Usage

1. Define your custom navigationbar style

//CustomNavigationBarStyle.swift
extension CommonNavigationBarStyle {
    static var red: CommonNavigationBarStyle {
        let style = CommonNavigationBarStyle()
        style.barBackgroundColor = .red
        style.tintColor = .white
        return style
    }
    ...
}

2. Create NavigationBarTransitionController

Create NavigationBarTransitionController instance and call navigationController(_:, willShow:, animated:) method

//BaseNavigationController.swift
import BDNavigationBarTransition

class BaseNavigationController: UINavigationController, UINavigationControllerDelegate {
    private let transitionController = NavigationBarTransitionController()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Set global default navigationbar style here
        transitionController.defaultNavigationBarStyle = CommonNavigationBarStyle.customDefault
        delegate = self
    }
    
    func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
        transitionController.navigationController(navigationController, willShow: viewController, animated: animated)
    }
    ......
}

3. Implement CustomNavigationBar protocol

// RedNaviBarViewController.swift
class RedNaviBarViewController:  UIViewController, CustomNavigationBar {
    var navigationBarStyle: NavigationBarStyleProtocol = CommonNavigationBarStyle.red
    ......
}

or

// RedNaviBarViewController.swift
extension RedNaviBarViewController: ViewControllerCustomNavigationBar {
    var navigationBarStyle: NavigationBarStyleProtocol {
        return CommonNavigationBarStyle.red
    }
}

More

You can create your custom NavigationBarStyle by conforms to NavigationBarStyleProtocol and implement refresh(_ navigationBar:, from:, to:) method to decide how to display navigationBar
