I want user to login before going to split view controller. I tried to create a push segue then call the performSegueWithIdentifier. An error comes out. It says "Terminating app due to uncaught exception 'NSGenericException', reason: 'Could not find a navigation controller for segue 'fromLoginToTask'. Push segues can only be used when the source controller is managed by an instance of UINavigationController.'"
Thanks.
