如何启动只有手机号码的联系人的ABPeoplePickerNavigationController？

Question

Apple提供了一个名为PeoplePicker的示例项目，该项目启动ABPeoplePickerNavigationController只有电子邮件地址的联系人：

ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;

// The people picker will only display the person's name, image and email properties in ABPersonViewController.
picker.displayedProperties = @[@(kABPersonEmailProperty)];

// The people picker will enable selection of persons that have at least one email address.
picker.predicateForEnablingPerson = [NSPredicate predicateWithFormat:@"emailAddresses.@count > 0"];

如何仅显示包含手机/电话号码的联系人？我已经挖掘了Apple文档以找到用于@count操作的密钥（在此示例中为emailAddresses），但我找不到它。

像这样使用ABPersonPhoneNumbersProperty：

[NSPredicate predicateWithFormat:@"%K.@count > 0", ABPersonPhoneNumbersProperty];
