避免CNContactPickerViewController显示电子邮件 [英] avoid CNContactPickerViewController to show emails

问题描述

我使用以下代码在应用程序中显示联系人列表：

I use below code to show contact list in my application:

    self.contactPicker = [[CNContactPickerViewController alloc] init];
    self.contactPicker.delegate = self;
    self.contactPicker.predicateForSelectionOfContact =
    [NSPredicate predicateWithFormat:@"TRUEPREDICATE"];

    [viewController presentViewController:self.contactPicker
                                 animated:YES
                               completion:nil
     ];

该页面显示所有联系人，包括电子邮件。我只想显示数字（不显示电子邮件）， NSPredicate 或 CNContactPickerViewController 本身是否有任何选项，仅显示数字？

The page shows all contacts including emails . I want to only show numbers (and no emails) is there any options on the NSPredicate or CNContactPickerViewController itself to show only numbers?

我还使用过：

        self.contactPicker.displayedPropertyKeys = @[@"phoneNumber"];

但是它也不起作用。

推荐答案

displayedPropertyKeys 使用此属性控制应显示所有字段的内容。

displayedPropertyKeys use this property to control what all fields should be visible.

Swift 5.2示例

Swift 5.2 example

let contactViewController = CNContactPickerViewController()
contactViewController.displayedPropertyKeys = [CNContactPhoneNumbersKey]

// ... add delegate, present it, etc.
