Is it possible to have only large titles in the navigation bar? - swift

Question

I want my application to have large titles, however, when the user scrolls, I don't want the regular/normal navigation bar to appear. I just want the large bar to scroll up along with the tableview. Is this possible without making custom views in the navigation bar? I have done it successfully with custom views, but it isn't as fluid and putting a UISearchController inside is a pain.
func createNavController(vc: UIViewController, title: String, image: UIImage, tag: Int) -> UINavigationController {
let navController = UINavigationController(rootViewController: vc)
navController.navigationBar.prefersLargeTitles = true
navController.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
navController.navigationBar.shadowImage = UIImage()
navController.navigationBar.tintColor = .headerColor
navController.tabBarItem = UITabBarItem(title: title, image: image.withRenderingMode(.alwaysTemplate), tag: tag)
navController.navigationBar.topItem?.title = title
navController.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.headerColor, .font: UIFont.customHeaderFont(size: 25)]
navController.navigationBar.largeTitleTextAttributes = [.foregroundColor: UIColor.headerColor, .font: UIFont.customHeaderFont(size: 40)]
// let titleLabel = UILabel()
// titleLabel.text = title
// titleLabel.textColor = .headerColor
// titleLabel.font = UIFont.customHeaderFont(size: navController.navigationBar.frame.height - 5)
// navController.navigationBar.addSubview(titleLabel)
// titleLabel.anchor(top: nil, left: navController.navigationBar.leftAnchor, bottom: nil, right: nil, paddingTop: 0, paddingLeft: 20, paddingBottom: 0, paddingRight: 0, width: 0, height: 0)
// titleLabel.centerYAnchor.constraint(equalTo: navController.navigationBar.centerYAnchor).isActive = true
return navController
}

Use my extension iOS 13 Swift 5 tested
extension UIViewController {
func configureNavigationBar(largeTitleColor: UIColor, backgoundColor: UIColor, tintColor: UIColor, title: String, preferredLargeTitle: Bool) {
if #available(iOS 13.0, *) {
let navBarAppearance = UINavigationBarAppearance()
navBarAppearance.configureWithOpaqueBackground()
navBarAppearance.largeTitleTextAttributes = [.foregroundColor: largeTitleColor]
navBarAppearance.titleTextAttributes = [.foregroundColor: largeTitleColor]
navBarAppearance.backgroundColor = backgoundColor
navigationController?.navigationBar.standardAppearance = navBarAppearance
navigationController?.navigationBar.compactAppearance = navBarAppearance
navigationController?.navigationBar.scrollEdgeAppearance = navBarAppearance
navigationController?.navigationBar.prefersLargeTitles = preferredLargeTitle
navigationController?.navigationBar.isTranslucent = false
navigationController?.navigationBar.tintColor = tintColor
navigationItem.title = title
} else {
// Fallback on earlier versions
navigationController?.navigationBar.barTintColor = backgoundColor
navigationController?.navigationBar.tintColor = tintColor
navigationController?.navigationBar.isTranslucent = false
navigationItem.title = title
}
}}
How to use:
configureNavigationBar(largeTitleColor: .yourColor, backgoundColor: .yourColor, tintColor: .yourColor, title: "yuorTitle", preferredLargeTitle: true)
Set ViewController-based status bar...... to NO in info.plist if you want light Content
If you don't want largeTitles set it to false
for tranlsucent change navBarAppearance.configureWithOpaqueBackground() in:
navBarAppearance.configureWithDefaultBackground()
navigationController?.navigationBar.isTranslucent = true
in the call set background color to .clear
UPDATE: If you want to start with navigation controller and large Titles at first controller, don't forget to set launch controller in Scene Delegate like this:
guard let windowScene = (scene as? UIWindowScene) else { return }
window = UIWindow(windowScene: windowScene)
window?.makeKeyAndVisible()
let vC = UINavigationController(rootViewController: YourFirstViewController())
window?.rootViewController = vC
hope this help :)

You can probe create your custom navigation controller and called in your view controllers; is more easy, customize the native navigation controller is hard, but you can do it scouring subviews in the natives elements.
