UITextView w /语法高亮

问题描述

有Cocoa或Cocoa-Touch的通用库，解析器等，可以获取一大块文本，并进行正确的语法高亮？作为一个简单的例子，我想有一个UITextView具有C / C ++语法高亮。

解决方案

我编写了一个示例应用程序，语法高亮显示：

p>

不幸的是我的目标是一个可编辑的语法高亮编辑器，但是contentEditable被禁用（我已经提交了一个与苹果的错误报告;它是一个特征回归） p>

更新：示例应用程序在Apple提交时被拒绝;他们声称有限功能。我回答说，它是一个语法高亮的源代码查看器与Safari和应用程序文件共享集成，并有十几个'屁应用程序'在商店。没有进来; P

Is there a common library, parser, etc. for Cocoa or Cocoa-Touch that can take a chunk of text and do the proper syntax highlighting? As a simple example, I'd like to have a UITextView that has C/C++ syntax highlighting.

解决方案

I've coded up a bit of an example application that does syntax highlighting:

Unfortunately my goal was for an editable syntax highlighting editor, but with contentEditable disabled (I've filed a bug report with Apple; it's a feature regression) I was hooped.

Update: The sample app was rejected by Apple when I submitted it; they claimed "limited functionality". I replied, "it's a syntax highlighting source code viewer with Safari and application filesharing integration, and there are a dozen 'fart apps' on the store." Didn't get in. ;P
