.contentOffset.x - cellWidth / 2) / (cellWidth + cellPadding) + 1;

    if (velocity.x > 0) page++;
    if (velocity.x < 0) page--;
    page = MAX(page,0);

    CGFloat newOffset = page * (cellWidth + cellPadding);
    targetContentOffset->x = newOffset;
}
