Hi to my fellow developers
Just a simple question. How can I get the data of user through Facebook Graph API after login in app?
There's a sample in Facebook Documentation, but its not working.
let permisions = ["public_profile" ,"email" ,"user_birthday"]
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.logInWithReadPermissions(permisions, fromViewController: vc) { (result, error) -> Void in
if (error == nil) {
if result.isCancelled {
//do error handling for canceled
} else {
let fbLoginResult : FBSDKLoginManagerLoginResult = result
let facebookToken = fbLoginResult.token.tokenString
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
if (error != nil){
// handle error
}
let email = result.valueForKey("email") as? String ?? ""
let firstName = result.valueForKey("first_name") as? String ?? ""
let lastName = result.valueForKey("last_name") as? String ?? ""
// do stuffs with email or first name or last name
})
this is swift version 2.3 but with little modification it will convert to swift 3

ERROR MESSAGE:
Invalid Scopes: user_birthday, user_photos, user_gender. This message
is only shown to developers
After Facebook update in their api I get invalid scope messages for user_birthday, user_photos, user_gender. I haven't submitted my app for a login review, however, as an admin of the app I shouldn't be having any errors related to permissions. What could I possibly be doing wrong?
FBSDKLoginManager().logIn(withReadPermissions: ["email", "public_profile", "user_birthday", "user_photos", "user_gender"], from: self) { (result, err) in
print("open facebook safari")
if (err != nil) {
print("Fb Login Failed", err ?? "")
self.dismiss(animated: true, completion: nil)
}
self.handleFirebase()
}
FBSDKGraphRequest(graphPath: "/me", parameters: ["fields": "id, name, first_name, last_name, gender, birthday, picture.width(400).height(400)"]).start(completionHandler: { (connection, result, error) in
if let error = error {
print(error.localizedDescription)
} else {
if let userData = result as? NSDictionary {
self.firstName = userData.object(forKey: "first_name") as? String
self.gender = userData.object(forKey: "gender") as? String
self.birthday = userData.object(forKey: "birthday") as? String ?? ""
let pictureDictionary = userData.object(forKey: "picture") as! NSDictionary
let pictureSubDictionary = pictureDictionary.object(forKey: "data") as! NSDictionary
self.userProfileUrl = pictureSubDictionary.object(forKey: "url") as! String
}
}
I am struggling with the issue of Facebook login, Yesterday Facebook login working correctly but today when I run my app it's not working don't know why, why it's not working suddenly I already configured all things related to Facebook login in Facebook develop console everything is configured
Please help me out if you have any idea, I already enable Keychain sharing also.
Code for Facebook Login
#IBAction func onClickFacebookLoginAction(_ sender: Any) {
var message = String()
if Reachability.isConnectedToNetwork() == true{
let loginView:FBSDKLoginManager = FBSDKLoginManager()
loginView.loginBehavior = FBSDKLoginBehavior.web
loginView.logIn(withReadPermissions: ["email","public_profile","user_friends"], from: self, handler: { (result, error) in
if(error != nil){
print("Error while try to login with facebook-\(error?.localizedDescription)")
}else if (result?.isCancelled)!{
print("User cancel the facebook login")
}else{
if result?.grantedPermissions != nil{
if (result?.grantedPermissions .contains("email"))!{
self.ShowProgressHUD()
self.fetchUserInfo()
}else{
message = message.appending("Facebook email permission error")
self.showAlertMessage(message: message, title: "")
}
}
}
})
}
}
func fetchUserInfo() -> Void {
if (FBSDKAccessToken.current() != nil) {
let graphRequest:FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "/me", parameters:["fields": "id, first_name, last_name, name, email, picture"])
graphRequest.start(completionHandler: { (connection, result, error) in
if(error != nil){
self.showAlertMessage(message: (error?.localizedDescription)!, title: "")
}
else
{
print("Result is:\(result)")
self.dictionary = result as! [String : AnyObject]
let name = self.dictionary["name"] as!String
let email = self.dictionary["email"] as! String
let token = FBSDKAccessToken.current().tokenString
print("name is -\(name)")
print("email is -\(email)")
print("token is -\(token)")
DispatchQueue.main.async {
let SelectionViewObj = self.storyboard?.instantiateViewController(withIdentifier: "ViewController") as! ViewController
self.navigationController?.pushViewController(SelectionViewObj, animated: true)
}
}
})
}
}
This is the code i am using to authenticate facebook.its working like a charm.Just check or replace with this.
