ios - 使用 Contact.framework iOS 过滤和隐藏特定联系人

Question

我想filter out contact with only email address隐藏phone number only contacts.

到目前为止，我已经能够禁用phone number only contacts.

    let picker = CNContactPickerViewController()
    picker.predicateForEnablingContact = NSPredicate(format: "emailAddresses.@count > 0")
    picker.delegate = self

    self.present(picker, animated: true, completion: nil)
