AFNetworking Extension for OAuth 1.0a Authentication

branch: master



Register your application to launch from a custom URL scheme, and use that with the path /success as your callback URL. The callback for the custom URL scheme should send a notification, which will complete the OAuth transaction.

Here's how to create a client and authenticate:

AFOAuth1Client *twitterClient = [[[AFOAuth1Client alloc] initWithBaseURL:[NSURL URLWithString:@""] key:@"..." secret:@"..."] autorelease];

// Your application will be sent to the background until the user authenticates, and then the app will be brought back using the callback URL
[twitterClient authorizeUsingOAuthWithRequestTokenPath:@"/request_token" userAuthorizationPath:@"/authorize" callbackURL:[NSURL URLWithString:@"x-com-YOUR-APP-SCHEME://success"] accessTokenPath:@"/access_token" success:^(AFOAuth1Token *accessToken) {
    NSLog(@"Success: %@", accessToken);
} failure:^(NSError *error) {
    NSLog(@"Error: %@", error);

Here's how to respond to the custom URL scheme on iOS:

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
    NSNotification *notification = [NSNotification notificationWithName:kAFApplicationLaunchedWithURLNotification object:nil userInfo:@{kAFApplicationLaunchOptionsURLKey: url}];
    [[NSNotificationCenter defaultCenter] postNotification:notification];

    return YES;
