如何在uiviewController中创建一个uinavigation controll，以程序为快速

我是在Swift故事板中为iOS创建一个多门一应用程序。我想在uiviewController中以编程方式添加一个UinavigationController，或者如果有故事板的可能性，我为此做了很多研究，我还没有发现任何有价值的东西。

我也有一个创建一个，但不负责对于所有手机和按钮不起作用，

override func viewDidLoad() {
    super.viewDidLoad()
    let height: CGFloat = 50
    let width = self.view.frame.width
    let navbar = UINavigationBar(frame: CGRect(x: 0, y: 40, width: width, height: height))
    navbar.backgroundColor = UIColor.white
    navbar.delegate = self

    let navItem = UINavigationItem()
    navItem.title = "Last Call"
    navItem.rightBarButtonItem = UIBarButtonItem(title: "Add New", style: .plain, target: self, action: nil)

    navbar.items = [navItem]

    view.addSubview(navbar)

    self.view.frame = CGRect(x: 0, y: height, width: width, height: (UIScreen.main.bounds.height - height))

}

我在视图控制器中嵌入了导航控制器，这就是它的外观这就是它的外观

I´m creating a multiScene app for iOS in Swift Storyboard.
I want to add a UINavigationController programmatically in UIViewController or if there is possible with storyboard, I have made a lot a research for this and I haven´t find anything valuable.

In each view controller I want to add the Navigation Controller

Also I have create one but is not responsible for all phones and the button does not work

override func viewDidLoad() {
    super.viewDidLoad()
    let height: CGFloat = 50
    let width = self.view.frame.width
    let navbar = UINavigationBar(frame: CGRect(x: 0, y: 40, width: width, height: height))
    navbar.backgroundColor = UIColor.white
    navbar.delegate = self

    let navItem = UINavigationItem()
    navItem.title = "Last Call"
    navItem.rightBarButtonItem = UIBarButtonItem(title: "Add New", style: .plain, target: self, action: nil)

    navbar.items = [navItem]

    view.addSubview(navbar)

    self.view.frame = CGRect(x: 0, y: height, width: width, height: (UIScreen.main.bounds.height - height))

}

I have embed a Navigation controller in my view controller and this is how it looks like
This is how it looks like

也许请查看“显示和隐藏视图控制器”，其中解释了某些导航概念：

使用故事板时，您应该能够使用SEGUE从一个视图控制器导航到另一个视图控制器。

我不完全理解您想要的东西，但让我解释一些事情：

您不能直接在 uinavigationController 中直接添加 uiviewController ，我们将 ViewController 而不是：

 让ViewController =某些ViewController //您的ViewController
让NavigationController = uinavigationController（rootviewController：viewController）//这成为要使用的ViewController。 
self.present（navigation controller）//使用示例

我们不包装所有<代码> uiviewController 在 uinavigationController ，只有导航父母。

I don't fully understand what you want, but let me explain a few things:

You can't add a UINavigationController directly in a UIViewController, we wrap the ViewController instead:

let viewController = some ViewController //your ViewController
let navigationController = UINavigationController(rootViewController: viewController)//this becomes the ViewController to be used. 
self.present(navigationController)//example of usage
