Je démarre une nouvelle application iOS Swift et je veux utiliser FirebaseUI Auth. Voici le lien vers les docs où il en parle sous Drop-in authentication solutionFirebase Auth. Le FirebaseUI Auth pour Android était très simple et facile. Il semble que les exemples iOS sont périmés car l'API semble avoir changé radicalement d'une version à l'autre. On dirait qu'ils sont sur la version 3.1.Firebase UI Auth Provider iOS Swift Exemple

Les directions sont aussi un peu nu: https://github.com/firebase/FirebaseUI-iOS

Quelqu'un peut-il s'il vous plaît me aider et donner un exemple AppDelegate et ViewController pour facebook et google se connecter?

J'utilise Xcode 8.3, 3. Swift

PODFILE:

# Uncomment the next line to define a global platform for your project 
platform :ios, '9.0' 

target 'Project' do 
    # Comment the next line if you're not using Swift and don't want to use dynamic frameworks 
    use_frameworks! 

    pod 'FirebaseUI', '~> 3.1' 
    pod 'Firebase/Core' 
    pod 'Firebase/Database' 
    pod 'Firebase/Crash' 
    pod 'Firebase/Auth' 
    pod 'Firebase/Storage' 
    pod 'GoogleSignIn' 
    pod 'FBSDKLoginKit' 


    target 'ProjectTests' do 
    inherit! :search_paths 
    # Pods for testing 
    end 

    target 'ProjectUITests' do 
    inherit! :search_paths 
    # Pods for testing 
    end 

end 

Voici mon AppDelegate

import UIKit 
import CoreData 
import Firebase 
import FirebaseAuthUI 
import FirebaseAuth 
import GoogleSignIn 
import FBSDKLoginKit 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

    var window: UIWindow? 

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
    // Override point for customization after application launch. 
    FIRApp.configure() 
    return true 
} 

func applicationWillResignActive(_ application: UIApplication) { 
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. 
    // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game. 
} 

func applicationDidEnterBackground(_ application: UIApplication) { 
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits. 
} 

func applicationWillEnterForeground(_ application: UIApplication) { 
    // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background. 
} 

func applicationDidBecomeActive(_ application: UIApplication) { 
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface. 
} 

} 

Voici mon ViewController

import UIKit 
import Firebase 
import FirebaseAuth 
import FirebaseAuthUI 
import FirebaseDatabaseUI 
import FirebaseGoogleAuthUI 
import FirebaseFacebookAuthUI 
import FBSDKCoreKit 
import FBSDKLoginKit 

class ViewController: UIViewController, FUIAuthDelegate { 

    var kFacebookAppID = "111111111111111" 
override func viewDidLoad() { 
    super.viewDidLoad() 

    //FIRApp.configure() 
    checkLoggedIn() 
} 

func checkLoggedIn() { 
    FIRAuth.auth()?.addStateDidChangeListener { auth, user in 
     if user != nil { 
      // User is signed in. 
     } else { 
      // No user is signed in. 
      self.login() 
     } 
    } 
} 

func login() { 
    let authUI = FUIAuth.defaultAuthUI() 
    let facebookProvider = FUIGoogleAuth() 
    let googleProvider = FUIFacebookAuth() 
    authUI?.delegate = self 
    authUI?.providers = [googleProvider, facebookProvider] 
    let authViewController = authUI?.authViewController() 
    self.present(authViewController!, animated: true, completion: nil) 
} 

@IBAction func logoutUser(_ sender: AnyObject) { 
    try! FIRAuth.auth()!.signOut() 
} 

func authUI(_ authUI: FUIAuth, didSignInWith user: FIRUser?, error: Error?) { 
    if error != nil { 
     //Problem signing in 
     login() 
    }else { 
     //User is in! Here is where we code after signing in 

    } 
} 
}

Votre code semble fi ne! Pour communiquer avec Google/Facebook/Twitter Auth, vous devez ajouter un support pour un URL Scheme à votre application. CHECK THIS OUT!

func configureAuth() { 
    // TODO: configure firebase authentication 
    let provider: [FUIAuthProvider] = [FUIGoogleAuth(), FUIFaceBookAuth()] 
    FUIAuth.defaultAuthUI()?.providers = provider 

    // listen for changes in the authorization state 
    _authHandle = FIRAuth.auth()?.addStateDidChangeListener { (auth: FIRAuth, user: FIRUser?) in 

     // check if there is a current user 
     if let activeUser = user { 
      // check if current app user is the current FIRUser 
      if self.user != activeUser { 
       // sign in 
      } 
     } else { 
      // user must sign in 
      self.loginSession() 
     } 
    } 


} 

func loginSession() { 
    let authViewController = FUIAuth.defaultAuthUI()!.authViewController() 
    self.present(authViewController, animated: true, completion: nil) 
}

Vous êtes très proche! Wei Jay avait raison de dire que vous devez définir vos schémas d'URL dans le fichier Info.plist de votre application, et ajouter le rappel dans votre délégué d'application. Essentiellement, vous devez ajouter ce qui suit à la racine du plist.

<key>CFBundleURLTypes</key> 
<array> 
    <dict> 
     <key>CFBundleURLSchemes</key> 
     <array> 
      <string>com.googleusercontent.apps.{app-id-here}</string> 
     </array> 
    </dict> 
    <dict> 
     <key>CFBundleURLSchemes</key> 
     <array> 
      <string>fb{app-id-here}</string> 
     </array> 
    </dict> 
</array> 
<key>FacebookAppID</key> 
<string>{app-id-here}</string> 
<key>FacebookDisplayName</key> 
<string>{name-here}</string> 
<key>LSApplicationQueriesSchemes</key> 
<array> 
    <string>fbauth2</string> 
</array> 

Vous pouvez obtenir votre code d'application google de l'entrée RESERVED_CLIENT_ID dans votre fichier GoogleService-Info.plist.

Ensuite, mon fichier AppDelegate implémente que la méthode déléguée OpenUrl:

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { 

    let googleSignIn = GIDSignIn.sharedInstance().handle(url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String, annotation: options[UIApplicationOpenURLOptionsKey.annotation]) 

    let facebookSignIn = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String, annotation: options[UIApplicationOpenURLOptionsKey.annotation]) 

    return googleSignIn || facebookSignIn 
}
