iOS facebookSDK obtener usuario completo detalles

Question

Estoy usando el último FBSDK (usando 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)")


}

Cuando imprimo el usuario obtenido, solo obtengo el ID y el nombre. , pero solicité un permiso para correo electrónico, amigos y perfil, ¿qué ocurre?

Por cierto: moví este proyecto de mi macbook a otro macbook (porque formateé el mío) funcionó muy bien cuando estaba en el macbook en el que creé el proyecto, pero después de mover el proyecto (usando el clon de bitbucket) obtuve estos resultados .

En Swift 4.2 y 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)

            }
        }
    }

}

Answer 2

Según el nuevo SDK de Facebook, debe pasar los parámetros con 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)
        }
    })
}

Referencia de objeto de usuario: https://developers.facebook.com/docs/graph-api/reference/user

Con perfil público puedes obtener género:

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

Answer 3

Supongo que este código debería ayudarte a obtener los detalles requeridos.

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)")



        }
    })

Swift 4

Un ejemplo en Swift 4 que también muestra cómo analizar correctamente los campos individuales del resultado:

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)")
                }
            }
        }
    }
}
