iOS FBSDKLoginManager获取电子邮件

我在这里学习了关于SDK的Facebook教程：

我的问题是，我可以获得用户信息，但我无法获得电子邮件，它不在当前配置文件中。我有名字、姓氏、用户id等

在哪里可以找到电子邮件字段，因为当我这样做时 “如果（[result.grantedPermissions containsObject:@”email“]）”

---

它告诉我用户已授予该电子邮件。

您是否尝试过以下操作：

if ([result.grantedPermissions containsObject:@"email"]) { 
    NSLog(@"Granted all permission");
    if ([FBSDKAccessToken currentAccessToken]) {
        [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
           if (!error) {
               NSLog(@"%@",result);
           }
        }];
    }
} else {
    NSLog(@"Not granted");
}

    }
} else {
    NSLog(@"Not granted");
}

添加一个参数“email”以获取当前用户的电子邮件。我认为SDK版本4.9中的“字段”参数对于获取用户电子邮件是必需的。（但我没有检查以前的SDK版本）

让用户知道您请求了电子邮件的权限

 let requestMe:FBSDKGraphRequest = FBSDKGraphRequest.init(graphPath: "/me", parameters: ["fields": "id,email, first_name, last_name, gender, picture"])


    let connection : FBSDKGraphRequestConnection = FBSDKGraphRequestConnection()



            connection.add(requestMe, completionHandler: { (con, results, error) in

                //access_token

                if ((error) == nil)

                {


                    let dic = results as! NSDictionary

                    let email = (dic.value(forKey: "email"))




                }
                else

                {


                }

            })


            connection.start()

            connection.start()
