推荐答案

文件目录不会被覆盖当您更新应用程序时，只要您的数据在版本之间兼容，您就不必执行任何特殊操作。

The Documents directory is not overwritten when you update an app so as long as your data is compatible between versions, you shouldn't have to do anything special.

或者，对于开发人员，Xcode的管理器允许您轻松提取应用文档目录的内容。

Alternatively, for developers, Xcode's Organizer allows you to extract the contents of an apps Documents directory easily.
