ios - UITabBarController动态

Question

我必须创建一个 UITabBarController。无论用户是否登录，项目都可能发生变化。是否可以动态更改ta栏项目？

有人有想法吗？

谢谢

可以设置

var items: [UITabBarItem]? { get set }

或者用动画设置它:

func setItems(_ items: [UITabBarItem]?, 
 animated: Bool)

代码片段:

let item1 =  UITabBarItem(
        title: "first",
        image: firstImage,
        tag: 1)

let item2 =  UITabBarItem(
        title: "second",
        image: secondImage,
        tag: 2)
yourTabBarVC.tabBar.items = [item1,item2]


let first = FirstViewController()
let second = SecondViewController()

yourTabBarVC.viewControllers = [first, second]
