CFBundleTypeIconFile指定文件扩展名不显示的图标 [英] CFBundleTypeIconFile Icon not showing for given file extension

问题描述

我有以下Info.plist为我的应用程序，问题是文件我保存与扩展myapp似乎并没有拾起我的MyApp图标，我已经从一个图标集创建（应用程序正确使用图标）所以猜测在plist有错误。

I have the following Info.plist for my application, the problem is files i save with the extension myapp do not seem to pick up on my MyApp icon which i have created from an icon set (application correctly uses icon) so guessing there is something wrong in the plist.

我假设如果我在某些时候运行我的应用程序时工作，我保存的文档将突然显示给定的图标。

I am assuming if I got this working when running my application at some point documents that I have save will suddenly show with the given icon.

在这种情况下，文档是从一组基于NSCoder的类保存的。点击这些文件也会打开我的应用程序并加载文件正确，所以困惑我缺少的图标来显示在文件....

Incase this matters, the document is saved from a set of NSCoder based classes. Clicking these documents also opens my application and loads the file correctly, so confused what I am missing to get Icon to show on the files....

推荐答案

结果系统必须缓存了一个旧的副本plist当我最初创建我的应用程序。所有需要的是重建启动服务数据库。

Turns out the system must have cached a old copy of the plist when I initially created my application. All that was needed was to rebuild the launch services database.

我使用lsregister命令，如下所示：

I used the lsregister command as documented here...

重新运行应用程序，bingo文档现在有相关的图标。

Rerun the application and bingo the documents now have the respective icon associated.
