Get Email and Name Facebook Sdk V4.4.0 Swift

Get email and name Facebook SDK v4.4.0 Swift

I've used fields in android, so I figured to try it in iOS as well, and it works.

let req = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"email,name"], tokenString: accessToken.tokenString, version: nil, HTTPMethod: "GET")
   req.startWithCompletionHandler({ (connection, result, error : NSError!) -> Void in
       if(error == nil) {
            print("result \(result)")
       } else {
            print("error \(error)")
       }
   }
)

result will print:

result {
   email = "email@example.com";
   id = 123456789;
   name = "Your Name";
}

Found that these fields are equal to the User endpoint, see this link where you can see all the fields that you can get.

Update for Swift 4 and above

let r = FBSDKGraphRequest(graphPath: "me",
                          parameters: ["fields": "email,name"],
                          tokenString: FBSDKAccessToken.current()?.tokenString,
                          version: nil,
                          httpMethod: "GET")

r?.start(completionHandler: { test, result, error in
    if error == nil {
        print(result)
    }
})

Update for Swift 5 with FBSDKLoginKit 6.5.0

guard let accessToken = FBSDKLoginKit.AccessToken.current else { return }
let graphRequest = FBSDKLoginKit.GraphRequest(graphPath: "me",
                                              parameters: ["fields": "email, name"],
                                              tokenString: accessToken.tokenString,
                                              version: nil,
                                              httpMethod: .get)
graphRequest.start { (connection, result, error) -> Void in
    if error == nil {
        print("result \(result)")
    }
    else {
        print("error \(error)")
    }
}

[Facebook-iOS-SDK 4.0]How to get user email address from FBSDKProfile

To fetch email you need to utilize the graph API, specifically providing the parameters field populated with the fields you want. Take a look at Facebook's Graph API explore tool, which can help to figure out the queries. https://developers.facebook.com/tools/explorer

The code that worked for me to fetch email is the following, which assumes you are already logged in:

    NSMutableDictionary* parameters = [NSMutableDictionary dictionary];
    [parameters setValue:@"id,name,email" forKey:@"fields"];

    [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:parameters]
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                  id result, NSError *error) {
         aHandler(result, error);
     }];

        if let res = values {
            if let response = res as? [String: Any] {
                let username = response["name"]
                let email = response["email"]

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)
        }
    })
}

   if let strFirstName = dic["first_name"] as? String, let strLastName = dic["last_name"] as? String
       {
          print("\(strFirstName) \(strLastName)")
       }
 }
