Iphone app to be used like usb storage.

I'm wanting to access applications storage via iTunes, where i can save documents and be available in my app.

I have looked all over google, but without a specific name i don't know what I'm looking for.

Some of the app's that use this functionality are VLC & usb Disk; there are many many 开发者_如何学运维more.

So I'm asking what the API is called and if anyone knows of sample code or an example.

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.

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.

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.

This key is supported in iOS 3.2 and later.
