How to get a CNContact phone number(s) as string in Swift?
提问by Baylor Mitchell
I am attempting to retrieve the names and phone number(s) of all contacts and put them into arrays with Swift in iOS. I have made it this far:
我正在尝试检索所有联系人的姓名和电话号码，并在 iOS 中使用 Swift 将它们放入数组中。我已经做到了这一点：
func findContacts() -> [CNContact] {
marrContactsNumber.removeAllObjects()
marrContactsName.removeAllObjects()
let store = CNContactStore()
let keysToFetch = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey]
let fetchRequest = CNContactFetchRequest(keysToFetch: keysToFetch)
var contacts = [CNContact]()
do {
try store.enumerateContactsWithFetchRequest(fetchRequest, usingBlock: { (let contact, let stop) -> Void in
contacts.append(contact)
self.marrContactsName.addObject(contact.givenName + " " + contact.familyName)
self.marrContactsNumber.addObject(contact.phoneNumbers)
print(contact.phoneNumbers)
}
catch let error as NSError {
print(error.localizedDescription)
}
print(marrContactsName.count)
print(marrContactsNumber.count)
return contacts
}
Once completed, marrContactsNamecontains an array of all my contacts' names exactly as expected. i.e. "John Doe". However, marrContactsNumberreturns an array of values like
完成后，marrContactsName完全按照预期包含我所有联系人姓名的数组。即“约翰·多伊”。但是，marrContactsNumber返回一个值数组，如
[<CNLabeledValue: 0x158a19950: identifier=F831DC7E-5896-420F-AE46-489F6C14DA6E,
label=_$!<Work>!$_, value=<CNPhoneNumber: 0x158a19640: countryCode=us, digits=6751420000>>,
<CNLabeledValue: 0x158a19a80: identifier=ECD66568-C6DD-441D-9448-BDEDDE9A68E1,
label=_$!<Work>!$_, value=<CNPhoneNumber: 0x158a199b0: countryCode=us, digits=5342766455>>]
I would like to know how to retrieve JUST the phone number(s) as a string value(s) i.e. "XXXXXXXXXX". Basically, how to call for the digit(s) value. Thanks!
我想知道如何仅检索电话号码作为字符串值，即“XXXXXXXXXX”。基本上，如何调用数字值。谢谢！

I found the solution: (contact.phoneNumbers[0].value as! CNPhoneNumber).valueForKey("digits") as! String
我找到了解决方案： (contact.phoneNumbers[0].value as! CNPhoneNumber).valueForKey("digits") as! String

you can get contact.phoneNumbersfrom CNLabeledValue:
你可以contact.phoneNumbers从CNLabeledValue得到：
for phoneNumber in contact.phoneNumbers {
if let number = phoneNumber.value as? CNPhoneNumber,
let label = phoneNumber.label {
let localizedLabel = CNLabeledValue.localizedStringForLabel(label)
print("\(localizedLabel) \(number.stringValue)")
}
}

/* Get only first mobile number */
let MobNumVar = (contact.phoneNumbers[0].value as! CNPhoneNumber).valueForKey("digits") as! String
print(MobNumVar)
/* Get all mobile number */
for ContctNumVar: CNLabeledValue in contact.phoneNumbers
{
let MobNumVar = (ContctNumVar.value as! CNPhoneNumber).valueForKey("digits") as? String
print(MobNumVar!)
}
/* Get mobile number with mobile country code */
for ContctNumVar: CNLabeledValue in contact.phoneNumbers
{
let FulMobNumVar = ContctNumVar.value as! CNPhoneNumber
let MccNamVar = FulMobNumVar.valueForKey("countryCode") as? String
let MobNumVar = FulMobNumVar.valueForKey("digits") as? String
print(MccNamVar!)
print(MobNumVar!)
}

