您好!关于这个问题,我们可以从以下几个方面进行考虑:
UITabBarItem
的属性。您可以在viewDidLoad
方法中添加以下代码来设置UITabBarItem
的标题:self.tabBarItem.title = "标题"
UITabBarItem
的标题,但是仍然不能正常显示,那么可能是因为您的UITabBarController
没有正确地设置。您可以在AppDelegate.swift
文件中设置UITabBarController
:func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
let tabBarController = UITabBarController()
let firstViewController = FirstViewController()
let secondViewController = SecondViewController()
firstViewController.tabBarItem.title = "第一个"
secondViewController.tabBarItem.title = "第二个"
tabBarController.viewControllers = [firstViewController, secondViewController]
self.window?.rootViewController = tabBarController
self.window?.makeKeyAndVisible()
return true
}

firstViewController.tabBarItem.title = "第一个"
