iOS ) UITabBarController 페이지 Programmatically 만들기 swift

 

1. viewdidLoad에 generateNavController 메서드 호출

override func viewDidLoad() {
        super.viewDidLoad()
        itembar_height = Int(view.frame.height * 0.1)
        view.backgroundColor = .white
        //블랙모드 방지
        overrideUserInterfaceStyle = .light
        //tabBar.barTintColor = .blue
        
        let nav = generateNavController(vc: ViewController(), title: "1", image: #imageLiteral(resourceName: "unselected_image"), image_selected: #imageLiteral(resourceName: "eletecd_image"))
        let nav2 = generateNavController(vc: ViewController(), title: "2", image: #imageLiteral(resourceName: "_nselected_image"), image_selected: #imageLiteral(resourceName: "seletecd_image"))
        //UINavigationBar.appearance().prefersLargeTitles = true
        
        self.tabBar.unselectedItemTintColor = .black
      
        
        viewControllers = [nav, nav2]
        
        // Do any additional setup after loading the view.
    }

2. 텝바에서 생성할 네비게이션 컨트롤러 메서드 

fileprivate func generateNavController(vc : UIViewController, title : String, image: UIImage, image_selected : UIImage) -> UINavigationController
    {
        //네비게이션 컨트롤러 생성
        let navController = UINavigationController(rootViewController: vc)
        
        ///텝바의 이미지 커스텀하기
        navController.tabBarItem.image = image
        navController.tabBarItem.selectedImage = image_selected
        
        // 이하 뒤로가기 버튼의 글자 커스텀하기
        let backItem = UIBarButtonItem()
        backItem.title = "뒤로"
        vc.navigationItem.backBarButtonItem = backItem
        
        // 넘어갈 페이지 상단 타이틀 설정
        vc.navigationItem.title = title 
        return navController
     }
