Question

此代码折叠了我的所有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CNContactViewController(forNewContact

似乎没问题

这是苹果虫吗？

你应该推 CNContactViewController 而不是现在。我建议你观看WWDC 2015关于这个问题的演讲。
