如何将文件保存到 iOS' Library/NoCloud 文件夹？
How to save a file to iOS' Library/NoCloud folder?
我正在使用 Cordova 开发一个应使用 Phonegap 的插件内容同步 (https://github.com/phonegap/phonegap-plugin-contentsync) 下载文件的应用程序。
我可以将文件下载到我的设备，但我需要将我的文件下载到 /Library/NoCloud 文件夹。
在我的 config.xml 中，我设置了以下内容：
<preference name="iosPersistentFileLocation" value="Library" />
<preference name="BackupWebStorage" value="none" />
开始下载时，我还在控制台中看到一些奇怪的东西。首先它引用 NoCloud 文件夹，但下载后，它似乎将我的文件存储在 Library 文件夹中...
这是我的 Xcode 控制台：

有人知道我可能做错了什么吗？
我建议使用 cordova-plugin-file 而不是 phonegap-plugin-contentsync，因为前者会将文件写入 NoCloud。
