UINavigationBarDecorator

Using with factory

class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        UINavigationBarDecorator.isAllowsSwizzleLifeCycleOfViewController = true
        UINavigationBarDecorator.factory = SampleNavigationBarDecoratorFactory()
        return true
    }
}

struct SampleNavigationBarDecoratorFactory: UINavigationBarDecoratorFactory {
    func create(of vc: UIViewController) -> UINavigationBarDecorator? {
        switch vc {
        case is RootViewController:
            return .init(standard: .orange, compact: .orange, scrollEdge: .orange)
        case is SecondViewController:
            return .init(standard: .purple, compact: .purple, scrollEdge: .purple)
        default:
            return nil
        }
    }
}

extension CompatibleNavigationBarAppearance {
    static var purple: CompatibleNavigationBarAppearance {
        let appearance = CompatibleNavigationBarAppearance()
        appearance.backgroundColor = .purple
        appearance.tintColor = .white
        appearance.largeTitleTextAttributes = [
            .foregroundColor: UIColor.white
        ]
        appearance.titleTextAttributes = [
            .foregroundColor: UIColor.white,
            .font : UIFont.systemFont(ofSize: 17, weight: .semibold)
        ]
        return appearance
    }
    static var orange: CompatibleNavigationBarAppearance {
        let appearance = CompatibleNavigationBarAppearance()
        appearance.backgroundColor = .orange
        appearance.tintColor = .black
        appearance.largeTitleTextAttributes = [
            .foregroundColor: UIColor.black
        ]
        appearance.titleTextAttributes = [
            .foregroundColor: UIColor.black,
            .font : UIFont.systemFont(ofSize: 17, weight: .semibold)
        ]
        return appearance
    }
}

Using without factory

• set the decorator directly on the view controller

final class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        navigationBarDecorator = .init(standard: .orange, compact: .orange, scrollEdge: .orange)
    }
}

Apply decorator manually

class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        UINavigationBarDecorator.isAllowsSwizzleLifeCycleOfViewController = false
        UINavigationBarDecorator.factory = SampleNavigationBarDecoratorFactory()
        return true
    }
}

final class SampleNavigationController: UINavigationController {
    override var childForStatusBarStyle: UIViewController? {
        topViewController
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        delegate = self
    }
}

extension SampleNavigationController: UINavigationControllerDelegate {
    func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
        viewController.navigationBarDecorator?.decorate(to: viewController)
    }
    func navigationController(_ navigationController: UINavigationController, didShow viewController: UIViewController, animated: Bool) {
        viewController.navigationBarDecorator?.decorate(to: viewController, by: viewController.view.frame.size)
    }
}
