[ios] How to enable file sharing for my app?

I have an image editing app where users can apply effects to photos. How could I enable it so that users can see my app in iTunes in the File Sharing tab and then just drag+drop photos to the app?

Some of the eBook readers like Stanza works like this and it would be a cool option. Maybe someone can point out a tutorial or resource that talks about how to enable and use this technique.

If you editing info.plist directly, below should help you, don't key in "YES" as string below:

<key>UIFileSharingEnabled</key>
<string>YES</string>

You should use this:

<key>UIFileSharingEnabled</key>
<true/>

If you find by alphabet in plist, it should be "Application supports iTunes file sharing".

New XCode 7 will only require 'UIFileSharingEnabled' key in Info.plist. 'CFBundleDisplayName' is not required any more.

One more hint: do not only modify the Info.plist of the 'tests' target. The main app and the 'tests' have different Info.plist.

In Xcode 8.3.3 add new row in .plist with true value

Application supports iTunes file sharing

Maybe it's obvious for you guys but I scratched my head for a while because the folder didn't show up in the files app. I actually needed to store something in the folder. you could achieve this by

• saving some files into your document directory of the app
• move something from iCloud Drive to your app (in the move dialog the folder will show up). As soon as there are no files in your folder anymore, it's gonna disappear from the "on my iPad tab".

According to apple doc:

File-Sharing Support
File-sharing support lets apps make user data files available in iTunes 9.1 and later. An app that declares its support for file sharing makes the contents of its /Documents directory available to the user. The user can then move files in and out of this directory as needed from iTunes. This feature does not allow your app to share files with other apps on the same device; that behavior requires the pasteboard or a document interaction controller object.

To enable file sharing for your app, do the following:

1. Add the UIFileSharingEnabled key to your app’s Info.plist file, and set the value of the key to YES. (The actual key name is "Application supports iTunes file sharing")

2. Put whatever files you want to share in your app’s Documents directory.
   

3. When the device is plugged into the user’s computer, iTunes displays a File Sharing section in the Apps tab of the selected device.
   

4. The user can add files to this directory or move files to the desktop.
   

Apps that support file sharing should be able to recognize when files have been added to the Documents directory and respond appropriately. For example, your app might make the contents of any new files available from its interface. You should never present the user with the list of files in this directory and ask them to decide what to do with those files.
