动态包装多个UIImageView周围的文本 [英] Dynamically wrapping text around multiple UIImageView

问题描述

在iPad应用程序页面中，用户可以手动输入文本，并在页面上放置图像/其他媒体，使文本在媒体间动态流动。例如，请参阅此图片。我也相信苹果说，他们没有使用未记录的API，任何开发人员可以理论上重新创建一个应用程序，如Pages。

如何在我的应用程序？

它似乎不像 CTFrame类有这样的包装与UIImageViews / UIWebViews / etc。的任何机制，我的Cocoa API的知识有点有限，所以我' c> path 参数，你可以用来包装对象周围的文本。

基本上，你必须构造一个路径包含要用文本填充的总面积，减去应该保留的面积（您的图像）。

In the iPad application Pages, the user can manually enter text and place images/other media on the page- making the text flow dynamically around the media. As an example, see this picture. I also believe Apple said they're not making any use of undocumented APIs, and any developer could theoretically recreate an app like Pages.

How can I recreate this within my app?

It doesn't seem like the CTFrame class has any mechanism for this kind of wrapping with UIImageViews/UIWebViews/etc., and my knowledge of the Cocoa APIs is a bit limited, so I'm not sure where to look.

解决方案

The CTFramesetterCreateFrame function has a path argument that you can use to wrap text around objects.

Basically, you will have to construct a path that contains the total area that is to be filled with text, subtracting the areas that should be left free (your images).
