So rufen Sie alle Kontaktdatensätze in iOS 9 mit dem Contacts Framework ab
Der größte Teil des Adressbuch-Frameworks ist in iOS 9 veraltet. Im neuen Kontakt-Framework zeigt Dokumentation nur, wie Datensätze abgerufen werden, die mit NSPredicate übereinstimmen, aber was ist, wenn ich möchte alle die Aufzeichnung?
Beide anderen Antworten laden nur Kontakte aus dem Container mit dem defaultContainerIdentifier. In einem Szenario, in dem der Benutzer über mehr als einen Container verfügt (d. H. Ein Exchange- und ein iCloud-Konto, die beide zum Speichern von Kontakten verwendet werden), werden die Kontakte nur von dem Konto geladen, das als Standard konfiguriert ist. Daher würde es nicht laden alle Kontakte, wie vom Autor der Frage angefordert.
Sie möchten wahrscheinlich stattdessen alle Container abrufen und sie durchlaufen, um alle Kontakte aus jedem dieser Container zu extrahieren. Das folgende Code-Snippet ist ein Beispiel dafür, wie wir es in einer unserer Apps (in Swift) machen:
lazy var contacts: [CNContact] = {
let contactStore = CNContactStore()
let keysToFetch = [
CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName),
CNContactEmailAddressesKey,
CNContactPhoneNumbersKey,
CNContactImageDataAvailableKey,
CNContactThumbnailImageDataKey]
// Get all the containers
var allContainers: [CNContainer] = []
do {
allContainers = try contactStore.containersMatchingPredicate(nil)
} catch {
print("Error fetching containers")
}
var results: [CNContact] = []
// Iterate all containers and append their contacts to our results array
for container in allContainers {
let fetchPredicate = CNContact.predicateForContactsInContainerWithIdentifier(container.identifier)
do {
let containerResults = try contactStore.unifiedContactsMatchingPredicate(fetchPredicate, keysToFetch: keysToFetch)
results.appendContentsOf(containerResults)
} catch {
print("Error fetching results for container")
}
}
return results
}()
Ziel c:
//ios 9+
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
//keys with fetching properties
NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
NSString *containerId = store.defaultContainerIdentifier;
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
NSError *error;
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
if (error) {
NSLog(@"error fetching contacts %@", error);
} else {
for (CNContact *contact in cnContacts) {
// copy data to my custom Contacts class.
Contact *newContact = [[Contact alloc] init];
newContact.firstName = contact.givenName;
newContact.lastName = contact.familyName;
UIImage *image = [UIImage imageWithData:contact.imageData];
newContact.image = image;
for (CNLabeledValue *label in contact.phoneNumbers) {
NSString *phone = [label.value stringValue];
if ([phone length] > 0) {
[contact.phones addObject:phone];
}
}
}
}
}
}];
Um alle Kontakte zu erhalten, können Sie auch die enumerateContactsWithFetchRequest -Methode verwenden:
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
//keys with fetching properties
NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys];
NSError *error;
BOOL success = [store enumerateContactsWithFetchRequest:request error:&error usingBlock:^(CNContact * __nonnull contact, BOOL * __nonnull stop) {
if (error) {
NSLog(@"error fetching contacts %@", error);
} else {
// copy data to my custom Contact class.
Contact *newContact = [[Contact alloc] init];
newContact.firstName = contact.givenName;
newContact.lastName = contact.familyName;
// etc.
