而我得到这个

当我点击其显示的任何标签栏项目时

这是我在配置文件视图控制器中使用的代码

class ProfileViewController: UIViewController {
 override func viewDidLoad() {
        super.viewDidLoad()
        UIApplication.shared.statusBarStyle = .default

        self.tabBarController?.tabBar.isHidden = false
        UITabBar.appearance().tintColor = UIColor.init(patternImage: UIImage.init(named: "ic_home_tab_profile_sel.png")!)
        // Do any additional setup after loading the view.
    }
}

任何帮助都可以欣赏.先感谢您.

Answer 1

我建议使用ESTabBarControllerExample https://github.com/eggswift/ESTabBarController制作那种自定义TabbarController.First从github下载ESTabbarControllerExample.我们需要使用一些课堂信.让我解释一下如何逐步使用:

• 首先安装CocoaPods

  1打开终端和 cd ~ to your project directory

  2运行命令 - pod init

  3您的podfile应该与 - 一起使用pod "ESTabBarController-swift"并保存

  4并使用命令安装它 pod install

• 打开.xcworkspace扩展的项目文件

  1在项目中我们需要添加Content所有swift类和pop.framework

  2不要使用添加文件来添加pop.framework.您必须从Framework添加并添加其他.

  3在"内容"文件夹的所有文件中 import ESTabBarController_swift

• StoryBord的东西

  1添加导航控制器也可以ExampleNavigationController从EST演示的示例代码中添加.(您也可以添加自己的)但请确保将其导航类设置为自定义swift类.

• AppDelegate.swift的代码资料

您需要在侧面执行以下代码 didFinishLaunchingWithOptions

            let tabBarController = ESTabBarController()
            tabBarController.delegate = self
            tabBarController.title = "Irregularity"
            tabBarController.tabBar.shadowImage = UIImage(named: "transparent")
            tabBarController.tabBar.backgroundImage = UIImage(named: "background_dark")
            tabBarController.shouldHijackHandler = {
                tabbarController, viewController, index in
                if index == 2 {
                    return true
                }
                return false
            }
            tabBarController.didHijackHandler = {
                [weak tabBarController] tabbarController, viewController, index in

                DispatchQueue.main.asyncAfter(deadline: .now() + 0.2) {
                    let alertController = UIAlertController.init(title: nil, message: nil, preferredStyle: .actionSheet)
                    let takePhotoAction = UIAlertAction(title: "Take a photo", style: .default, handler: nil)
                    alertController.addAction(takePhotoAction)
                    let selectFromAlbumAction = UIAlertAction(title: "Select from album", style: .default, handler: nil)
                    alertController.addAction(selectFromAlbumAction)
                    let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
                    alertController.addAction(cancelAction)
                    tabBarController?.present(alertController, animated: true, completion: nil)
                }
            }

            let v1 = ExampleViewController()
            let v2 = ExampleViewController()
            let v3 = ExampleViewController()
            let v4 = ExampleViewController()
            let v5 = ExampleViewController()

            v1.tabBarItem = ESTabBarItem.init(ExampleIrregularityBasicContentView(), title: "Home", image: UIImage(named: "home"), selectedImage: UIImage(named: "home_1"))
            v2.tabBarItem = ESTabBarItem.init(ExampleIrregularityBasicContentView(), title: "Find", image: UIImage(named: "find"), selectedImage: UIImage(named: "find_1"))
            v3.tabBarItem = ESTabBarItem.init(ExampleIrregularityContentView(), title: nil, image: UIImage(named: "photo_verybig"), selectedImage: UIImage(named: "photo_verybig"))
            v4.tabBarItem = ESTabBarItem.init(ExampleIrregularityBasicContentView(), title: "Favor", image: UIImage(named: "favor"), selectedImage: UIImage(named: "favor_1"))
            v5.tabBarItem = ESTabBarItem.init(ExampleIrregularityBasicContentView(), title: "Me", image: UIImage(named: "me"), selectedImage: UIImage(named: "me_1"))

            tabBarController.viewControllers = [v1, v2, v3, v4, v5]

            let navigationController = ExampleNavigationController.init(rootViewController: tabBarController)
            tabBarController.title = "Example"


        self.window?.rootViewController = navigationController

        return true

为标签栏项添加图像以及要在资产中使用的其他图像.希望对你有所帮助.
