Question

我有一个应用程序，其中包含带有三个页面的标签栏控制器，其中我的标签栏控制器是初始视图控制器。我需要为我的三个页面创建一个自定义通用视图作为导航栏。我不需要从头开始创建导航栏。

首先使用navigationController创建一个类导入UIKit

    class CustomNavigationController: UIViewController {


    override func viewDidLoad() {
        super .viewDidLoad()
        addNavigationButton()
    }

    func addNavigationButton() {
 //      here you add custom nevigation
        let backButton = UIBarButtonItem(image: UIImage(named: "back"), style: .plain, target: self, action: #selector(backButtonAction))
        backButton.tintColor = .gray
        self.navigationItem.leftBarButtonItems = [backButton]
        let doneButton = UIBarButtonItem(title:"Done", style: .plain, target: self, action: #selector(doneButtonAction))
        navigationItem.rightBarButtonItem = doneButton
        //navigationItem.rightBarButtonItem = editButtonItem
//      self.title = "Select Timezone"
        UINavigationBar.appearance().titleTextAttributes = [NSAttributedStringKey.foregroundColor : #colorLiteral(red: 0, green: 0.4156862745, blue: 0.5529411765, alpha: 1)]
    }
    @objc func backButtonAction() {
        // as per requrement you want to use pop / dismisss


      self.dismiss(animated: true, completion: nil)
    }
        @objc func doneButtonAction() {
          // as per requrement you want to use pop / dismisss

            self.dismiss(animated: true, completion: nil)
        }

    }

并像这样使用这三个viewcontroller

import UIKit

class ViewController: CustomNavigationController {

  override func viewDidLoad() {
        super.viewDidLoad()
  }
}

如何为选项卡式页面创建自定义通用导航栏？
