Firebase UI Auth Provider iOS Swift示例
我正在开始一个新的iOS Swift应用程序，并希望使用FirebaseUI Auth。 以下是在Drop-in authentication solution Firebase Auth下与其进行讨论的文档的链接。 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。 它看起来像3.1版本。
方向也有点露点： 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方案的支持。 看一下这个！
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。
CFBundleURLTypes CFBundleURLSchemes com.googleusercontent.apps.{app-id-here} CFBundleURLSchemes fb{app-id-here} FacebookAppID {app-id-here} FacebookDisplayName {name-here} LSApplicationQueriesSchemes fbauth2
您可以从GoogleService-Info.plist文件中的RESERVED_CLIENT_ID条目中获取您的Google应用内容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 }
这里解释如何设置Facebook的设置
