macos - 获取突出显示的文本

Question

我正在开发一个应用程序，我需要在应用程序外部获取用户当前突出显示的文本，有什么方法可以做到这一点吗？

我了解到我可以注册为服务，但我不想这样做。

Answer 1

I'm developing an application in which I need to get the current highlighted text of the user outside my application, is there any way to do this?

I've read that I can register as a service but I don't want to do that.

你真的应该这样做。这是正确的方法。

I don't want to force the user to do a copy, I only want him to highlight the text.

(或者她。)

这就是服务的工作原理:选择某些内容(通常是文本)，然后调用服务。

… I wan't to be able to get the highlighted text with the press of a shortcut.

你也可以这样做。

您的服务字典应如下所示:

<!--in Info.plist-->
<key>NSServices</key>
<dict>
    <key>NSMenuItem</key>
    <dict>
        <key>default</key>
        <string>ROT-13</string>
    </dict>

    <key>NSKeyEquivalent</key>
    <dict>
        <key>default</key>
        <!-- ⌘ is implicit, and an uppercase letter likewise implies shift -->
        <!-- Thus, this is ⌘-shift-e -->
        <string>E</string>
    </dict>

    <key>NSRequiredContext</key>
    <dict>
        <key>NSServiceCategory</key>
        <string>public.text</string>
    </dict>

    <key>NSSendTypes</key>
    <array>
        <string>NSStringPboardType</string>
    </array>

    ⋮
</dict>
