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

This is how I solve the problem in Objective C.

You can call dismissViewControllerAnimated:NO on your self.navigationController itself.

Objective C

[self.navigationController dismissViewControllerAnimated:NO completion:nil];

Swift

self.navigationController.dismissViewControllerAnimated(false, completion: nil)

Answer 2

You can use the following to correctly dismiss a UINavigationController that's presented as a modal in Swift 4:

self.navigationController?.popViewController(animated: true)

Answer 3

No need to have member for navController. Use following code to present your MessagesViewController.

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

Your dismiss view controller code will be

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

Answer 4

In Swift 3 this is achieved with:

self.navigationController?.dismiss(animated: true, completion: nil)

Answer 5

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)
}

Answer 6

Try this

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