ios - 如何仅启动具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，它启动了一个仅包含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"];

如何只显示有手机/电话号码的联系人？我已经翻遍了 Apple 文档以找到用于 @count 操作的 key (本例中为 emailAddresses)，但我找不到它。

Answer 1

像这样使用 ABPersonPhoneNumbersProperty:

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