在 Cocoa 中存储下载的文件 [英] Storing downloaded files in Cocoa

问题描述

我正在开发 Cocoa 应用程序，它需要 10.7+.所以，我很乐意使用新的闪亮 API.

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

我想要做的是从我们的后端服务器下载一些 MP3 和可能的一些 XML 数据，并将其存储在用户的 Mac 上.我很想将它存储在application.app"目录中，以及与应用程序捆绑在一起的初始资源.

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.

我可以这样做吗?在 application.app 中存储文件?

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

如果没有，存储附加数据的首选目录在哪里?

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

注意:它必须支持苹果的新沙盒工具.

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

(这是个好主意吗: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

这是 Apple 的 应用沙盒设计指南 并阅读容器目录和文件系统访问".目录~/Library/Container/com.yourcompany.yourappname/"及其子目录将仅是您的应用程序，因此在我看来，该目录将是您保存将从网络下载的内容的最佳位置.

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.
