How to get the selected contactProperty from CNContactPickerViewController - ios

Question

I'm currently able to get a contact from the contacts app, but the problem I'm facing that I need to be able to select the contact I want to import to my app , if the contact have more than 1 phone number, I always get the first number, here is the code I'm using:
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()
}
}
The problem with line:
contactProperty.contact.phoneNumbers.first
There are two options only for contactProperty.contact.phoneNumbers .first or .last
If there is something like .selected, it would solve the problem.

Answer 1

There is something called Main telephone number that you could use
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
}
Note that I changed the definition of numbers to be the array of phone numbers
let numbers = contactProperty.contact.phoneNumbers
Full code:
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()
}
}

Answer 2

I'm agree with solution of Joakim Danielson.
But there are one more solution to get specific phone number which is stored in mobile number like home, mobile, fax etc.
Get all numbers from contact and enumerate on every number and check labeled values. See following code.
let numbers = contact.phoneNumbers
numbers.forEach { (c) in
if let label = c.label {
let localizedLabel = CNLabeledValue<NSCopying & NSSecureCoding>.localizedString(forLabel: label)
print("\(localizedLabel)")
switch localizedLabel.lowercased() {
case "home":
let homeNumber = c.value
break
case "mobile":
let mobileNumber = c.value
break
default:
break
}
}
}

contactProperty.contacts is a back-reference to the CNContact the selected property lives in...
Each property is represented by an instance of CNContactProperty, which provides a tuple that can contain three or five values, depending on whether the property is a member of an array of labeled values.
CNContactProperty
So, you should use the property's Information vars directly:
For example, the phoneNumbers property is a member of an array of labeled values, so the CNContactProperty tuple contains the contact, key, value, identifier, and label.
CNContactProperty
