Essentially, all you have to do is add a boolean UIFileSharingEnabled (YES) key to your app's info.plist. Then the documents added through iTunes will be available in your app's documents directory.

本质上，你所要做的就是为你的app的info.plist添加一个布尔UIFileSharingEnabled (YES)键。然后，通过iTunes添加的文档将可以在应用程序的文档目录中找到。

UIFileSharingEnabled (Boolean - iOS) specifies whether the application shares files through iTunes. If this key is YES, the application shares files. If it is not present or is NO, the application does not share files. Applications must put any files they want to share with the user in their /Documents directory, where is the path to the application’s home directory.

UIFileSharingEnabled (Boolean - iOS)指定应用程序是否通过iTunes共享文件。如果这个键是YES，应用程序共享文件。如果不存在或不存在，则应用程序不共享文件。应用程序必须将想要与用户共享的任何文件放在其/文档目录中，其中是应用程序的主目录的路径。

In iTunes, the user can access an application’s shared files from the File Sharing section of the Apps tab for the selected device. From this tab, users can add and remove files from the directory.

在iTunes中，用户可以从Apps选项卡的文件共享部分访问应用程序的共享文件。从这个选项卡，用户可以添加和删除目录中的文件。

This key is supported in iOS 3.2 and later.

这个键在ios3.2和以后的版本中都得到了支持。
