问如何构建连续视差滚动/表视图？

EN

// create a topImageView and bottomImageView.
// set contentMode UIViewContentModeScaleAspectFill
// set clipsToBounds = YES
// place them both on self.view (bottom first)
// create a scrollView with a clear background.
// place it on the self.view.
// get the array of images.
// set the scrollView.contentSize = number of images * height of scrollView.

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    CGFloat percentageOffset = scrollView.contentOffset.y / CGRectGetHeight(scrollView.frame);

    NSInteger topPage = floorf(percentageOffset);
    CGFloat topPageOffset = percentageOffset - topPage;

    // make sure that you're not going outside of the index bounds first!!!!

    self.topImageView.image = self.images[topPage];
    self.bottomImageView.image = self.images[topPage + 1];

    // move the top image view so it looks like you are scrolling it.
    self.topImageView.frame = CGRectOffset(self.view.bounds, -self.view.bounds.height * topPageOffset, 0);
