ios - 更改AppDelegate的根 View Controller 会导致UIViewControllerHierarchyInconsistency异常

在AppDelegate之外，我想更改它的rootViewController。换句话说，我想在窗口中放置一个新的导航控制器，然后将其推入该导航控制器中：

func JumpToPage(_ controller: UIViewController) {
        guard let rootController = AppDelegate.shared?.presentationViewController else {
            return
        }
        let navigationController = UINavigationController(rootViewController: rootController)
        navigationController.pushViewController(controller, animated: true)
        AppDelegate.shared?.window?.rootViewController = navigationController
    }
}

但是此功能导致应用程序崩溃并显示以下错误消息：

Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency',
    reason: 'adding a root view controller <MyExampleController> as a child of view controller:<UINavigationController>'

我应该如何解决？

最佳答案

从

let navigationController = UINavigationController(rootViewController: rootController)

至

let navigationController = UINavigationController(rootViewController: controller)

更新资料

func JumpToPage(_ controller: UIViewController) {
    guard let rootController = AppDelegate.shared?.presentationViewController else {
        return
    }
    let navigationController = UINavigationController(rootViewController: controller)
    AppDelegate.shared?.window?.rootViewController = navigationController
}
