ios - 如何启动仅包含移动电话号码的联系人的ABPeoplePickerNavigationController？

苹果提供了一个名为PeoplePicker的示例项目，该项目仅启动具有电子邮件地址的联系人的ABPeoplePickerNavigationController:

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"];

如何仅显示具有手机/电话号码的联系人？我已经在Apple文档中进行了挖掘，以查找用于@count操作的密钥(在此示例中为emailAddresses)，但是我找不到它。

最佳答案

像这样使用ABPersonPhoneNumbersProperty:

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