cocoa - 我应该如何使用帮助 : URL in a Snow Leopard . 帮助包？

Question

我正在为我的应用程序编写帮助手册。根据需要，我的应用程序的 info.plist 中有 CFBundleHelpBookName 和 CFBundleHelpBookFolder 键，并且我正在使用新的 Snow Leopard .help bundle 格式作为帮助手册。 Rehearsals.help/Contents/Info.plist 中的各个键均按照 Apple Help Programming Guide 填充。 。正如预期的那样，当用户从“帮助”菜单中选择“排练帮助”时，我的帮助书的索引页(在适当的本地化版本中，目前只有英语)将在帮助查看器中打开。

但是， bundle 中实际上(当前)有两个 HTML 文件:index.html 和 support.html。据我了解，如果我将命名 anchor 放在一个文件中，如下所示:

<a name="support"></a>

然后我可以从其他文件链接到它，如下所示:

<a href="help:anchor=support bookID=info.thaesofereode.Rehearsals.help">Support</a>

但是这不起作用。也没有:

<a href="help:anchor=support">Support</a>

帮助查看器显示一个工作表，显示“帮助查看器无法打开此内容。”，如果我在帮助查看器和 helpd 中打开调试日志记录，我会看到以下内容:

如何在 Snow Leopard 帮助包中正确使用 help: URL？ (不用说，我知道使用相对文件 URL 的解决方法，并且可行，但我希望获得帮助 anchor 来提供上下文帮助和应用程序内的链接。)

Answer 1

事实证明，这些 anchor 和 URL 是正确的，helpd 会自动索引内容，但它会维护积极的缓存。如果更新帮助手册时没有更改版本号，则它不会扫描新的 anchor 。

rm -rf ~/Library/Caches/com.apple.help*
killall helpd
