我正在尝试使用服务创建 Finder 上下文菜单项（如此处所述：为 Finder.app 编写雪豹服务）

但是，我希望仅为文件夹添加上下文菜单条目。每当我将以下代码放入 .plist 文件中时：

<key>NSServices</key>
<array>
    <dict>
        <key>NSMenuItem</key>
        <dict>
            <key>default</key>
            <string>Service Handling Demo</string>
        </dict>
        <key>NSMessage</key>
        <string>handleServices</string> <!-- This specifies the selector -->
        <key>NSPortName</key>
        <string>Tmp</string>       <!-- This is the name of the app -->
        <key>NSSendTypes</key>
        <array>
            <string>NSFilenamesPboardType</string>
        </array>
    </dict>
</array>

一切正常，我可以在“服务”选项卡（键盘快捷键）中选择我的服务并运行它。

但是，如果我尝试将服务用于文件夹：

<key>NSServices</key>
<array>
    <dict>
        <key>NSMenuItem</key>
        <dict>
            <key>default</key>
            <string>Service Handling Demo</string>
        </dict>
        <key>NSMessage</key>
        <string>handleServices</string> <!-- This specifies the selector -->
        <key>NSPortName</key>
        <string>Tmp</string>       <!-- This is the name of the app -->
        <key>NSSendFileTypes</key>
        <array>
            <string>public.directory</string>
        </array>
        <key>NSSendTypes</key>
        <array>
            <string>NSStringPboardType</string>
        </array>
    </dict>
</array>

该服务没有出现在键盘快捷方式的菜单中，当然在查找器中也不可见......

我错过了什么？

Add the following code to the .plist:

<key>NSServices</key>
<array>        
    <dict>
        <key>NSMenuItem</key>
        <dict>
            <key>default</key>
            <string>Folder Handling Demo</string>
        </dict>
        <key>NSMessage</key>
        <string>handleServices</string> <!-- This specifies the selector -->
        <key>NSPortName</key>
        <string>Tmp</string>       <!-- This is the name of the app -->

        <!-- Here we're limiting where the service will appear. -->
        <key>NSRequiredContext</key>
        <dict>
            <key>NSTextContent</key>
            <string>FilePath</string>
        </dict>
        <!-- This service is only really useful from the Finder. So
         we want the finder only to send us the URI "public.directory"
         which *will* include packages (on the off-chance you want to
         see the full package directory name) -->
        <key>NSSendFileTypes</key>
        <array>
            <!-- Check out "System-Declared Uniform Type Identifiers"
             in the Apple documentation for the various UTI types.
             In this example, all we want is a directory, which is
             a super-type to other types (e.g. public.folder) -->
            <string>public.folder</string>
        </array>
    </dict>

And the service will appear under "Files and Folders" group in the services list (keyboard shortcuts tab).
