uploadURL unrecognized selector

I'm trying to upload my app's old Dropbox support to the newest SDK.  Has uploadURL been killed?  All I see is "upload" -- but there's no argument for the source file, so how do you use it?  Some examples for how to use this stuff would be nice.    DBRoulette is kind of useless for most purposes.

EDIT: Ok I managed to find an example buried in this byzantine documentation.  But it is out of date.  There are new arguments in the declaration here different from the example.  

http://dropbox.github.io/dropbox-sdk-obj-c/api-docs/latest/Classes/DBFILESUserAuthRoutes.html#/c:objc(cs)DBFILESUserAuthRoutes(im)uploadData:mode:autorename:clientModified:mute:propertyGroups:inputData:

And neither one is working for me.  Here is what I am doing -- it says "Instance method '-uploadData:mode:autorename:clientModfified:mute:propertyGroups:inputData:' not found"

Is there some way to see the actual function headers or declarations on my machine, since the documentation is so contradictory?  I choose "Go To Definition/Declaration" from XCode or or search files for "uploadData" and nothing comes up.

[[[[DBClientsManager authorizedClient].filesRoutes uploadData:finalPath
         mode: [[[DBFILESWriteMode alloc] initWithOverwrite] autorelease]
         autorename: @(NO)
         clientModfified:nil
         mute: @(NO)
         propertyGroups:nil
         inputData: fileData]
      setResponseBlock:^(DBFILESFileMetadata *result, DBFILESUploadError *routeError, DBRequestError *error) {
