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.