self.fbLoginManager = FBSDKLoginManager.init()
fbLoginManager.loginBehavior = FBSDKLoginBehavior.web
self.fbLoginManager.logIn(withReadPermissions: ["email"], from: self) { (result, error) -> Void in
if (error == nil) {
let fbloginresult : FBSDKLoginManagerLoginResult = result!
if fbloginresult.grantedPermissions != nil && fbloginresult.grantedPermissions.contains("email") {
if((FBSDKAccessToken.current()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id, first_name, last_name, email, gender, birthday, location"]).start(completionHandler: { (connection, result, error) -> Void in
if error != nil {
print(error?.localizedDescription ?? "error in facebook login...!")
return
}
if let dict = result as? NSDictionary {
print("facebook login result --->\n\(dict)")
guard let id = dict["id"] else {
print("Ooops... id = nil")
return
}
// let firstName: String = dict["first_name"] as? String ?? ""
// let lastName : String = dict["last_name"] as? String ?? ""
// let email : String = dict["email"] as? String ?? ""
self.fbLoginManager.logOut()
}
})
}
} else {
print("facebook ---> login canceled")
}
} else {
print(error?.localizedDescription ?? "facebook login has error")
}
}
This is how I used to log in with Facebook,
#IBAction func act_loginFB(_ sender: UIButton) {
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.logIn(withReadPermissions: ["public_profile", "email",], from: self) { (result, error) -> Void in
if (error == nil){
let fbloginresult : FBSDKLoginManagerLoginResult = result!
if(fbloginresult.grantedPermissions.contains("email"))
{
self.getFBUserData()
}
}
}
}
func getFBUserData(){
if((FBSDKAccessToken.current()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil){
//everything works print the user data
print(result)
let data: [String:AnyObject] = (result as? [String : AnyObject])!
print(data)
let email: String = data["email"]! as! String
print(email)
}
})
}
}
Check you added the correct FacebookAppID and FacebookDisplayName in the info.plist
I am working with iOS 9.2 & Swift 2.1 & FBSDKVersion: 4.7.0.
I tried with Graph API Explorer, at that time I am getting the desired output.
The converted code is in Objective-C and I changed it to Swift.
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "/me", parameters: ["fields": "hometown"], HTTPMethod: "GET")
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil){
print("Error: \(error)")
}
else{
print("fetched details: \(result)")
})
See below example and add hometown option into "fields" parameter of FBSDKGraphRequest object and also change:
func fetchUserProfile()
{
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id, email, name, picture.width(480).height(480)"])
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
print("Error took place: \(error)")
}
else
{
print("Print entire fetched result: \(result)")
let id : NSString = result.valueForKey("id") as! String
print("User ID is: \(id)")
if let userName = result.valueForKey("name") as? String
{
self.userFullName.text = userName
}
if let profilePictureObj = result.valueForKey("picture") as? NSDictionary
{
let data = profilePictureObj.valueForKey("data") as! NSDictionary
let pictureUrlString = data.valueForKey("url") as! String
let pictureUrl = NSURL(string: pictureUrlString)
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {
let imageData = NSData(contentsOfURL: pictureUrl!)
dispatch_async(dispatch_get_main_queue()) {
if let imageData = imageData
{
let userProfileImage = UIImage(data: imageData)
self.userProfileImage.image = userProfileImage
self.userProfileImage.contentMode = UIViewContentMode.ScaleAspectFit
}
}
}
}
}
})
}

Fetching user details from Facebook in iOS
Iam using the last FBSDK (using swift)
// MARK: sign in with facebook
func signInWithFacebook()
{
if (FBSDKAccessToken.currentAccessToken() != nil)
{
// User is already logged in, do work such as go to next view controller.
