title: Unable to get the email id of the User when Log-in with Facebook SDK in iOS
body: <p>I am getting [null] value when I am fetching the user's email-id using below code.
  Also, I already set the permission to access the email like this.</p>
  
  <pre><code>{
  self.fbLoginButton.readPermissions = @[@"public_profile", @"email", @"user_friends"];
  }
  </code></pre>
  
  <p>Also Fetching the email details in delegate.</p>
  
  <pre><code>- (void)loginButton:(FBSDKLoginButton *)loginButton
  didCompleteWithResult:  (FBSDKLoginManagerLoginResult *)result
  error:  (NSError *)error
  {
      if ([FBSDKAccessToken currentAccessToken])
      {
          [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
           startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
               if (!error) {
                   NSLog(@"fetched user:%@", result);
                   NSLog(@"fetched user:%@ and Email : %@", result,result[@"email"]);
  
  
               }
           }];
      }
  
  }
  </code></pre>
  
  <p>Please provide any solution in this.</p>
