Setting title of UINavigationbar not working

Question

I've looked through a few online tutorials, but nothing is working.

That's the code of my viewController:

import UIKit

class ViewController: UINavigationController {

    let textView = UITextView()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        // tried this
        self.navigationItem.title = "AAA"

        // and this
        self.title = "AAA"

        // and finally this
        self.parent?.title = "AAA"
    }
}

I don't understand why this isn't working (I haven't used a navigation bar before)

I didn't change anything in the main.storyboard.

Thanks for your answers.

Answer 1

First of all in your storyboard select your view controller and then

Editor -> Embed In -> Navigation Controller

then in your ViewController class add

self.title = "AAA"

in your viewDidLoad method and your code will look like:

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.title = "AAA"
    }
}

You need to replace UINavigationController with UIViewController
