DIAuth is authorization system for two step authorization: social network auth + own server auth (optional). It’s usefull for login into your app via social app account (OAuth). It wraps social network authorization, serves as a facade for different auth-services and provide one authorization interface and a solid workflow for whole authorization process. DIAuth manage caching social network account via native instruments of social network SDK’s or via store account data into keychain.

There are just couple social networks inside:

  • Facebook
  • VKontakte

You can easily make your own class for authorising inside the system (see usage)


Authorization Status

All the authorization process is displayed by auth-status


You can process the status changing by observing it in NSNotificationCenter

NSNotificationCenter.defaultCenter().addObserver(self, selector: "authStatusDidChange:", name: kDIAuthStatusDidChangeNotification, object: nil)

@objc func authStatusDidChange(notification: NSNotification) {
        if let rawStatus = notification.userInfo?[kDIAuthStatusDidChangeNewStatusKey] as? String {
            if let status = DIAuthStatus(rawValue: rawStatus) {


Use this DIAuth singleton method for starting auth process

func start(socialNetwork: DISocialNetwork?, newConnector:DIAuthConnector)

First parameter is social network instance (child of DISocialNetwork class) or nil. Second one is your DIAuthConnector implementer that will be used for taking settings during auth process and for callback when social authorization is finished.

Start DIAuth when your app has launched

func appLaunchedWithOptions(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) {
    DIAuth.sharedInstance.start(nil, newConnector: connector)

If you pass nil as the first parameter, DIAuth will check cached social network authorization first. If there isn’t anything in the cache, auth-status will change to WaitingForUser.

When user has started authorization with specific social network type (fb, vk or other), you should call start method with social network instance (you just need to init it, all the customization will be done inside DIAuth with a help of your DIAuthConnector implementer)

func fbLoginButtonPressed() {
    DIAuth.sharedInstance.start(DIFacebook(), newConnector: connector)

Call logOut method when user logs out from your app account. DIAuth will log out from social network and clean cache data.


Otherwise next time launching your app DIAuth will use cached social network account.

AppDelegate methods

Call DIAuth from your appDelegate to pass it some app events

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) {
    DIAuth.sharedInstance.application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) {
    DIAuth.sharedInstance.application(application, didFinishLaunchingWithOptions: launchOptions)

func applicationDidBecomeActive(application: UIApplication) {

Custom Social Networks

If you want additional authorization option (different social network, your own e-mail authorization,…) just add an appropriare DISocialNetwork child class, implement some necessary methods in it and pass it into DIAuth start (like DIFacebook, DIVKontakte)

class YourCustomSocialNetwork: DISocialNetwork {

    //MARK: Events from appDelegate
    override func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
        //override if necessary

    override func applicationDidBecomeActive(application: UIApplication) {
        //override if necessary

    override func resetAuthData() {
        //reset account data
        //override if necessary

    override class func snTypeString() -> String {
        //kind of login type id for DIAuth system
        return "yourLoginType"

    override func snCachedAuthDataIsAvailable() -> Bool {
        //return true or false depending on having cache account data

    override func openSession(appID: String, forcedWebView: Bool, vc: UIViewController? = nil) {
        newSocialNetworkService.logInWithPermissions(permissions(), inApp: forcedWebView, fromViewController: nil) { (result, error) -> Void in
            if error != nil {
                //social network auth failed
            } else {
                //social network auth succeded
                self.setAuthData(result.userID, newToken: result.tokenString, newUserName: result.userName)

And of course don’t forget about your new social network in your DIAuthConnector implementer


  • iOS 7.0+, Xcode 7.0+



You can integrate DIAuth into your project manually as a submodule. Core files are here

DIAuth uses SocialNetwork SDKs and KeyChain wrapper, so you need to add them in your code (manualy or addin them into your podfile)

pod 'KeychainAccess'
pod 'VK-ios-sdk'
pod 'FBSDKCoreKit'
pod 'FBSDKLoginKit'


Now we have some issues connected with interactions between DIAuth as a pod, FBSDK and Bolts.framework (DIAuth dependensies). It looks like the SO issue but all of those solutions didn’t help with DIAuth pod.

~~DIAuth is available through CocoaPods. To install
it, simply add the following line to your Podfile:~~

pod "DIAuth"
