如何更改 CNContactPickerViewController 导航栏的颜色？

Question

我想更改 CNContactPickerViewController 上显示的导航栏的颜色。

我已经尝试了下面的代码，但是它不起作用。

let contactPicker = CNContactPickerViewController()
//  let searchController = UISearchController()
contactPicker.delegate = self
contactPicker.modalPresentationStyle = .fullScreen
//        UISearchBar.appearance().text = "SEARCH".localized
//        contactPicker.navigationController?.isNavigationBarHidden = true
UINavigationBar.appearance().isTranslucent = false
UINavigationBar.appearance().barTintColor = .white
contactPicker.displayedPropertyKeys =
[CNContactPhoneNumbersKey, CNContactEmailAddressesKey]
contactPicker.predicateForEnablingContact = NSPredicate(format: "emailAddresses.@count > 0 || phoneNumbers.@count > 0")

present(contactPicker, animated: true)

Answer 1

您可以通过以下方式更改导航栏颜色：

UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().backgroundColor = .blue

这将更改整个应用程序的颜色，因此您可以在显示控制器之前更改颜色，并在控制器关闭时将其更改回原始颜色

Answer 2

如果您想更改 navigationBar 中文本的颜色，只需将这些行添加到 willConnectTo 方法中 SceneDelegate 文件:

 UINavigationBar.appearance().isTranslucent            = false
 UINavigationBar.appearance().barTintColor             = .orange
 UINavigationBar.appearance().tintColor                = .yellow
 UINavigationBar.appearance().titleTextAttributes      = [NSAttributedString.Key.foregroundColor: UIColor.purple]
 UINavigationBar.appearance().largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.purple]
