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
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"])
}
})
}
}
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)")
}
})
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!)")

I'm trying to get data on a facebook user by using his ID.
I have an array of facebook user ids called IDs, and I set the graphPath to: "/IDs[0]", when I run the code I get an error.
cam you tell me whats wrong with my code?
var pathIs: String = "/"
pathIs += IDs[0]
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: pathIs, parameters: ["fields": "id, name, birthday, picture.type(small)"])
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
println("Error: \(error)")
}
else
{
println("fetched user: \(result)")
}
})
Thanks!
I am wondering if there is typed access to the result that comes back from a FBSDKGraphRequest?
For example, I make the request for my own profile as follows:
var theRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
theRequest.startWithCompletionHandler({ (connection: FBSDKGraphRequestConnection!, result: AnyObject!, error: NSError!) -> Void in
// GET TYPED ACCESS TO MY ID
println(result.id)
// GET TYPED ACCESS TO MY GENDER
println(result.gender)
}
)
This doesn't work, because result is currently of type AnyObject, and AnyObject does not have fields for the info returned. Basically I am wondering if there is a class / protocol that I can cast result to so that I have typed access. Is this possible? It seems like its not from what I have researched so far.
Create a dictionary :
class ViewController: UIViewController {
var dict : NSDictionary!
}
Fetching the data :
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){
self.dict = result as NSDictionary
println(self.dict)
NSLog(self.dict.objectForKey("picture")?.objectForKey("data")?.objectForKey("url") as String)
}
})
}
Output should be :
{
email = "ashishkakkad8#gmail.com";
"first_name" = Ashish;
id = 910855688971343;
"last_name" = Kakkad;
name = "Ashish Kakkad";
picture = {
data = {
"is_silhouette" = 0;
