UIScrollView - 启用了分页，可以“更改”页宽？ [英] UIScrollView - with paging enabled, can I "change" the page width?

问题描述

有一个滚动视图（将pagingEnabled设置为YES）的最简单的方法是将页面宽度设置为非滚动视图的边界？

让我给一个例子。假设我有一个滚动视图有10项，每个150像素宽，我的滚动视图是300像素宽。如果我从视图1和视图2开始向右滚动，我想要下一个页面显示项目2和3.如果我再向右滚动一页，我会看到项目3和4.

有没有人这样做？

解决方案

Alexander Repty刚刚在博客中介绍了这个主题： http://blog.proculo.de/archives/180-Paging-enabled-UIScrollView -With-Previews.html 。简短的答案：这不是简单的只是改变页面的宽度，但它不是太难。

What's the simplest way to have a scroll view (with pagingEnabled set to YES) have a page width set to something other than the scroll view's bounds?

Let me give an example. Suppose I have a scroll view with 10 items, each 150 pixels wide, and my scroll view is 300 pixels wide. If I start with views 1 and 2 visible and scroll horizontally to the right, I want the next "page" to show items 2 and 3. If I scroll one more page to the right, I would see items 3 and 4.

Has anyone done this? If not, what strategy would you use?

解决方案

Alexander Repty just blogged about this very topic: http://blog.proculo.de/archives/180-Paging-enabled-UIScrollView-With-Previews.html. Short answer: it's not as simple as just changing the width of the 'page', but it's not too hard.