Here is how you do it in swift 4
这是你如何在 swift 4 中做到的
func contactPicker(_ picker: CNContactPickerViewController, didSelect contactProperty: CNContactProperty) {
if let phoneNo = contactProperty.value as? CNPhoneNumber{
txtPhone.text = phoneNo.stringValue
}else{
txtPhone.text=""
}
}

Here's a Swift 5 solution.
这是一个 Swift 5 解决方案。
import Contacts
func sendMessageTo(_ contact: CNContact) {
let validTypes = [
CNLabelPhoneNumberiPhone,
CNLabelPhoneNumberMobile,
CNLabelPhoneNumberMain
]
let numbers = contact.phoneNumbers.compactMap { phoneNumber -> String? in
guard let label = phoneNumber.label, validTypes.contains(label) else { return nil }
return phoneNumber.value.stringValue
}
guard !numbers.isEmpty else { return }
// process/use your numbers for this contact here
DispatchQueue.main.async {
self.sendSMSText(numbers)
}
}
You can find available values for the validTypesarray in the CNPhoneNumber header file.
您可以validTypes在 CNPhoneNumber 头文件中找到数组的可用值。
They are:
他们是：
CNLabelPhoneNumberiPhone
CNLabelPhoneNumberMobile
CNLabelPhoneNumberMain
CNLabelPhoneNumberHomeFax
CNLabelPhoneNumberWorkFax
CNLabelPhoneNumberOtherFax
CNLabelPhoneNumberPager

Keeping things simple:
保持简单：
let phoneNumbers: [String] = contact.phoneNumbers.compactMap { (phoneNumber: CNLabeledValue) in
guard let number = phoneNumber.value.value(forKey: "digits") as? String else { return nil }
return number
}

for Swift 5+
对于斯威夫特5+
func removeSpecialCharactersFromContactNumberOfUser(_ contactNo : String) -> String? {
let digits = CharacterSet(charactersIn: "0123456789").inverted
let modifiedContactNo = contactNo.components(separatedBy: digits).joined(separator: "")
if modifiedContactNo.count > 9 {
return modifiedContactNo
} else {
return nil
}
}
var number = phone.value.stringValue
number = number.starts(with: "+91") ? number.replacingOccurrences(of: "+91", with: "") : number
if let formattedNumber = removeSpecialCharactersFromContactNumberOfUser(number) {
//use this formattedNumber
}
This is to remove +91 from your phone number and it's working fine.
这是从您的电话号码中删除 +91 并且它工作正常。

The definition of a CNLabeledValue:
CNLabeledValue的定义：
The CNLabeledValue class is a thread-safe class that defines an immutable value object that combines a contact property value with a label. For example, a contact phone number could have a label of Home, Work, iPhone, etc.
CNLabeledValue 类是一个线程安全类，它定义了一个不可变值对象，该对象将联系人属性值与标签相结合。例如，联系电话号码可能带有“家庭”、“工作”、“iPhone”等标签。
CNContact.phoneNumbers is an array of CNLabeledValues and each CNLabeledValue has a label and a value.
CNContact.phoneNumbers 是一个 CNLabeledValues 数组，每个 CNLabeledValue 都有一个标签和一个值。
To print the phoneNumbers corresponding to a CNContact you can try:
要打印与 CNContact 对应的电话号码，您可以尝试：
for phoneNumber in contact.phoneNumbers {
print("The \(phoneNumber.label) number of \(contact.givenName) is: \(phoneNumber.value)")
}

Swift 3"_$!<Mobile>!$_"This item is written to create difference as well as putting a piece of opportunity to rely on various options.
Swift 3"_$!<Mobile>!$_"编写此项目是为了创造差异并提供依赖各种选项的机会。
for con in contacts
{
for num in con.phoneNumbers
{
if num.label == "_$!<Mobile>!$_" //Please Don't Change this!
{
self.contactNames.append(con.givenName)
self.contactNums.append(num.value.stringValue)
break
}
else
{
continue
}
}
}
Here we have num.value.stringValue
这里我们有 num.value.stringValue
