OAuth2 in Objective-C

Goals

OAuth2 implements only a fraction of RFC 6749. It’s designed to handle Resource Owner Password Credentials Grant only.

Quick setup

Build Universal target, you’ll find a copy of OAuth2.framework in the project directory.
Copy OAuth2.framework to your project. Make sure to add it to Embedded Binaries section of the project.

Example

SFTToken *aToken;

[SFTOAuth requestAccessToken:@"username"
                    password:@"password"
                    clientId:@"client_id"
                clientSecret:@"client_secret"
        authenticationServer:[NSURL URLWithString:@"http://auth.server.test"]
                            :^(SFTToken *token, NSError *error)
         {
             aToken = token; 
         }];

// aRequest is some request

[SFTOAuth performRequest:aRequest
               withToken:aToken
                clientId:@"client_id"
            clientSecret:@"client_secret"
    authenticationServer:[NSURL URLWithString:@"http://auth.server.test"]
                        :^(NSData *data, NSError *error)
     {
         // ... do your thing
     }];

Patterns

Store SFTToken object between sessions, SFTOAuth will update it as necessary with refresh tokens and expiration dates.
