Answer 1

在导航控制器中为嵌入式控制器设置 tabBarItem。

  fileprivate func appenedVC(for rootViewController: UIViewController, tabBarTitle: String, image: UIImage) -> UIViewController {
    rootViewController.tabBarItem = UITabBarItem(title: title, image: image, selectedImage: image)
    rootViewController.title = tabBarTitle
    let navController = UINavigationController(rootViewController: rootViewController)
    navController.navigationBar.prefersLargeTitles = true
    return navController
  }

Answer 2

把它放在你的视图控制器中 - viewDidLoad()

self.title = “title“
self.tabBarItem.image = UIImage(named: “tabImage“)
self.tabBarItem.selectedImage = UIImage(named: “tabSelected”)

您也可以通过情节提要来做到这一点。 Select 导航控制器中的选项卡栏项目，然后转到属性检查器并输入标题。
