ios - 如何显示所有页面导航栏按钮

Question

我正在使用电子商务应用程序，我想显示所有页面篮子按钮..让用户点击任何页面，用户可以查看所有添加的产品列表，然后她可以从那里查看..

我的导航栏以编程方式制作:

  let viewController = DishViewController()
  viewController.shopCategory = shopCategory
  let navigationController = UINavigationController.init(rootViewController: viewController)

  self.present(navigationController, animated: true, completion: nil) 

目前我正在做我的每页 viewDidload() 显示篮子:

   func setupNavigationBar(){

        // back button without title
        self.navigationController?.navigationBar.topItem?.title = ""

        //set titile
        self.navigationItem.title = "Your Order"

        let rightButton = UIBarButtonItem(image: #imageLiteral(resourceName: "busket"), style: .plain, target: nil, action: nil)

        //show the Edit button item
        self.navigationItem.rightBarButtonItem = rightButton


    }

Answer 1

您可以为 UIViewController 创建一个扩展 并实现它们的功能。

extension UIViewController {
   func setupNavigationBar(title: String) {
        // back button without title
        self.navigationController?.navigationBar.topItem?.title = ""

        //set titile
        self.navigationItem.title = title

        let rightButton = UIBarButtonItem(image: #imageLiteral(resourceName: "busket"), style: .plain, target: nil, action: nil)

        //show the Edit button item
        self.navigationItem.rightBarButtonItem = rightButton
   }
}

并在您的 ViewControllers 的 ViewDidLoad 方法中简单地调用

setupNavigationBar(title: "Your Order")

希望这能解决您的问题。
