ios - 如何从 CNContactPickerViewController 获取选定的 contactProperty

Question

我目前可以从联系人应用程序获取联系人，但我面临的问题是，如果联系人有超过 1 部手机，我需要能够选择要导入到我的应用程序的联系人数字，我总是得到第一个数字，这是我正在使用的代码:

func contactPicker(_ picker: CNContactPickerViewController, didSelect contactProperty: CNContactProperty) {

    let numbers     = contactProperty.contact.phoneNumbers.first
    let firstName   = contactProperty.contact.givenName
    let lastName    = contactProperty.contact.familyName
    let phoneNumber = (numbers?.value)?.stringValue ?? ""

    /// Duplicate phone numbers will not be saved
    if phoneNumbers.contains(phoneNumber) {
        return
    }
    /// Saving selected contact in Core Data
    CoreDataManager.sharedInstance.savePhoneNumberInCoreData(FirstName: firstName, LastName: lastName, PhoneNumber: phoneNumber)

    DispatchQueue.main.async { [weak self] in
        self?.tableView.reloadData()
    }
}

线路问题:

contactProperty.contact.phoneNumbers.first

有两个选项仅适用于 contactProperty.contact.phoneNumbers .first 或 .last

如果有像.selected之类的东西，就可以解决问题。

Answer 1

您可以使用一个名为“主要电话号码”的东西

var phoneNumber: String?

if let mainNumber = numbers.first(where: { $0.label == CNLabelPhoneNumberMain }) {
    phoneNumber = mainNumber.value.stringValue
} else {
    phoneNumber = numbers.first?.value.stringValue //or some other default value
}

请注意，我将 numbers 的定义更改为电话号码数组

let numbers = contactProperty.contact.phoneNumbers

完整代码:

func contactPicker(_ picker: CNContactPickerViewController, didSelect contactProperty: CNContactProperty) {

    let numbers = contactProperty.contact.phoneNumbers    
    var phoneNumber: String?

    if let mainNumber = numbers.first(where: { $0.label == CNLabelPhoneNumberMain }) {
        phoneNumber = mainNumber.value.stringValue
    } else {
        phoneNumber = numbers.first?.value.stringValue //or some other default value
    }

    if phoneNumber == nil || phoneNumbers.contains(phoneNumber) {
        return
    }

    let firstName = contactProperty.contact.givenName
    let lastName = contactProperty.contact.familyName   

    CoreDataManager.sharedInstance.savePhoneNumberInCoreData(FirstName: firstName, LastName: lastName, PhoneNumber: phoneNumber)

    DispatchQueue.main.async { [weak self] in
        self?.tableView.reloadData()
    }
}
