Apple made a generic solution for this on iOS and OS X. Document
Provider Extensions (OK, new OS versions only).
https://developer.apple.com/library/prerelease/ios/documentation/General/Conceptual/ExtensibilityPG/FileProvider.html#//apple_ref/doc/uid/TP40014214-CH18-SW1

If you want to read and write files from/to cloud storage then there's
single interface and the device only shows providers that the user has
installed/configured.

The latter part you obviously can't get without being the OS provider
and having providers write Extensions to tell the system they offer file
storage. For Apple platforms at least it would make sense to mimic the
interface as far as possible though, assuming you don't just want to
wrap what they've already done.
