在NSTextView中创建一些文本的超链接 [英] Create hyperlink to some text in NSTextView

问题描述

我可以使用链接面板创建一个超链接到NSTextView中的一些网址。或者我可以使用NSAttributedString的NSLinkAttributeName属性手动添加链接。

I can create a hyperlink to some url in an NSTextView using the "Link Panel". Or I can add a link manually using the NSLinkAttributeName attribute of NSAttributedString.

我不想制作一个超链接到一些外部url，但我想能够创建一个超链接到NSTextView中的一些文本。你知道如何在页面中你可以设置一些文本作为书签，然后你可以做一个超链接到那个书签？

I don't want to make a hyperlink to some external url though, I want to be able to create a hyperlink to some text within the NSTextView. Do you know how in Pages you can set some text as a Bookmark, and then you can make a hyperlink to that bookmark? Any ideas or examples of how to go about that?

推荐答案

我没有这样做，但是它像下面这样：

I haven't done this in a while so take this with a grain of salt but it goes something like:

1. 您需要为应用程序定义一个协议来处理URL。它将类似于myApplicationName：// aPath


2. 在应用程序 Info.plist 文件中添加 CFBundleURLTypes 键。


3. 编写应用程序代码以响应来自NSWorkspace的 openURL 。这意味着应用程序必须了解如何将URL样式路径转换为其文档中的特定位置。

1. You need to define a protocol for you app to handle URLs. It will look something like "myApplicationName://aPath"
2. In the apps Info.plistfile add the protocol under CFBundleURLTypes key.
3. Write code for the app to respond to openURL from NSWorkspace. This means the app will have to understand how to convert a URL style path to a specific location in one of its documents.

我认为处理URL路径的最佳方法是为每个文档分配一个UUID，然后为段落分配一个数字方案，句子。 URL最终如下所示： myApplicationName：// UUID / paragraphNumber / sentenceNumber / wordNumber 。或者，您可以插入隐藏文本以定义锚点，并只搜索该锚点。

I think the best method for handling the URL path is to assign a UUID to each document and then a numeric scheme to the paragraph and sentences. The URL ends up looking like: myApplicationName://UUID/paragraphNumber/sentenceNumber/wordNumber. Alternatively you can insert hidden text to define an anchor and just search for that anchor.
