I am using FBLogInView to implement FBLogin. loginViewFetchedUserInfo not getting called - iphone

Question

I have spent several hours. Read up everything relevant I could find on the web, but haven't been able to resolve this. I am using FBLoginView per instructions provided in https://developers.facebook.com/docs/ios/login-ui-control/
I can see FBLogin button. I click on it. It logs me in. I see callbacks loginViewShowingLoggedInUser and loginViewShowingLoggedOutUser getting called. The problem is loginViewFetchedUserInfo not getting called. So, I am unable to get any information about the user (such as name, userID, email etc).
Here is the code I am using:
CGRect loginFrame=CGRectMake(MARGIN,currentFrame.size.height-LOGINBUTTONHEIGHT,50 , 20);//width, height don't matter
FBLoginView * FBLoginView1 = [[FBLoginView alloc] init];
FBLoginView1.readPermissions = #[#"email",
#"basic_info",
#"user_location",
#"user_birthday",
#"user_likes"];
FBLoginView1.frame = loginFrame;
FBLoginView1.delegate = self;
[[self view] addSubview:FBLoginView1];
[FBLoginView1 sizeToFit];
Please help me.

Answer 1

It may help: I have get the same issue. For me the solution was I did not correctly assign the delegate.
Programmatically, Facebook propose you to
FBLoginView *loginView = [[FBLoginView alloc] init];
loginView.delegate = self;
But as I have set up the view via the storyboard, I could not do that. So in the inspector connector, I connect the delegate outlet to the File's Owner (I just wired the outlet the scene).
Hope it helps :)

I found the solution. Actually, loginViewFetchedUserInfo is called after loginViewShowingLoggedInUser. I was not getting loginViewFetchedUserInfo because I was dismissing modalviewcontroller from loginViewShowingLoggedInUser. So, it was not around to get loginViewFetchedUserInfo. If I don't dismiss the modalviewcontroller, I get loginViewFetchedUserInfo.
Here are the details of the solution.
I am creating FBLoginView in ViewDidLoad of a LoginViewcontroller (name of the class I implemented).
I set the delegate when I create FBLoginView (inside ViewDidLoad function)
LoginViewController is presented using presentViewController function.
The problem was happening because I was dismissing the view controller in loginViewShowingLoggedInUser. So it was not around to receive loginViewFetchedUserInfo ( loginViewFetchedUserInfo is called after loginViewShowingLoggedInUser).
The solution that worked for me is to dismiss LoginViewcontroller from loginViewFetchedUserInfo.
Hope the details helps others.

I had the same problem. In my case, delegate was not set properly. Ensure you the following lines in logincontroller:
FBLoginView *loginView = [[FBLoginView alloc] init];
loginView.delegate = self;
