I am using facebook ios sdk 4.1
And i am using this code to get user's info after user click button and login
func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!) {
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
println("Error: \(error)")
}
else
{
var fbuseremail = result.valueForKey("email") as! NSString
var fbfirstname = result.valueForKey("first_name") as! NSString
var fblastname = result.valueForKey("last_name") as! NSString
var fbusername = result.valueForKey("name") as! NSString
//....more code
But result.valueForKey("email") and others returns nil
Any idea how to fix this ?
Get user info in facebook sdk 4.x swift
#IBAction func btnFBLoginPressed(sender: AnyObject) {
var fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager .logInWithReadPermissions(["email"], handler: { (result, error) -> Void in
if (error == nil){
var fbloginresult : FBSDKLoginManagerLoginResult = result
if(fbloginresult.grantedPermissions.containsObject("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){
println(result)
}
})
}
}
Output :
{
email = "ashishkakkad8#gmail.com";
"first_name" = Ashish;

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
Below is my code :-
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager .logInWithReadPermissions(["public_profile","user_birthday","email"], handler: { (result, error) -> Void in
if (error == nil)
{

}
}
})
}

if (error == nil)
{
print(result)
self.performSegueWithIdentifier("login_with_facebook_vc", sender: nil)
}
})
}
}
I am new in swift2. So i am unable to get facebook user_birthday, location.
Please help me.
I use this code to get email:
func getEmail() {
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"email"])
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
print("Error: \(error)")
}
else
{
print("fetched user: \(result)")
if let facebookEmail: String = result.valueForKey("email") as? String {
print("email is: \(facebookEmail)")
self.email = facebookEmail
}
}
})
}
Try this with birthday
I use the lastest Facebook SDK in swift. My problem is when I try to pass my Facebook name into a variable. There is my code :
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
{
// This variable is declared under my class declaration
self.userFacebook = result.valueForKey("name") as! String
println(self.userFacebook) //it's works, my Facebook name appear
}
})
}
But, when I try to use my variable "userFacebook" outsite of this function (returnUserData), the result is "nil".
I don't understand why my variable is set only in the function and not in my class.
Thanks
You pass parameter request what data is get for example get name.
request parameter like this
["fields": "id, name, first_name, last_name, picture.type(large), email"]
Try this code :
#IBAction func btnFBLoginPressed(sender: AnyObject) {
var fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager .logInWithReadPermissions(["email"], handler: { (result, error) -> Void in
if (error == nil){
var fbloginresult : FBSDKLoginManagerLoginResult = result
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){
println(result)
println(result["name"])
}
})
}
}
Following this tutorial, I have managed to make a Facebook Login Button working. However, it is assigning the button image automatically from the SDK and it is not customisable (as it is not getting created on Storyboard), so I am unable to use my own button image or text instead.
I believe this part of the code (in ViewDidLoad) is assigning the button:
let loginView : FBSDKLoginButton = FBSDKLoginButton()
self.view.addSubview(loginView)
loginView.center = self.view.center
loginView.readPermissions = ["public_profile", "email"]
loginView.delegate = self
What I need to do is creating a #IBOutlet Button on Storyboard and customise it from there. How can I do that?
Login with custom button and access token.
Get user info in facebook sdk 4.x
Swift
#IBAction func btnFBLoginPressed(sender: AnyObject) {
var fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.logInWithReadPermissions(["email"], fromViewController: self, handler: { (result, error) -> Void in
if (error == nil){
var fbloginresult : FBSDKLoginManagerLoginResult = result
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){
println(result)
}
})
}
}
Updated answer using the last Facebook SDK (01/05/2016) and Swift 2.1
Create a UIButton with Interface Builder or by code and link the action of that button with this:
#IBAction func loginFacebookAction(sender: AnyObject) {
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.logInWithReadPermissions(["email"], fromViewController: self) { (result, error) -> Void in
if (error == nil){
let fbloginresult : FBSDKLoginManagerLoginResult = result
if(fbloginresult.grantedPermissions.contains("email"))
{
self.getFBUserData()
}
}
}
}
The happy case of the previous code triggers the function self.getFBUserData() so you have to implement that function in the same file
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){
//everything works print the user data
print(result)
}
})
}
}
I did it successfully in xcode 7.3
#IBAction func fbLoginBtnAction(sender: AnyObject) {
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.logInWithReadPermissions(["email"], fromViewController: self, handler: {(result, error) -> Void in
if error == nil {
print("Logged in through facebook" )
self.getFBUserData()
}
else {
print("Facebook Login Error----\n",error)
}
}
)
}
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)
}
})
}
}

If you want to use the native button try this out:
let buttonText = NSAttributedString(string: "your text here")
facebookButton.setAttributedTitle(buttonText, for: .normal)
