Currently I am attempting to perform a segue to a second view controller after a user logs in with Facebook using firebase
I was able to sort of get this to work. My problem is I have to actually log-in twice before the Segue is activated. Any suggestions?
see my CODE below
private var fbLoginSuccess = false //This is gobal
override func viewDidAppear(_ animated: Bool) {
if (FBSDKAccessToken.current() != nil && fbLoginSuccess == true)
{
performSegue(withIdentifier: "Home", sender: self)
}
}
#IBAction func facebookLogin(sender: UIButton) {
let facebookLogin = FBSDKLoginManager()
facebookLogin.logIn(withReadPermissions: ["public_profile", "email"], from: self, handler: {
(facebookResult, facebookError) -> Void in
if facebookError != nil {
print("Facebook login failed. Error \(String(describing: facebookError))")
} else if (facebookResult?.isCancelled)! {
print("Facebook login was cancelled.")
} else {
let credential = FacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current().tokenString)
Auth.auth().signIn(with: credential) { (user, error) in
if error != nil {
print("Login failed. \(String(describing: error))")
} else {
fbLoginSuccess = true
print("Logged in!")
if (facebookResult?.grantedPermissions.contains("email"))! {
}
}
}
}
})
}
It appears that you're only calling performSegue(withIdentifier:) in viewDidAppear. If you want the segue to occur after signing in, then you need to include it there.
let facebookLogin = FBSDKLoginManager()
facebookLogin.logIn(withReadPermissions: ["public_profile", "email"], from: self, handler: {
(facebookResult, facebookError) -> Void in
if facebookError != nil {
print("Facebook login failed. Error \(String(describing: facebookError))")
} else if (facebookResult?.isCancelled)! {
print("Facebook login was cancelled.")
} else {
let credential = FacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current().tokenString)
Auth.auth().signIn(with: credential) { (user, error) in
if error != nil {
print("Login failed. \(String(describing: error))")
} else {
fbLoginSuccess = true
print("Logged in!")
if (facebookResult?.grantedPermissions.contains("email"))! {
}
performSegue(withIdentifier: "Home", sender: self)
}
}
}
})

I am trying to add users to my Firebase cloud
I connected my project to the console.firebase
While I fill in the email and password it is not adding to my firebase.
I have the following code:
#IBAction func registerButton(_ sender: Any) {
signUp()
}
this is a button for register
and this is the func signup:
func signUp (){
let name = nameValue.text
let password = passwordValue.text
let email = emailValue.text
if (!password!.isEmpty && !email!.isEmpty) {
Auth.auth().createUser(withEmail: email ?? "", password: password ?? "") { (result, error) in
if error == nil {
if let result = result {
}
}
}
}
else {
showAlert()
}
}
Can anybody help to figure out this problem?
here is the solution to my problem:
if (!name!.isEmpty && !password!.isEmpty && !email!.isEmpty) {
Auth.auth().createUser(withEmail: email ?? "", password: password ?? "") { (authResult, error) in
if let e = error {
print(e.localizedDescription)
} else {
// self.performSegue(withIdentifier: "main", sender: self)
}
}
}
I would like to know how to perform a modal segue after the remote notification access has been granted from the dialog box. I have set up my remote notification in the app delegate.
func registerANSForApplication(_ application: UIApplication,withBlock block: #escaping (_ granted:Bool) -> (Void)){
InstanceID.instanceID().instanceID { (result, error) in
if let error = error {
print("Error fetching remote instange ID: \(error)")
} else if let result = result {
print("Remote instance ID token: \(result.token)")
AppDelegate.isToken = result.token
}
}
let current = UNUserNotificationCenter.current()
let options : UNAuthorizationOptions = [.sound, .badge, .alert]
current.requestAuthorization(options: options) { (granted, error) in
guard granted else{
return
}
if error != nil{
print(error?.localizedDescription ?? "")
}else{
Messaging.messaging().delegate = self
current.delegate = self
DispatchQueue.main.async {
application.registerForRemoteNotifications()
}
}
}
}
Then, in my view controller, I have this code:
let appDelegate = UIApplication.shared.delegate as!
appDelegate.registerANSForApplication(UIApplication.shared) { (granted) -> (Void) in
self.performSegue(withIdentifier: "MembershipVC", sender: nil)
}
The problem is whether the user allows or denies the access to notification, the segue is not executed.
Thank you for your help.
