Verify Twitter login from iPhone on the server side

Question

Ok, so I've currently implemented Facebook login in my app the following way:

I use the official FB framework to login the user. When I login, I get a authentication token, which is sent to my server. I then do another verification of the user (e.g. get "me" from Facebook, using the auth-token), and then return 32 char random key, which is used to identify the user in subsequent API-calls (to my server). An example.

I'm trying to figure out how to do the same with twitter, but I can't understand how to get the oath token in iOS? I have the server-side part working in another app, but no token to verify...

Please advice – is this (the FB way) how I should be doing this, or how would you go about the verification process?

Answer 1

Sean Cook, engineer @ Twitter has a github repo with a simple app that do exactly what you are trying to do, I'using this code in my app and it works like a charm.

Answer 2

There's a good article at dev.twitter.com describing exactly that. Basically you'll have to first get a special request token by setting the x_auth_mode parameter to the value reverse_aut and then get the proper access token by sending what you got in the first step as x_reverse_auth_parameters.
