Я пытался решить эту проблему некоторое время, поэтому вот мой вопрос:
Я хочу создать неизвестный контакт с заданным набором значений, как вы можете сказать:
fileprivate func showUnknownContactViewController() {
let aContact = CNMutableContact()
let newEmail = CNLabeledValue(label: CNLabelWork, value: email! as NSString)
aContact.emailAddresses.append(newEmail)
let workPhone = CNLabeledValue(label: CNLabelWork, value: CNPhoneNumber(stringValue : phone!))
aContact.phoneNumbers.append(workPhone)
let ucvc = CNContactViewController(forUnknownContact: aContact)
ucvc.delegate = self
ucvc.allowsEditing = true
ucvc.allowsActions = true
ucvc.alternateName = firstName! + " " + lastName!
ucvc.title = "Company"
ucvc.message = UserDefaults.standard.string(forKey: "company")!
ucvc.contactStore = self.store //needed for editing/adding contacts?
self.navigationController?.pushViewController(ucvc, animated: true)
}
Я также вызвал функцию делегата, которая, я не уверен, имеет какой-либо эффект:
func contactViewController(_ viewController: CNContactViewController, shouldPerformDefaultActionFor property: CNContactProperty) -> Bool {
return true
}
При нажатии на ucvc моя навигационная панель становится черной, а в этом уроке, которому я следовал, - нет. Примечание: я не использую табличное представление, я просто использовал функцию showUnknownContactViewController.

Я попытался изменить навигационный контроллер ucvc следующим образом:
ucvc.navigationController?.navigationBar.backgroundColor = UIColor(red: 0.0, green: 0.0, blue: 0.0, alpha: 1)
Я также пытался установить backgroundImage для пустого изображения:
ucvc.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
Что-то интересное, что я вижу, когда я загружаю ucvc, я получаю это из журнала консоли:
Доступ к файлу PassKit Shared Cache запрещен. Пожалуйста, проверьте исключения из песочницы и / или подайте радар.
Но все равно получается черный. Что я делаю не так и как бы мне помешать черной навигационной панели? Это выглядит так:

Просто дайте мне знать, если я публикую много кода, я думаю, что лучше слишком много, чем слишком мало:)
