Get Facebook user details with swift and parse - swift

Question

i need to get the Facebook user information details when i login a new user through parse. at present i am logging in the new user below. can't seem to get the user details though. I've seen some code written on objective - c. most of the functions don't work anymore
The Facebook iOS sdks i am running is v4.3.0.
#IBAction func facebookButton(sender: AnyObject) {
PFFacebookUtils.logInInBackgroundWithReadPermissions(permissions) {
(user: PFUser?, error: NSError?) -> Void in
if let user = user {
if user.isNew {
println("User signed up and logged in through Facebook!")
} else {
println("User logged in through Facebook!")
}
} else {
println("Uh oh. The user cancelled the Facebook login.")
}
}
}

Answer 1

To get the user details you have to send a FBSDKGraphRequest after the login request.
This can be done inside the if let user = user {...} block.
// Create request for user's Facebook data
let request = FBSDKGraphRequest(graphPath:"me", parameters:nil)
// Send request to Facebook
request.startWithCompletionHandler {
(connection, result, error) in
if error != nil {
// Some error checking here
}
else if let userData = result as? [String:AnyObject] {
// Access user data
let username = userData["name"] as? String
// ....
}
}

For the new Facebook API and version of Swift 3.1 you can do something like this:
if((FBSDKAccessToken.current()) != nil) {
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id,name,first_name,last_name,email"]).start(completionHandler: {(connection, result, error) -> Void in
if(error != nil) {
print("Some error occurred.");
} else {
print(result!)
}
})
}
