iOS framework for handling authentication with Facebook and Twitter with reverse-auth support.

Thanks to native support for Facebook and Twitter accounts in iOS, it's much easier to implement one-tap login and registration to your apps now. However there are a few pain points in this process:

• iOS5 doesn't have native Facebook authentication support
• Twitter support between iOS5 and iOS6 is slightly different and confusing
• iOS-supported Twitter login uses a "global" Twitter app rather than your own, so tokens cannot be used anywhere else
• A custom "reverse-auth" process needs to be implemented to obtain Twitter tokens that can be stored on server side
• Facebook no longer supports "offline access" permission, so your app needs to reauthenticate at every launch, renewing its access token

HPSocialNetworkManager aims to ease the integration process by adding native support for all of these scenarios, and giving you a single interface that you can use to authenticate a user with one or more social networks.

Basic usage is like this:

[[HPAccountManager sharedManager] setupWithFacebookAppID:@"Facebook App ID"
                                  facebookAppPermissions:@[@"email", @"user_location", @"user_about_me"]
                                      twitterConsumerKey:@"Twitter Consumer Key"
                                   twitterConsumerSecret:@"Twitter Consumer Secret"];

[[HPAccountManager sharedManager] authenticateAccountOfType:HPAccountTypeTwitter
                                               withHandler:^(HPAccount *authenticatedAccount, NSDictionary *profileInfo, NSError *error) {
                                                   if (error) {
                                                       NSLog(@"Failed to authenticate: %@", error);
                                                   } else {
                                                       NSLog(@"Authenticated: %@", authenticatedAccount.identifier);
                                                   }
                                               }];

And that's it! Completion block is called with an HPAccount instance that contains the identifier and account type, and a profileInfo dictionary that contains the raw profile data received from Twitter or Facebook.

You can see an example of this by checking out the example project in this repo.

Copy and include the HPAccountManager directory (found here under Dependencies) in your own project. There are some other dependencies as well, you can see their details below under Requirements.

If your project uses ARC, you will have to mark the following files to be compiled without ARC, using the -fno-objc-arc flag in build settings:

• HPAccountManager.m
• HPAccount.m
• NSData+Base64.m
• OAuth+Additions.m
• OAuthCore.m

On the other hand, if your project does not use ARC, you will have to mark the following files to be compiled with ARC, using the -fobj-arc flag:

• TWAPIManager.m
• TWSignedRequest.m

Project comes bundled with the following dependencies:

• ABOAuthCore
• TWAPIManager

And it depends on the Facebook SDK to work properly. You can download it and include it in your project from https://developers.facebook.com/ios/

Required system frameworks are:

• libsqlite3.dylib
• AdSupport.framework
• Accounts.framework
• Twitter.framework
• Social.framework
