Objectif c

#import <Contacts/Contacts.h>

Vérification de l'accessibilité

Rapide

switch CNContactStore.authorizationStatusForEntityType(CNEntityType.Contacts){
case .Authorized: //access contacts
case .Denied, .NotDetermined: //request permission
default: break
}

Objectif c

switch ([CNContactStore authorizationStatusForEntityType:CNEntityType.Contacts]){
case CNAuthorizationStatus.Authorized:
    //access contacts
    break;
case CNAuthorizationStatus.Denied:
    //request permission
    break;
case CNAuthorizationStatus.NotDetermined:
    //request permission
    break;
}

Demande de permission

Rapide

var contactStore = CKContactStore()
contactStore.requestAccessForEntityType(CKEntityType.Contacts, completionHandler: { (ok, _) -> Void in
    if access{
        //access contacts
    }
}

Accéder aux contacts

Appliquer un filtre

Pour accéder aux contacts, nous devons appliquer un filtre de type NSPredicate à notre variable contactStore que nous avons définie dans l'exemple Authorizing Contact Access. Par exemple, ici, nous voulons trier les contacts avec un nom correspondant au nôtre:

Rapide

let predicate = CNContact.predicateForContactsMatchingName("Some Name")

Objectif c

NSPredicate *predicate = [CNContact predicateForContactsMatchingName:@"Some Name"];

Spécifier les clés à récupérer

Ici, nous voulons récupérer le prénom, le nom et l'image de profil du contact:

Rapide

let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactImageDataKey]

Récupérer des contacts

Rapide

do {
    let contacts = try contactStore.unifiedContactsMatchingPredicate(predicate, keysToFetch: keys)
} catch let error as NSError {
    //...
}

Accéder aux coordonnées

Rapide

print(contacts[0].givenName)
print(contacts[1].familyName)
let image = contacts[2].imageData

Ajouter un contact

Rapide

import Contacts
 
// Creating a mutable object to add to the contact
let contact = CNMutableContact()
 
contact.imageData = NSData() // The profile picture as a NSData object
 
contact.givenName = "John"
contact.familyName = "Appleseed"
 
let homeEmail = CNLabeledValue(label:CNLabelHome, value:"[email protected]")
let workEmail = CNLabeledValue(label:CNLabelWork, value:"[email protected]")
contact.emailAddresses = [homeEmail, workEmail]
 
contact.phoneNumbers = [CNLabeledValue(
    label:CNLabelPhoneNumberiPhone,
    value:CNPhoneNumber(stringValue:"(408) 555-0126"))]
 
let homeAddress = CNMutablePostalAddress()
homeAddress.street = "1 Infinite Loop"
homeAddress.city = "Cupertino"
homeAddress.state = "CA"
homeAddress.postalCode = "95014"
contact.postalAddresses = [CNLabeledValue(label:CNLabelHome, value:homeAddress)]
 
let birthday = NSDateComponents()
birthday.day = 1
birthday.month = 4
birthday.year = 1988  // You can omit the year value for a yearless birthday
contact.birthday = birthday
 
// Saving the newly created contact
let store = CNContactStore()
let saveRequest = CNSaveRequest()
saveRequest.addContact(contact, toContainerWithIdentifier:nil)
try! store.executeSaveRequest(saveRequest)
