FBSDK (New Facebook SDK 4.0) Implementation is not working for Login with Facebook

Question

I am using this following block which is mentioned in Facebook Developer. But when my App callbacks from Browser then it is always returning Cancelled result.

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:@[@"email"]     
        handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
  if (error) {
        // Process error
   }
  else if (result.isCancelled) {
        // Handle cancellations
   }
   else {
       // If you ask for multiple permissions at once, you
       // should check if specific permissions missing
       if ([result.grantedPermissions containsObject:@"email"]) {
        // Do work
       }
  }
 }];

Answer 1

You cant get Email id from Facebook Login....why???

If your Facebook account registered using "Mobile Number", and you do not have Email in same account.

Check this scenario. This might be happening, We cant blame for it to FBSDK.

Hope this will clear some points.
