presenting ViewController with NavigationViewController swift

Question

I have system "NavigationViewController -> MyViewController", and I programmatically want to present MyViewController inside a third view controller. The problem is that I don't have navigation bar in MyViewController after presenting it. Can you help me?

var VC1 = self.storyboard.instantiateViewControllerWithIdentifier("MyViewController") as ViewController self.presentViewController(VC1, animated:true, completion: nil) 

Answer 1

Calling presentViewController presents the view controller modally, outside the existing navigation stack; it is not contained by your UINavigationController or any other. If you want your new view controller to have a navigation bar, you have two main options:

Option 1. Push the new view controller onto your existing navigation stack, rather than presenting it modally:

let VC1 = self.storyboard!.instantiateViewControllerWithIdentifier("MyViewController") as! ViewController self.navigationController!.pushViewController(VC1, animated: true) 

Option 2. Embed your new view controller into a new navigation controller and present the new navigation controller modally:

let VC1 = self.storyboard!.instantiateViewControllerWithIdentifier("MyViewController") as! ViewController let navController = UINavigationController(rootViewController: VC1) // Creating a navigation controller with VC1 at the root of the navigation stack. self.present(navController, animated:true, completion: nil) 

Bear in mind that this option won't automatically include a "back" button. You'll have to build in a close mechanism yourself.

Which one is best for you is a human interface design question, but it's normally clear what makes the most sense.

let VC1 = self.storyboard!.instantiateViewController(withIdentifier: "MyViewController") as! MyViewController let navController = UINavigationController(rootViewController: VC1) self.present(navController, animated:true, completion: nil)
