Swift 3D Touch打开TabBarController而不是RootViewController

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // 创建TabBarController实例
    let tabBarController = UITabBarController()
    
    // 设置TabBarController的视图控制器数组
    tabBarController.viewControllers = [ViewController1(), ViewController2(), ViewController3()]
    
    // 将TabBarController设置为根视图控制器
    window?.rootViewController = tabBarController
    
    return true
}

override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
    super.traitCollectionDidChange(previousTraitCollection)
    
    if traitCollection.forceTouchCapability == .available {
        // 设备支持3D Touch
        registerForPreviewing(with: self, sourceView: view)
    } else {
        // 设备不支持3D Touch
        // 处理其他逻辑
    }
}

extension ViewController: UIViewControllerPreviewingDelegate {
    func previewingContext(_ previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
        // 根据点击位置获取对应的视图控制器
        guard let tabBarController = tabBarController, let tabBarView = tabBarController.tabBar else {
            return nil
        }
        
        let tabBarFrame = tabBarView.convert(tabBarView.bounds, to: view)
        if tabBarFrame.contains(location) {
            // 点击位置在TabBar上
            // 返回TabBarController
            return tabBarController
        } else {
            // 点击位置在其他地方
            // 返回其他视图控制器
            return OtherViewController()
        }
    }
    
    func previewingContext(_ previewingContext: UIViewControllerPreviewing, commit viewControllerToCommit: UIViewController) {
        // 在这里进行视图控制器的跳转
        show(viewControllerToCommit, sender: self)
    }
}
