如何在沙盒应用程序中获取/Users/username/Downloads路径? [英] how to get /Users/username/Downloads path in a sandboxed app?

问题描述

我所做的是将 com.apple.security.files.downloads.read-write 设置为 true ，并查看了与Apple Sandbox相关的文档，但我不知道如何获取下载文件夹路径，我仍然得到的是这样的容器路径:/Users/username/Library/Containers/com.errpro.Snell/Data/Downloads ，我使用的方法是 NSSearchPathForDirectoriesInDomains .我见过有人使用 getpwent 来获取路径，但似乎不合适.任何帮助将不胜感激.

what I've done is setup the com.apple.security.files.downloads.read-write to true, and have looked up the Apple Sandbox related docs, but I can't figure out how to get the downloads folder path, what I get is still container path like this: /Users/username/Library/Containers/com.errpro.Snell/Data/Downloads , the method I use is NSSearchPathForDirectoriesInDomains. I've seen someone use getpwent to get the path, but seems not appropriate. Any help would be appreciated.

推荐答案

您应使用URLForDirectory方法.此方法找到当前用户的名称并将其插入URL路径.

You should use the method URLForDirectory. This method find the name of the current user and insert it in the URL path.

NSFileManager       *fm = [NSFileManager defaultManager];
NSURL               *downloadsURL;  

downloadsURL = [fm URLForDirectory:NSDownloadsDirectory
                   inDomain:NSUserDomainMask appropriateForURL:nil
                   create:YES error:nil];
