How to correctly dismiss a UINavigationController that's presented as a modal?

Question

In my TabBarViewController, I create a UINavigationController and present it as a modal.

var navController =  UINavigationController()
let messageVC         


        

Answer 1

I suggest you use the other initializer for your UINavigationController:

let messageVC = self.storyboard?.instantiateViewControllerWithIdentifier("MessagesViewController") as! MessagesViewController
let navController = UINavigationController(rootViewController: messageVC)
self.presentViewController(self.navController, animated: true, completion: nil)

To dimiss, simply do

func swipedRightAndUserWantsToDismiss() {
  self.navigationController.dismissViewControllerAnimated(true, completion: nil)
}
