Documentation/Tutorials for integrating Dropbox in an iOS app (not written in Swift)

Hi Joe, we don't currently have an official Objective-C SDK, tutorial, or documentation for API v2, but it is something we're planning. I'll be sure to pass this along as feedback as well.

Also, note that both API v1 and v2 are currently supported. While API v2 is preferred, API v1 a.k.a. the Core API hasn't been deprecated, so you can use whichever you want. (It's just the Sync/Datastores SDK/API that are no longer supported.)

Thanks, Gregory. Our app is currently using the Sync SDK to read and write Dropbox files. The website says...

"Since the Sync SDK is built on the Core API, existing apps will continue to work, but we encourage developers to move to one of the Core SDKs as soon as possible."

Just to be clear, our iOS app will continue to work with our existing Sync SDK code. We do not need to upgrade our app to V2 anytime soon, correct?

If so, we're going to wait until support for Objective-C is added before we upgrade our app to support V2.

That's correct, we haven't announced any timeline for deprecating the Core API, so while we recommend moving off of the Sync SDK, it should continue working.

Greg: 

Since Datastores are included within the Sync API SDK. Will they continue to work? along with the Sync API SDK (v1)? Or is that aspect of Sync SDK stop working on April 1st 2016?

Raheel, the Datastore API will be disabled at the end of April, so any datastores syncing functionality, including in the Sync/Datastores SDK, will stop working then.

The official Objective-C SDK for API v2 has been released here:
