iOS Dropbox API - Re-Authenticating (Error 401)

Question

I've been having issues with my iOS App using Dropbox. It used to run with the Dropbox Core API perfectly fine, with no problems uploading a file, but now it'll show me an error 401. I've seen everywhere that all I need is to re-authenticate. Sorry if this question sounds dumb, but what is meant by re-authentication here and how do I do it?

Answer 1

您可能需要再次登录Dropbox。

Answer 2

For re-authentication first of all unlink your session using below code.

              [[DBSession sharedSession] unlinkAll];

hope it will work for you @Oscar.
