Creating a navigationController programmatically (Swift)

I've been trying to redo the work on my app programmatically. (Without the use of storyboards)

I'm almost done, except making the navigation controller manually.

Currently, I only have 1 viewcontroller. And of course the appDelegate

The navigation Controller, will be used throughout all pages in the application.

If anyone could help me out, or send a link to some proper documentation for doing this programmatically it would be greatly appreciated.

EDIT:

I forgot to mention it's in Swift.

Solution

  • In AppDelegate.swift

    Swift 1, 2:

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
   self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
   var nav1 = UINavigationController()
   var mainView = ViewController(nibName: nil, bundle: nil) //ViewController = Name of your controller
   nav1.viewControllers = [mainView]
   self.window!.rootViewController = nav1
   self.window?.makeKeyAndVisible()
}

    Swift 4+: and Swift 5+

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
   self.window = UIWindow(frame: UIScreen.main.bounds)
   let nav1 = UINavigationController()
   let mainView = ViewController(nibName: nil, bundle: nil) //ViewController = Name of your controller
   nav1.viewControllers = [mainView]
   self.window!.rootViewController = nav1
   self.window?.makeKeyAndVisible()
}