You have to call the block parameter
Replace
current.requestAuthorization(options: options) { (granted, error) in
guard granted else{
return
}
if error != nil{
print(error?.localizedDescription ?? "")
}else{
Messaging.messaging().delegate = self
current.delegate = self
DispatchQueue.main.async {
application.registerForRemoteNotifications()
}
}
}
with
current.requestAuthorization(options: options) { (granted, error) in
if error != nil {
print(error?.localizedDescription ?? "")
block(false)
} else {
Messaging.messaging().delegate = self
current.delegate = self
DispatchQueue.main.async {
application.registerForRemoteNotifications()
block(granted)
}
}
}
I currently have the correct code to customize the drop in UI straight from the iOS SDK docs. However it runs but is still the default AWS look. I have browsed profusely for the solution but to no avail.
import UIKit
import AWSAuthCore
import AWSAuthUI
import AWSMobileClient
class SignInViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
showSignIn()
//
AWSMobileClient.default().initialize { (userState, error) in
if let userState = userState {
switch(userState){
case .signedIn:
self.createAlert(title: "You are already signed in!", message: "Sign out first")
DispatchQueue.main.async {
// self.signInStateLabel.text = "Signed out"
}
case .signedOut:
AWSMobileClient.default().showSignIn(navigationController: self.navigationController!, { (userState, error) in
if(error == nil){ //Successful signin
DispatchQueue.main.async {
// self.signInStateLabel.text = "Logged In"
// self.signOutButton.isHidden = false
// self.tableView.reloadData()
}
}
})
default:
AWSMobileClient.default().signOut()
}
} else if let error = error {
print(error.localizedDescription)
}
}
// Do any additional setup after loading the view.
}
func showSignIn() {
if !AWSSignInManager.sharedInstance().isLoggedIn{
AWSAuthUIViewController.presentViewController(with: self.navigationController!, configuration: nil, completionHandler: {(provider: AWSSignInProvider, error: Error?) in
if error != nil {
print("Error occured: \(String(describing: error))")
}else{
//Sign in Successful
print("Logged in with provider \(provider.identityProviderName)with Token: \(provider.token())")
}
})
AWSMobileClient.default()
.showSignIn(navigationController: self.navigationController!,
signInUIOptions: SignInUIOptions(
canCancel: true,
logoImage: UIImage(named: "MyCustomLogo"),
backgroundColor: UIColor.red)) { (result, err) in
//handle results and errors
}
}
}
func createAlert (title: String, message: String){
let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertController.Style.actionSheet)
alert.addAction(UIAlertAction(title: "Ok", style: UIAlertAction.Style.default, handler: { (Action) in
alert.dismiss(animated: true, completion: nil)
}))
self.present(alert, animated: true, completion: nil)
}
}
I try to customize it in func showSignIn(). I would like to customize this UI to my own preferences.
Looks like you have the right idea with SignInUIOptions but might just need less code and in the right places. Here's what's worked for me:
In AppDelegate:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Initialize AWSMobileClient singleton
AWSMobileClient.default().initialize { (userState, error) in
if let userState = userState {
print("UserState: \(userState.rawValue)")
} else if let error = error {
print("error: \(error.localizedDescription)")
}
}
return true
}
In ViewController:
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
if !AWSMobileClient.default().isSignedIn {
showLoginScreen()
return
}
}
func showLoginScreen() {
AWSMobileClient.default().showSignIn(
navigationController: self.navigationController!,
signInUIOptions: SignInUIOptions(
canCancel: false,
logoImage: UIImage(named: "MyLogo"),
backgroundColor: UIColor.red,
secondaryBackgroundColor: UIColor.red,
disableSignUpButton: true)
) { (signInState, error) in
if let signInState = signInState {
print("Sign in flow completed: \(signInState)")
} else if let error = error {
print("error logging in: \(error.localizedDescription)")
}
}
}
When I log in with a facebook account in a view, I pass it a second view, in the second view I want a fetch query but in the view log I get permission denied and I dont see the info.
I have a normal firebase account, application test facebook.
this is the code view log in
#IBAction func InicioSesionFacebook(_ sender: Any)
{
esperaSesion.isHidden = false
esperaSesion.startAnimating()
let fbLoginManager = FBSDKLoginManager()
fbLoginManager.logIn(withReadPermissions: ["public_profile", "email"], from: self) { (result, error) in
if let error = error {
print("Failed to login: \(error.localizedDescription)")
self.esperaSesion.stopAnimating()
return
}
guard let accessToken = FBSDKAccessToken.current() else {
print("Failed to get access token")
self.esperaSesion.stopAnimating()
return
}
let credential = FacebookAuthProvider.credential(withAccessToken: accessToken.tokenString)
// Perform login by calling Firebase APIs
Auth.auth().signIn(with: credential, completion: { (user, error) in
if let error = error
{
self.esperaSesion.stopAnimating()
print("Login error: \(error.localizedDescription)")
let alertController = UIAlertController(title: "Login Error", message: error.localizedDescription, preferredStyle: .alert)
let okayAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(okayAction)
self.present(alertController, animated: true, completion: nil)
return
}
else
{
let fbloginresult : FBSDKLoginManagerLoginResult = result!
if (result?.isCancelled)!
