I am trying to do Sign In with Facebook/Firebase Swift authentication, and I'm at the point where there's a functioning button. I am trying to run something that performs a segue once the login is complete, but I have not been successful in my tries.
func viewDidLoad(){
let loginButton = LoginButton(readPermissions: [ .publicProfile, .email])
loginButton.center = view.center
view.addSubview(loginButton)
if let accessToken = AccessToken.current {
print("signed in")
}
}
func loginButtonDidLogOut(_ loginButton: LoginButton){
print("logged out of fb")
}
func loginButton(_ loginButton: LoginButton!, didCompleteWith result: LoginResult!, error: Error!) {
if error != nil {
print(error)
return
}

Hellos developers,
who anyone can help me with one issue , I try to make a Facebook login and after that I want to go to another view.
But I can't make that happens, could some one can help me with that?
I put my code below:
import UIKit
import FBSDKLoginKit
import FBSDKCoreKit
class ViewController: UIViewController , LoginButtonDelegate{
func loginButton(_ loginButton: FBLoginButton, didCompleteWith result: LoginManagerLoginResult?,
error: Error?) {
loginButton.permissions = ["public_profile","email"]
if error != nil {
print("Something is Wrong... \(String(describing: error))")
return
}
print("Succesful loged in !")
}
func loginButtonDidLogOut(_ loginButton: FBLoginButton) {
loginButton.titleLabel?.text = "Adios"
print("GoodBye ")
}
override func viewDidLoad() {
super.viewDidLoad()
let loginButton = FBLoginButton()
loginButton.center = view.center
view.addSubview(loginButton)
loginButton.permissions = ["public_profile", "email"]
loginButton.addTarget(self, action: #selector(getUserFBInfo), for: .touchUpOutside)
}
#objc func getUserFBInfo(){
print("se logro ")
let token = AccessToken.current
if token == AccessToken.current {
performSegue(withIdentifier: "secondActivity", sender: self)
}else if token!.isExpired{
print("no sucede nada")
}
}
}
If you want the LoginButtonDelegate to call your delegate function (e.g. loginbutton:didCompleteWithResult:error:), remember to assign the delegate to the FBLoginButton.
In the above code, since the delegate is the UIViewController itself (not a must), you will need to add loginButton.delegate = self
I ran the facebook auth and it works well, but When i go to the firebase authentication tab, the user is not there
Here's the code
import UIKit
import FBSDKCoreKit
import FBSDKLoginKit
import FirebaseFacebookAuthUI
class ViewController: UIViewController {
#IBOutlet weak var name: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let loginButton = FBSDKLoginButton()
loginButton.readPermissions = ["public_profile", "email"]
// Optional: Place the button in the center of your view.
loginButton.center = view.center
view.addSubview(loginButton)
}
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
if let error = error {
print(error.localizedDescription)
return
} else {
let credential = FacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current().tokenString)
print(credential)
Auth.auth().signIn(with: credential) { (user, error) in
if let _ = error {
return
}
self.name.text = "\(user)"
print("user is sign in")
}
}
}
}
Do i need to do any extra configuration?
Before moving to Swift 3 the user had to log in to the app by Facebook, and then it automatically logged in to your Firebase account. Everything was good, but then I moved to Swift 3. The log in button still exists, but after it asks for permission to log in to Facebook - nothing happens.
Here is my code before moving to Swift 3:
var loginButton: FBSDKLoginButton = FBSDKLoginButton()
override func viewDidLoad() {
super.viewDidLoad()
loginButton.hidden = true
FIRAuth.auth()?.addAuthStateDidChangeListener { auth, user in
if let user = user {
// User is signed in.
currentEmail = user.email!
print("DONE")
NSNotificationCenter.defaultCenter().postNotificationName("dontShowLogInView", object: nil)
} else {
// No user is signed in.
self.loginButton.center = self.view.center
self.loginButton.readPermissions = ["public_profile", "email", "user_friends"]
self.loginButton.delegate = self
self.view.addSubview(self.loginButton)
self.loginButton.hidden = false
}
}
// Optional: Place the button in the center of your view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!) {
print("user logged in")
self.loginButton.hidden = true
activityIndicator.startAnimating()
if error != nil {
self.loginButton.hidden = false
activityIndicator.stopAnimating()
print("???")
