问题描述

我将 pagingEnabled 设置为 YES 的 UIScrollView，并以编程方式将其内容滚动到底部:

I have the UIScrollView with pagingEnabled set to YES, and programmatically scroll its content to bottom:

CGPoint contentOffset = scrollView.contentOffset;
contentOffset.y = scrollView.contentSize.height - scrollView.frame.size.height;
[scrollView setContentOffset:contentOffset animated:YES];

它滚动成功，但在那之后，单击它的内容会向上滚动以抵消它在向下滚动之前的偏移量.仅当我以编程方式将 scrollView 的内容滚动到底部然后点击时才会发生这种情况.当我滚动到任何其他偏移量然后点击时，什么都没有发生.

it scrolls successfully, but after that, on single tap its content scrolls up to offset that it has just before it scrolls down. That happens only when I programmaticaly scroll scrollView's content to bottom and then tap. When I scroll to any other offset and then tap, nothing is happened.

这绝对不是我想要的.应该如何解决?

That's definitely not what I'd like to get. How that should be fixed?

提前非常感谢！
