import UIKit

class MainTabBarController: UITabBarController {
    
}

import UIKit

class MainTabBarController: UITabBarController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建并配置需要呈现的各个ViewController
        let homeViewController = HomeViewController()
        let profileViewController = ProfileViewController()
        
        // 分别设置每个ViewController的标题和图标
        homeViewController.title = "首页"
        homeViewController.tabBarItem.image = UIImage(named: "home")
        
        profileViewController.title = "个人资料"
        profileViewController.tabBarItem.image = UIImage(named: "profile")
        
        // 将创建的ViewController添加到TabBarController的viewControllers数组中
        viewControllers = [homeViewController, profileViewController]
    }
