iOS facebookSDK get user full details - ios

Question

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

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)")
}
})

In Swift 4.2 and Xcode 10.1
#IBAction func onClickFBSign(_ sender: UIButton) {
if let accessToken = AccessToken.current {
// User is logged in, use 'accessToken' here.
print(accessToken.userId!)
print(accessToken.appId)
print(accessToken.authenticationToken)
print(accessToken.grantedPermissions!)
print(accessToken.expirationDate)
print(accessToken.declinedPermissions!)
let request = GraphRequest(graphPath: "me", parameters: ["fields":"id,email,name,first_name,last_name,picture.type(large)"], accessToken: AccessToken.current, httpMethod: .GET, apiVersion: FacebookCore.GraphAPIVersion.defaultVersion)
request.start { (response, result) in
switch result {
case .success(let value):
print(value.dictionaryValue!)
case .failed(let error):
print(error)
}
}
let storyboard = self.storyboard?.instantiateViewController(withIdentifier: "SVC") as! SecondViewController
self.present(storyboard, animated: true, completion: nil)
} else {
let loginManager=LoginManager()
loginManager.logIn(readPermissions: [ReadPermission.publicProfile, .email, .userFriends, .userBirthday], 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), \n \(declinedPermissions), \n \(accessToken.appId), \n \(accessToken.authenticationToken), \n \(accessToken.expirationDate), \n \(accessToken.userId!), \n \(accessToken.refreshDate), \n \(accessToken.grantedPermissions!)")
let request = GraphRequest(graphPath: "me", parameters: ["fields": "id, email, name, first_name, last_name, picture.type(large)"], accessToken: AccessToken.current, httpMethod: .GET, apiVersion: FacebookCore.GraphAPIVersion.defaultVersion)
request.start { (response, result) in
switch result {
case .success(let value):
print(value.dictionaryValue!)
case .failed(let error):
print(error)
}
}
let storyboard = self.storyboard?.instantiateViewController(withIdentifier: "SVC") as! SecondViewController
self.navigationController?.pushViewController(storyboard, animated: true)
}
}
}
