iOS 8 storage provider app extension UIActivityController or UIDocumentInteractionController?

We are writing a new app, and create an audio file that we want to allow users to share out to Dropbox, email, Airdrop, etc.

When I put a plain UIActivityController up, which I supply with an NSURL to the audio file all that shows is Mail, Message and Airdrop. I have the latest Dropbox on the iPhone, and understand that the Dropbox app has a storage provider app extension. Yet nothing shows up.

Do I have to use the UIDocumentInteractionController to get Dropbox to show? I thought it would automatically show on the UIActivityController panel, as Dropbox is installed.

Thanks for any tips.

If you're looking for the new iOS 8 document picker extension, I believe you want to use UIDocumentPickerViewController, for which the Dropbox app supports the modes:

UIDocumentPickerModeImport
UIDocumentPickerModeExportToService

You should support the Open mode too! :! (

I just wanted to follow up to update this thread about the current state of this functionality.

On iOS 9 and 10, we support Document Picker modes "Import" and "Export", but not modes "Open" and "Move".

On iOS 11, we support the new File Provider extension (which is iOS 11 only). Our general recommendation is for people to update to iOS 11 and the latest version of the Dropbox app. You can find information on the functionality provided by the Dropbox File Provider extension here: https://www.dropbox.com/help/mobile/ios-files-app
