Firebase UI Auth Provider iOS Swift示例-Java 学习之路

我正在开始一个新的iOS Swift应用程序，并希望使用FirebaseUI Auth . 这是在 Drop-in authentication solution Firebase Auth下讨论它的文档的链接 . 适用于Android的FirebaseUI Auth非常简单易用 . 似乎iOS示例已过时，因为API似乎在版本之间发生了巨大变化 . 看起来它们的版本是3.1 .

方向也有点裸：https://github.com/firebase/FirebaseUI-iOS

有人可以帮助我，并为Facebook和谷歌登录提供一个示例AppDelegate和ViewController？

我正在使用Xcode 8.3，Swift 3 .

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

这是我的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.
}

}

这是我的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

    }
}
}

你的代码似乎没问题！要与Google / Facebook / Twitter Auth通信，您必须为您的应用添加对URL Scheme的支持 . 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)
}

你非常接近！ Wei Jay是正确的，您需要在应用Info.plist文件中定义您的URL方案，并在您的应用委托中添加回调 .

基本上你需要将下面的内容添加到plist的根目录中 .

<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>

您可以从GoogleService-Info.plist文件中的 RESERVED_CLIENT_ID 条目中获取您的Google应用ID .

接下来，我的AppDelegate文件只实现了openURL委托方法：

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
}
