在iOS中,可以使用以下方法来实现控制的切换:
let tabBarController = UITabBarController()
tabBarController.viewControllers = [viewController1, viewController2, viewController3]
let navigationController = UINavigationController(rootViewController: viewController1)
navigationController.pushViewController(viewController2, animated: true)
navigationController.popViewController(animated: true)
present(viewController, animated: true, completion: nil)
dismiss(animated: true, completion: nil)
containerView.addSubview(viewController.view)
这些方法可以根据具体的需求和场景进行选择和组合使用来实现控制的切换。
