Parse and Facebook sdk 4.1 login and signup returning "User Cancelled Login" Objective-C

Question

I recently updated my Parse SDK to 1.7.4 and Facebook SDK to 4.1, but for getting user data a code that was working in Facebook SDK 3.22.2 is not working in Facebook SDK 4.1. I'm getting error:

Unknown type name 'FBRequest'; did you mean 'SKRequest'?

- (void)requestFacebook:(PFUser *)user
{
FBRequest *request = [FBRequest requestForMe];
[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error)
 {
     if (error == nil)
     {
         NSDictionary *userData = (NSDictionary *)result;
         [self processFacebook:user UserData:userData];
     }
     else
     {
         [PFUser logOut];
         [ProgressHUD showError:@"Failed to fetch Facebook user data."];
     }
 }];
}
