Signing an oAuth request with HMAC-SHA1

Question

I'm struggling on iOS to sign an oAuth request with oAuth. I don't need to sign on behalf of a user, so I just have my app's key/secret from my provider. Is there an iOS library or 3rd party library which I can use to just generate the nonce, timestamp and sign the request?

Answer 1

Perhaps the Objective-C library oauthconsumer can be of help?

Found here: http://oauth.net/code/

Answer 2

I was having similar issues. I found libraries like the one linked above a little verbose for what I needed. I ended up creating my own signature following these steps from Twitter: https://dev.twitter.com/docs/auth/creating-signature. They provide really clear steps on how to create the signature.
