此代码折叠我的所有uiviewcontroller层次结构

func openVCard(for cnContact: CNContact) {
        let contactViewController = CNContactViewController(forUnknownContact: cnContact)
        contactViewController.contactStore = CNContactStore()
        contactViewController.delegate = self

        let navigationController = UINavigationController(rootViewController: contactViewController)
        let doneButton = UIBarButtonItem(title: "Close", style: .done, target: nil, action: nil)
        let flexibleSpaceButton = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
        contactViewController.setToolbarItems([flexibleSpaceButton, doneButton, flexibleSpaceButton], animated: false)

        navigationController.isToolbarHidden = false
        contactViewController.edgesForExtendedLayout = []

        present(viewController: navigationController, animated: true, completion: nil)
    }

但似乎可以 CNContactViewController(forNewContact

是苹果虫吗?