//handle errors
} else if result.isCancelled {
self.loginButton.hidden = false
activityIndicator.stopAnimating()
let loginManager = FBSDKLoginManager()
loginManager.logOut()
//handle cancel
print("canceled")
} else {
let credential = FIRFacebookAuthProvider.credentialWithAccessToken(FBSDKAccessToken.currentAccessToken().tokenString)
FIRAuth.auth()?.signInWithCredential(credential) { (user, error) in
print("user logged to firebase app")
}
}
}
func loginButtonDidLogOut(loginButton: FBSDKLoginButton!) {
print("user logged out")
}
And this is the code after moving to Swift 3:
var loginButton: FBSDKLoginButton = FBSDKLoginButton()
override func viewDidLoad() {
super.viewDidLoad()
//getFBUserData()
loginButton.isHidden = true
FIRAuth.auth()?.addStateDidChangeListener { auth, user in
if let user = user {
// User is signed in.
currentEmail = user.email!
print("DONE")
print(currentEmail)
NotificationCenter.default.post(name: Notification.Name(rawValue: "dontShowLogInView"), object: nil)
} else {
// No user is signed in.
self.loginButton.center = self.view.center
self.loginButton.readPermissions = ["public_profile", "email", "user_friends"]
self.loginButton.delegate = self
self.view.addSubview(self.loginButton)
self.loginButton.isHidden = false
}
}
// Optional: Place the button in the center of your view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func loginButton(loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: NSError!) {
print("user logged in")
self.loginButton.isHidden = true
activityIndicator.startAnimating()
if error != nil {
self.loginButton.isHidden = false
activityIndicator.stopAnimating()
print("???")
//handle errors
} else if result.isCancelled {
self.loginButton.isHidden = false
activityIndicator.stopAnimating()
let loginManager = FBSDKLoginManager()
loginManager.logOut()
//handle cancel
print("canceled")
} else {
let credential = FIRFacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current().tokenString)
FIRAuth.auth()?.signIn(with: credential) { (user, error) in
print("user logged to firebase app")
}
}
}
func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!) {
print("user logged out")
}
I am trying to perform a FacebookLogin using Firebase and the Facebook Login button, but I keep getting this

My ViewController code is as follows:
import UIKit
import Firebase
import FBSDKCoreKit
import FBSDKLoginKit
class ViewController: UIViewController, FBSDKLoginButtonDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
var loginButton = FBSDKLoginButton()
loginButton.readPermissions = ["public_profile", "email", "user_friends"]
loginButton.center = self.view.center
loginButton.delegate = self
self.view.addSubview(loginButton)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Facebook Login
func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!)
{
let ref = Firebase(url: "https://biblos-thebookapp.firebaseio.com")
let facebookLogin = FBSDKLoginManager()
facebookLogin.logInWithReadPermissions(["email"], handler: {
(facebookResult, facebookError) -> Void in
if facebookError != nil {
print("Facebook login failed. Error \(facebookError)")
} else if facebookResult.isCancelled {
print("Facebook login was cancelled.")
} else {
let accessToken = FBSDKAccessToken.currentAccessToken().tokenString
ref.authWithOAuthProvider("facebook", token: accessToken,
withCompletionBlock: { error, authData in
if error != nil {
print("Login failed. \(error)")
} else {
print("Logged in! \(authData)")
}
})
}
})
}
func loginButtonDidLogOut(loginButton: FBSDKLoginButton!)
{
print("User logged out...")
}
}
This method is deprecated. Try to use logInWithReadPermissions:fromViewController:handler: instead and pass your UIViewController or nil (topmost will be used).
https://developers.facebook.com/docs/reference/ios/current/class/FBSDKLoginManager/
here's the code
override func viewDidLoad()
{
if (FBSDKAccessToken.currentAccessToken() == nil)
{
print("Not logged in..")
}
else
{
let loginView : FBSDKLoginButton = FBSDKLoginButton()
self.view.addSubview(loginView)
loginView.center = self.view.center
loginView.readPermissions = ["public_profile", "email", "user_friends"]
loginView.delegate = self //shows error:view controller does not conform to protocol 'FBSDKLoginButtonDelegate'
}
super.viewDidLoad()
}
And the loginButton method
func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!)
{
if error == nil
{
print("Login complete.")
self.performSegueWithIdentifier("showNew", sender: self)
}
else
{
print(error.localizedDescription)
}
}
func loginButtonDidLogOut(loginButton: FBSDKLoginButton!)
{
print("User logged out...")
}
The view controller is frontpageViewConroller,I have logged into facebook registered with the AppId downloaded the iOS SDK and imported them,unable to solve this help me out