{
return
}
else
{
// Present the main view
self.esperaSesion.stopAnimating()
if let viewController = self.storyboard?.instantiateViewController(withIdentifier: "NavigationMasterController")
{
UIApplication.shared.keyWindow?.rootViewController = viewController
self.dismiss(animated: true, completion: nil)
}
}
}
})
}
}
this is the code in the second view, a query
import FirebaseAuth
import FirebaseDatabase
import FBSDKLoginKit
var refDB: DatabaseReference!
override func viewDidLoad()
{
super.viewDidLoad()
refDB = Database.database().reference()
CerrarSesion.layer.cornerRadius = 8
imagenPerfil.layer.cornerRadius = imagenPerfil.frame.height/2
imagenPerfil.clipsToBounds = true
verDatos()
// Do any additional setup after loading the view.
}
func verDatos()
{
let userID = Auth.auth().currentUser?.uid
refDB.child("users").child(userID!).observeSingleEvent(of: .value, with: { (snapshot) in
// Get user value
let value = snapshot.value as? NSDictionary
let nombre = value?["nombre"] as? String ?? ""
let apellido = value?["apellido"] as? String ?? ""
self.nombreUsuario.text = nombre
self.apellidoUsuario.text = apellido
// ...
}) { (error) in
print(error.localizedDescription)
}
}
and the button log out
#IBAction func CerrarSesion(_ sender: Any)
{
do
{
try Auth.auth().signOut()
self.view.window?.rootViewController?.dismiss(animated: true, completion: borrarUserDefaults)
}
catch let error as NSError
{
print (error.localizedDescription)
}
}
how is the correct form for log out when I logged in with facebook account?
You can check out my YouTube Tutorial on this exact topic !
https://www.youtube.com/watch?v=BfwNf-W-R4U
The version of the Facebook API that you are using is dated. The Login function should look something like this
let loginManager = LoginManager()
loginManager.logIn(readPermissions: [.publicProfile], viewController: self) {loginResult in
switch loginResult {
case .failed(let error):
print("error: \(error)")
case .cancelled:
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
print(grantedPermissions)
print(declinedPermissions)
fbAccessToken = accessToken
let credential = FacebookAuthProvider.credential(withAccessToken: (fbAccessToken?.authenticationToken)!)
Auth.auth().signIn(with: credential) { (user, error) in
if let error = error {
print(error)
return
}
currentUser = Auth.auth().currentUser
moveToHomeScreen()
print("Logged in!")
}
}
}
I think that you are getting a permissions error because the parameter name from the AccessToken changed and you are passing the wrong value. (Sorry I cant recall what the change was).
If you are following the Facebook API instructions on the facebook developer portal they are horrendously out of date iOS 9 I think.
I am able to successfully authenticate login with facebook using basic SDK procedures, but am having some confusion when I am trying to authenticate with Firebase. I have read through the documentation and copied and pasted the code but I am still getting a warning that reads
'logInWithReadPermissions(_:handler:)' is deprecated: use logInWithReadPermissions:fromViewController:handler: instead facebookLogin.logInWithReadPermissions(["email"], handler: instead.
1) What does this warning mean and how do I fix it?
2) With emails and password sign in you see the registered users created, but how do I know and see if users were registered with facebook authentication in the Firebase DB?
Thanks for any help or direction!
import UIKit
import Firebase
import FBSDKCoreKit
import FBSDKLoginKit
class ViewController: UIViewController, FBSDKLoginButtonDelegate {
let loginButton: FBSDKLoginButton = {
let button = FBSDKLoginButton()
button.readPermissions = ["email"]
return button
}()
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(loginButton)
loginButton.center = view.center
loginButton.delegate = self
let ref = Firebase(url: "https://my-app.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 loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!) {
if error == nil {
print("completed login")
self.performSegueWithIdentifier("showNew", sender: self)
}
else {
print(error.localizedDescription)
}
}
func loginButtonDidLogOut(loginButton: FBSDKLoginButton!) {
print("user logged out")
}
func loginButtonWillLogin(loginButton: FBSDKLoginButton!) -> Bool {
return true
}
}
Try something like (compiles without warnings to me):
let currentToken = FBSDKAccessToken.currentAccessToken()
// Show login only if we had not logged in before
if (currentToken == nil || !currentToken.hasGranted("email")) {
let ref = Firebase(url: "https://my-app.firebaseio.com")
let facebookLogin = FBSDKLoginManager()
facebookLogin.logInWithReadPermissions(["email"], fromViewController: self, handler: {
(facebookResult, facebookError) -> Void in
if facebookError != nil {
log.error("Facebook login failed. Error \(facebookError)")
.
