@interface TutorialViewController .. does it subclass UIViewController ? – Shubhank Jun 16 '16 at 17:36
@Shubhank Sure. interface TutorialViewController : UIViewController. – Lisa Jun 20 '16 at 02:27
can you upload the project on github ? or maybe mail so that one can look over it ? – Shubhank Jun 20 '16 at 08:31
