Enable direct transfer from iWork apps to my app

I am investigating the possibilities of making an app that can handle iWork's apps documents (Pages, Numbers, Keynote). I have made the app and have registered the Document types, but this only gets me as far as supporting Open In from other apps that implements the UIDocumentInteractionController.

As far as I have been able to gather - The only possibility available currently is to implement a WebDAV service, and using it to sync the documents.

Filesharing from pages

Another possibility is to transfer using iTunes

Sharing using iTunes

My conclusion: no direct transfer.

None of these 开发者_如何学Pythonoptions appeal to me, but the most reasonable is to implement a WebDAV service, like DropBox.

So, my question is - Does anyone have experience with enabling document transfers, in a direct manner - If so, how. If not, am I correct in saying that the WebDAV path is feasible?

Thanks.

Direct app-to-app transfer will not work if the other app(s) do not cooperate with you. You would have to get Apple to offer an "Open In…" command in their iWork apps that uses UIDocumentInteractionController to make it work.
