In Facebook-Login when user enters "Username & Password" then on safari Facebook-SDK showing below screen.
If the user clicks on Not Now rather that on Continue as User. Facebook-SDK returns always Success
Is this Facebook-SDK bug or I am missing something.
I am adding below code:
func fbLoginWithViewController(viewController :UIViewController, completion : #escaping (_ loginResult: AnyObject, _ error: NSError?) -> Void) {
let loginManager = LoginManager()
loginManager.loginBehavior = .systemAccount
loginManager.logIn([ .publicProfile,.userFriends,.email ], viewController: viewController) { loginResult in
switch loginResult {
case .failed(let error):
print(error)
// show error method
self.isCancelled = false
completion(loginResult as AnyObject,error as NSError?)
case .cancelled:
print("User cancelled login.")
// show cancelled error
self.isCancelled = true
completion(loginResult as AnyObject,nil)
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
print("Logged in!")
//add api
self.isCancelled = false
if((FBSDKAccessToken.current()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email, picture.width(180).height(180)"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil){
self.fbAccesstoken = FBSDKAccessToken.current().tokenString
completion(result as AnyObject,nil)
}
})
}
}
}
}
Let me know if I am doing wrong!

I'm trying to implement facebook login on IOS using the new Facebook SDK. I'm getting stuck because I'm using my own custom facebook login button, where the SDK requires you to use its own login button. Can someone please help? I need to implement the part where someone click on the custom login button and authenticates using facebook after granting permission. Thanks!
I looked at the Documentation and it only provides support for Objective C and not swift
Here's what I had before the SDK update that no longer works
let loginManager = LoginManager()
loginManager.logIn(permissions: [ ".publicProfile, .email" ], viewController: self) { loginResult in
switch loginResult {
case .failed:
self.showMessage("Error logging you in.", "Could not log you in. Please try again.", .error)
case .cancelled:
self.showMessage("User canceled login.", "User cancelled login. Please try again.", .error)
case .success:
self.setFBUserData()
}
}
You can do this tricks. Initially create a facebookLoginButton but this will be hidden.
let facebookLoginButton = FBLoginButton(frame: .zero, permissions: [.publicProfile, .email])
facebookLoginButton.delegate = self
facebookLoginButton.isHidden = true
and in your custom button action you just needed to process the action
#IBAction func registerWithFacebook(_ sender: UIButton) {
facebookLoginButton.sendActions(for: .touchUpInside)
}
Hope you can understand.

For the Custom Design I did this way. First create a customView For the Custom Button and add Tap Gesture to that View.
create outlet of your view
#IBOutlet weak var fbLoginContainerView: UIView!
then add tap gesture to that view
let fbContainerTapGesture = UITapGestureRecognizer(target: self, action: #selector(fbLoginVIewAction(_:)))
fbLoginContainerView.addGestureRecognizer(fbContainerTapGesture)
in action getFBUserData
#objc func fbLoginVIewAction(_ sender: UITapGestureRecognizer) {
let loginManager = LoginManager()
loginManager.logIn(permissions: ["public_profile", "email"] , viewController: self) { loginResult in
switch loginResult {
case .failed(let error):
print(error)
case .cancelled:
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
self.getFBUserData()
}
}
}
fileprivate func getFBUserData(){
if((AccessToken.current) != nil){
GraphRequest(graphPath: "me", parameters: ["fields": "id, name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil){
self.dict = result as? [String : AnyObject]
print(result!)
print(self.dict)
self.showProgress(on: self.view)
guard let Username = self.dict["name"]! as? String else { return }
guard let UserId = self.dict["id"]! as? String else { return }
guard let Useremail = self.dict["email"]! as? String else { return }
let params = ["provider_user_id": UserId , "name": Username, "email": Useremail ,"provider": "FacebookProvider"] as! [String: AnyObject]
//Do your sign in network call here with parameter
}
}

