swift - 联系人有多个邮件时的 CNContactPickerViewController

Question

我正在使用 CNContactPickerViewController 让用户选择他/她的联系人之一的电子邮件

let contactPicker = CNContactPickerViewController()
contactPicker.delegate = self
contactPicker.predicateForSelectionOfContact = NSPredicate(format: "emailAddresses.@count > 0")
contactPicker.displayedPropertyKeys = [CNContactNicknameKey, CNContactEmailAddressesKey]

当联系人只有一封邮件时，一切顺利

func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {

    if let _mail = contact.emailAddresses.first?.value as String? {
        self.personWasSelected(with: _mail)
    }
}

但有时其中一个联系人有不止一封邮件，我如何让用户选择其中一封？

Answer 1

好的，通过试错找到了解决方案......

我同时实现了:

func contactPicker(_ picker: CNContactPickerViewController, didSelect contactProperty: CNContactProperty) {
    if let _mail = contactProperty.value as? String {
        self.personWasSelected(with: _mail)
    }
}

func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {

    if let _mail = contact.emailAddresses.first?.value as String? {
        self.personWasSelected(with: _mail)
    }
}

但是只有第一个应该已经实现了
