There are three versions of the examples provided:

https://github.com/dropbox/dropbox-sdk-obj-c/tree/master/Examples/DBRoulette

There's one for each supported installation method, and they're pre-configured for their respective installation method, but they don't come with the SDK pre-installed. You'll need to follow the instructions for the respective installation method, just as you would with your own app:

Based on the path, it looks like you're trying the "subproject" method example. Did you finish the instructions for that?

Hey Greg,

 

I used the Carthage method for my own app.  This installed the dropbox SDK within my app folder -- and it includes the Example project(s).  

 

So  are you saying that in order to run the Example project I have to run "carthage update --platform iOS" again within the Example project's Carthage folder?  Which downloads *another* entire copy of the SDK including another Example project?  

 

If I do that, then the DBRoulette project already has the framework added, and the run script.  However, when I compile I get a lot of errors:

    Yes, that downloads the library and installs it into that project.

     

    It looks like you're running in to an issue with the sample app not being up to date with the latest version of the library though. We're looking into it, but you can use 2.0.5 for now. That is, use a Cartfile like:

     

    # ObjectiveDropboxOfficial
github "https://github.com/dropbox/dropbox-sdk-obj-c" ~> 2.0.5

      For reference, the sample app has been updated to work with the latest version of the SDK.