I want to add login with Facebook account to my IOS app. I tried installing FacebookCore pod and FacebookLogin pod. My login action was successful but when I try to logout then login again, browser used the previous logged in account. Here is my code for login and logout action:
override func viewDidLoad() {
super.viewDidLoad()
let loginButton = LoginButton(readPermissions: [ .publicProfile ])
loginButton.center = view.center
//adding it to view
view.addSubview(loginButton)
loginButton.delegate = self
}
func loginButtonDidCompleteLogin(_ loginButton: LoginButton, result: LoginResult) {
print("logged in")
self.loginButtonClicked()
}
func loginButtonDidLogOut(_ loginButton: LoginButton) {
print("logged out")
AccessToken.current = nil
UserProfile.current = nil
FBSDKLoginManager().logOut()
}
//when login button clicked
func loginButtonClicked() {
let loginManager = LoginManager()
loginManager.loginBehavior = .web
loginManager.logIn(readPermissions: [.publicProfile], viewController: self, completion: {loginResult in
switch loginResult {
case .failed(let error):
print("loginnnnnn errrooorrr",error)
case .cancelled:
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
self.getFBUserData()
}
})
}
//function is fetching the user data
func getFBUserData(){
if((FBSDKAccessToken.current()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil){
self.dict = result as! [String : AnyObject]
self.isLogin = true
print(result!)
print(self.dict)
}
})
}
}
How to login with another account?
I had similar issue, I was receiving
you previously logged in to [app name] with Facebook. Would you like
to continue?
every time I wanted to log in into my app even after logout.
I solved it by using of Facebook native app (ver. 177).
You can 'log out' from your app here:
Menu Tab -> Settings -> 'Apps and Websites' -> 'Logged in with Facebook' -> Active -> select app -> tap Remove
I am stuck after coding the Facebook login.....!
After the login procedure I just end up with a logout button.
I would like to make use of the App Invites for iOS but I cant figure out how to integrate it...
The documentations on "Facebook.developer" is hard to understand.
This is my code so far in the view controller:
import UIKit
import FacebookLogin
import FBSDKLoginKit
class ViewController: UIViewController, FBSDKLoginButtonDelegate {
var dict : [String : AnyObject]!
override func viewDidLoad() {
super.viewDidLoad()
//creating button
let loginButton = LoginButton(readPermissions: [ .publicProfile, .userFriends, .email ])
loginButton.center = view.center
//adding it to view
view.addSubview(loginButton)
//if the user is already logged in
if let accessToken = FBSDKAccessToken.current(){
getFBUserData()
}
}
//when login button clicked
#objc func loginButtonClicked() {
let loginManager = LoginManager()
loginManager.logIn([ .publicProfile, .userFriends, .email ], viewController: self) { loginResult in
switch loginResult {
case .failed(let error):
print(error)
case .cancelled:
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
self.getFBUserData()
}
}
}
//function is fetching the user data
func getFBUserData(){
if((FBSDKAccessToken.current()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil){
self.dict = result as! [String : AnyObject]
print(result!)
print(self.dict)
}
})
}
}
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
/*
Check for successful login and act accordingly.
Perform your segue to another UIViewController here.
*/
let viewController = self.storyboard?.instantiateInitialViewController("StoryBoardID") as? UITableViewController
self.presentViewController(viewController, animated: true, completion: nil)
}
func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!) {
// Actions for when the user logged out goes here
}
}
Any help?
I am new to Swift, getting error for [.publicProfile].
Type of expression is ambiguous without more context error
Code:
let loginManager = LoginManager()
loginManager.loginBehavior = LoginBehavior.native;
loginManager.logIn([.publicProfile], viewController: self) { (loginResult) in
switch loginResult {
case .failed(let error):
print(error)
case .cancelled:
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
print("Logged in \(grantedPermissions) \(declinedPermissions) \(accessToken)")
}
}
Method Signature:
loginManager.logIn(<#T##permissions: [ReadPermission]##[ReadPermission]#>, viewController: <#T##UIViewController?#>, completion: <#T##((LoginResult) -> Void)?##((LoginResult) -> Void)?##(LoginResult) -> Void#>)
In the last updated FacebookLogin API you should add parameter name before the first parameter:
loginManager.logIn(readPermissions: [ .publicProfile], ...
I got it resolved as I was creating this method in Manager which subclass of NSObject class.
So passing self for viewController was giving me issue. So i fixed by passing fromViewController instead of self. That's all.
func facebookLogin(fromViewController:UIViewController) {
let loginManager = LoginManager()
loginManager.loginBehavior = LoginBehavior.native;
loginManager.logIn([.publicProfile], viewController: fromViewController) { (loginResult) in
switch loginResult {
case .failed(let error):
print(error)
case .cancelled:
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
print("Logged in \(grantedPermissions) \(declinedPermissions) \(accessToken)")
}
}
}
I added FBSDK 4.7 to my swift app and when it opens the safari view controller to login, and I try to tap "Done" without inputting anything into the email/password fields, the app breaks. It spits out "fatal error: unexpectedly found nil while unwrapping an Optional value"
How do I handle this error?
Current login code:
if let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager(){
fbLoginManager.logInWithReadPermissions(["email"],fromViewController:self,
handler:{(result:FBSDKLoginManagerLoginResult!,error:NSError!) -> Void in
if (error == nil){
let fbloginresult : FBSDKLoginManagerLoginResult = result
if(fbloginresult.grantedPermissions.contains("email"))
{
print("Logged in successfully")
self.getFBUserData()
//fbLoginManager.logOut()
}
}
else{
print("HELPPPPPPPPPP")
}
})
}
No need to assign the types of variable (result, error) :
Here is working code with Facebook 4.7 SDK | Swift 2 | Xcode 7.
#IBAction func btnFBLoginPressed(sender: AnyObject) {
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = FBSDKLoginBehavior.Web
fbLoginManager.logInWithReadPermissions(["email"], fromViewController: self, handler: { (result, error) -> Void in
if (error == nil){
let fbloginresult : FBSDKLoginManagerLoginResult = result
if fbloginresult.grantedPermissions != nil { //Here we have to check that the set contains value or not
if(fbloginresult.grantedPermissions.contains("email"))
{
self.getFBUserData()
fbLoginManager.logOut()
}
}
}
})
}
func getFBUserData(){
if((FBSDKAccessToken.currentAccessToken()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
if (error == nil){
print(result)
}
})
}
}
We have to check the grantedPermissions's Set is nil or not.
if fbloginresult.grantedPermissions != nil { //Here we have to check that the set contains value or not