println("already logged in ")
self.returnUserData()
return
}
var faceBookLoginManger = FBSDKLoginManager()
faceBookLoginManger.logInWithReadPermissions(["public_profile", "email", "user_friends"], handler: { (result, error)-> Void in
//result is FBSDKLoginManagerLoginResult
if (error != nil)
{
println("error is \(error)")
}
if (result.isCancelled)
{
//handle cancelations
}
if result.grantedPermissions.contains("email")
{
self.returnUserData()
}
})
}
func returnUserData()
{
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
println("Error: \(error)")
}
else
{
println("the access token is \(FBSDKAccessToken.currentAccessToken().tokenString)")
var accessToken = FBSDKAccessToken.currentAccessToken().tokenString
var userID = result.valueForKey("id") as! NSString
var facebookProfileUrl = "http://graph.facebook.com/\(userID)/picture?type=large"
println("fetched user: \(result)")
}
when I print the fetched user I get only the id and the name ! ,
but i requested a permission for email and friends and profile ,
what's wrong ???
BTW : I moved this project from my macbook to another macbook ( because I formatted mine) it worked very well when it was at the the macbook which I created the project on , but after moving the project (using bitbucket clone) I got this results .
As per the new Facebook SDK, you must have to pass the parameters with the FBSDKGraphRequest
if((FBSDKAccessToken.currentAccessToken()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
if (error == nil){
println(result)
}
})
}
Documentations Link : https://developers.facebook.com/docs/facebook-login/permissions/v2.4
User object reference : https://developers.facebook.com/docs/graph-api/reference/user
With public profile you can get gender :
public_profile (Default)
Provides access to a subset of items that are part of a person's public profile. A person's public profile refers to the following properties on the user object by default:
id
name
first_name
last_name
age_range
link
gender
locale
timezone
updated_time
verified
Swift 4
An example in Swift 4 that also shows how to correctly parse out the individual fields from the result:
func fetchFacebookFields() {
//do login with permissions for email and public profile
FBSDKLoginManager().logIn(withReadPermissions: ["email","public_profile"], from: nil) {
(result, error) -> Void in
//if we have an error display it and abort
if let error = error {
log.error(error.localizedDescription)
return
}
//make sure we have a result, otherwise abort
guard let result = result else { return }
//if cancelled nothing todo
if result.isCancelled { return }
else {
//login successfull, now request the fields we like to have in this case first name and last name
FBSDKGraphRequest(graphPath: "me", parameters: ["fields" : "first_name, last_name"]).start() {
(connection, result, error) in
//if we have an error display it and abort
if let error = error {
log.error(error.localizedDescription)
return
}
//parse the fields out of the result
if
let fields = result as? [String:Any],
let firstName = fields["first_name"] as? String,
let lastName = fields["last_name"] as? String
{
log.debug("firstName -> \(firstName)")
log.debug("lastName -> \(lastName)")
}
}
}
}
}
I guess this code should help you get the required details
Swift 2.x
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
print("Error: \(error)")
}
else
{
print("fetched user: \(result)")
let userName : NSString = result.valueForKey("name") as! NSString
print("User Name is: \(userName)")
let userID : NSString = result.valueForKey("id") as! NSString
print("User Email is: \(userID)")
}
})

I'm trying to get the user's email address with the followings:
fbLoginManager.logInWithReadPermissions(["email", "public_profile"], handler: { (loginResult, error) -> Void in
if error != nil {
//handle error
} else if loginResult.isCancelled {
//handle cancellation
} else {
//Logged in
self.loggedinUser.fbToken = FBSDKAccessToken.currentAccessToken().tokenString
var graphReq = FBSDKGraphRequest(graphPath: "me", parameters: nil).startWithCompletionHandler { (connection, result, error) -> Void in
if let user = result as? NSDictionary {
var email = result.objectForKey("email") as? String
var name = result.objectForKey("name") as? String
self.loggedinUser.email = email ?? nil
self.loggedinUser.fullName = name ?? nil
}
}
}
})
But in the loginResult object the user's email is not sent. Any idea how to solve this?
thanks
You must provide in the parameters what you want to get:
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
For example to get more than one field:
parameters: ["fields": "id, name, email, picture.type(large)"]
