将下载的文件存储在Cocoa中 [英] Storing downloaded files in Cocoa

问题描述

我正在开发一个Cocoa应用程序，它需要10.7+。所以，我会很乐意使用新的闪亮的API。

I am developing a Cocoa application, and it requires 10.7+. So, I will gladly use the new shiny APIs.

我想做的是从我们的后端服务器下载一些MP3和可能一些XML数据，它在用户的Mac上。我非常想将在内的application.app目录以及与应用程序捆绑的初始资源一起存储。

What I would like to do is download some MP3s and probably some XML data from our back-end server, and store it on the user's Mac. I would much like to store it within the "application.app" directory, alongside the initial resources that are bundled with the application.

是我做的？将文件存储在application.app中？

Can I do that? Store files within the application.app?

如果没有，在哪里存储附加数据的首选目录？

If not, where is the preferred directory to store the additional data?

NOTE: It must support apple's new sandboxing thingie.

（这是一个好主意：参考）

// save our buddy list to the user's home directory/Library/Preferences.
    [prefs writeToFile:[@"~/Library/Preferences/MiniMessage Client.plist"
                    stringByExpandingTildeInPath] atomically: TRUE];

推荐答案

这里是Apple的 App Sandbox设计指南，并阅读容器目录和文件系统访问。目录〜/ Library / Container / com.yourcompany.yourappname /和它的子目录将是你的应用程序，所以在我看来，该目录将是你最好的地方，保存你从网上下载的东西。

Here's Apple's App Sandbox Design Guide and read the "Container Directories and File System Access". The directory "~/Library/Container/com.yourcompany.yourappname/" and it's subdirectories will be your Apps only, so seems to me that that directory would be your best place of saving the things you'll be downloading from the web.
