本文详细介绍了使用Swift语言创建带有TabBar的iOS应用程序的过程。从创建项目到设置导航条，再到实现四个不同功能的视图控制器，每个步骤都清晰明了。通过继承UIViewController和UITabBarController，文章展示了如何构建并配置各个页面及其图标。

首先创建工程选择swift语言
AppDelegate
设置导航条

let Mian = MainViewController()
self.window?.rootViewController = Mian

创建继承于UIViewController的类分别为
OneViewController
TwoViewController
ThreeViewController
FourViewController
再创建一个继承于UITabBarController的类名为MainViewController
代码为:
(备注:名称/图片/点击后图片自行添加)

        self.title = "设置标题"
        self.navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(shuchu))
        
        
        let one = OneViewController()
        let oneNav = UINavigationController(rootViewController: one)
        oneNav.tabBarItem.title = ""
        oneNav.tabBarItem.image = UIImage(named: "")
        oneNav.tabBarItem.selectedImage = UIImage(named: "")
        
        let two = TwoViewController()
        let twoNav = UINavigationController(rootViewController: two)
        twoNav.tabBarItem.title = ""
        twoNav.tabBarItem.image = UIImage(named: "")
        twoNav.tabBarItem.selectedImage = UIImage(named: "")
        
        let three = ThreeViewController()
        let threeNav = UINavigationController(rootViewController: three)
        threeNav.tabBarItem.title = ""
        threeNav.tabBarItem.image = UIImage(named: "")
        threeNav.tabBarItem.selectedImage = UIImage(named: "")
        
        let four = FourViewController()
        let fourNav = UINavigationController(rootViewController: four)
        threeNav.tabBarItem.title = ""
        threeNav.tabBarItem.image = UIImage(named: "")
        threeNav.tabBarItem.selectedImage = UIImage(named: "")
       
         
         self.viewControllers = [oneNav,twoNav,threeNav,fourNav]
        
    }
    @objc func shuchu(){
        print("%p")
    }
