I need to create navigation controller and navigation bar programatically. I need to change top and objects measurement and place. My navigation bar top = 74 and merchandise measurement = 50×50. Additionally merchandise high area = 12 and backside = 12. I attempting to do it with this code:
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, choices connectionOptions: UIScene.ConnectionOptions) {
if let windowScene = (scene as? UIWindowScene) {
let window = UIWindow(windowScene: windowScene)
let navigationController = UINavigationController()
let viewController = ViewController()
navigationController.viewControllers = [viewController]
window.rootViewController = navigationController
self.window = window
window.makeKeyAndVisible()
}
}
ViewController
override func viewDidAppear(_ animated: Bool) {
tremendous.viewDidAppear(animated)
self.navigationController?.navigationBar.backgroundColor = .grey
self.navigationController?.navigationBar.body.measurement.top = 74
navigationItem.backBarButtonItem = UIBarButtonItem(title: "", model: .plain, goal: nil, motion: nil)
let menuBtn = UIButton(sort: .customized)
menuBtn.body = CGRect(x: 0.0, y: 12.0, width: 50, top: 50)
menuBtn.setImage(UIImage(named:"mute"), for: .regular)
let menuBarItem = UIBarButtonItem(customView: menuBtn)
menuBarItem.customView?.widthAnchor.constraint(equalToConstant: 50).isActive = true
menuBarItem.customView?.heightAnchor.constraint(equalToConstant: 50).isActive = true
menuBarItem.setBackgroundVerticalPositionAdjustment(12.0, for: .default)
self.navigationItem.rightBarButtonItem = menuBarItem
}
Nevertheless it does not work. I do not see the peak of the navigation bar modified, nor the dimensions and place of the navigation buttons. The way to clear up an issue?
