UIScrollView scroll up show like pageControl

Question

I have a UIScrollView, on this view, I add more UIView, like this

enter image description here

When I scroll up or down, I want the UIView full display, the effect like UIPageControl, but I just want change one cell or more, not a page.

How could I do it? Thanks.

Edit

The effect like this here

But I want use to control all the UIView, and scroll up and down just one or more UIView.

In my `UIView` have another thing to do, so I use `UIScrollView` — lighter, Jan 16 '14 at 10:34

how about implementing a snap functionality for your tableview?. This is much more useful then the way you are doing now. — Totumus Maximus, Jan 16 '14 at 16:01

I found the answer.

The answer reference [this]

Use UIScrollView can achieve this effect.

Edit

In order scroll accuracy, I use fmodf. This can reference [this].

This is my code.

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    float toMove = fmodf(scrollView.contentOffset.y, _cellHeight);

    if(toMove < _cellHeight / 2)
        [scrollView setContentOffset:CGPointMake(0, scrollView.contentOffset.y - toMove) animated:YES];
    else
        [scrollView setContentOffset:CGPointMake(0, scrollView.contentOffset.y + (_cellHeight - toMove)) animated:YES];
}

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate
{
    [self scrollViewDidEndDecelerating:scrollView];
}