}
}];
}
}];
Wenn Sie Kontakte nach Namen filtern möchten , können Sie dies verwenden:
Objekt-C:
// keys from example above
NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:[CNContact predicateForContactsMatchingName:@"John Appleseed"] keysToFetch:keys error:&error];
Swift 3:
let store = CNContactStore()
let contacts = try store.unifiedContactsMatchingPredicate(CNContact.predicateForContactsMatchingName("Appleseed"), keysToFetch:[CNContactGivenNameKey, CNContactFamilyNameKey])
Die offizielle Dokumentation finden Sie hier: https://developer.Apple.com/reference/contacts
Verwenden Sie das Framework Swift und Contacts, um alle Kontakte abzurufen, einschließlich Name und Telefonnummer
import Contacts
let store = CNContactStore()
store.requestAccessForEntityType(.Contacts, completionHandler: {
granted, error in
guard granted else {
let alert = UIAlertController(title: "Can't access contact", message: "Please go to Settings -> MyApp to enable contact permission", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
self.presentViewController(alert, animated: true, completion: nil)
return
}
let keysToFetch = [CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName), CNContactPhoneNumbersKey]
let request = CNContactFetchRequest(keysToFetch: keysToFetch)
var cnContacts = [CNContact]()
do {
try store.enumerateContactsWithFetchRequest(request){
(contact, cursor) -> Void in
cnContacts.append(contact)
}
} catch let error {
NSLog("Fetch contact error: \(error)")
}
NSLog(">>>> Contact list:")
for contact in cnContacts {
let fullName = CNContactFormatter.stringFromContact(contact, style: .FullName) ?? "No Name"
NSLog("\(fullName): \(contact.phoneNumbers.description)")
}
})
Das Abrufen von Kontakten ist langsam Vorgang, daher sollten Sie den Haupt-UI-Thread nicht blockieren. Führe CNContactFetchRequest im Hintergrund-Thread aus. Deshalb habe ich den Code in CompletionHandler eingefügt. Es läuft auf einem Hintergrund-Thread.
Apple empfiehlt tatsächlich, "enumerateContactsWithFetchRequest of CNContactStore" zu verwenden, um alle Kontakte abzurufen und [~ # ~] nicht [~ # ~] unifiedContactsMatchingPredicate.
Unten ist der Arbeitscode für Obj-C.
CNContactStore *store = [[CNContactStore alloc] init];
//keys with fetching properties
NSArray *keys = @[CNContactGivenNameKey, CNContactPhoneNumbersKey];
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys];
NSError *error;
[store enumerateContactsWithFetchRequest:request error:&error usingBlock:^(CNContact * __nonnull contact, BOOL * __nonnull stop) {
// access it this way -> contact.givenName; etc
}];
Hier ist der Link, in dem Apple empfiehlt Aufzählungsfunktion: https://developer.Apple.com/reference/contacts/cncontactstore/1403266-unifiedcontactsmatchingpredicate?language=objc#discussion =
Wenn der Link abgelaufen ist, ist hier was Apple schrieb:
Wenn keine Übereinstimmungen gefunden werden, gibt diese Methode ein leeres Array zurück (oder null im Fehlerfall). Verwenden Sie nur die Prädikate aus den Prädikaten der CNContact-Klasse. Zusammengesetzte Prädikate werden von dieser Methode nicht unterstützt. Aufgrund der Vereinheitlichung haben die zurückgegebenen Kontakte möglicherweise andere Bezeichner als die von Ihnen angegebenen. Um alle Kontakte abzurufen , verwenden Sie
enumerateContactsWithFetchRequest:error:usingBlock:.
Für Swift 4
var results: [CNContact] = []
let fetchRequest = CNContactFetchRequest(keysToFetch: [CNContactGivenNameKey as CNKeyDescriptor, CNContactFamilyNameKey as CNKeyDescriptor, CNContactMiddleNameKey as CNKeyDescriptor, CNContactEmailAddressesKey as CNKeyDescriptor,CNContactPhoneNumbersKey as CNKeyDescriptor])
fetchRequest.sortOrder = CNContactSortOrder.userDefault
let store = CNContactStore()
do {
try store.enumerateContacts(with: fetchRequest, usingBlock: { (contact, stop) -> Void in
print(contact.phoneNumbers.first?.value ?? "no")
results.append(contact)
})
}
catch let error as NSError {
print(error.localizedDescription)
}
ältere Version für Swift var Ergebnisse enthält alle Kontakte
let contactStore = CNContactStore()
var results: [CNContact] = []
do {
try contactStore.enumerateContactsWithFetchRequest(CNContactFetchRequest(keysToFetch: [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactMiddleNameKey, CNContactEmailAddressesKey,CNContactPhoneNumbersKey])) {
(contact, cursor) -> Void in
results.append(contact)
}
}
catch{
print("Handle the error please")

@ Rocolitis Antwort in Swift! Seine Antwort ist laut Apples Dokumentation der richtigste Weg, dies zu tun.
let contactStore = CNContactStore()
let keys = [CNContactPhoneNumbersKey, CNContactFamilyNameKey, CNContactGivenNameKey, CNContactNicknameKey] as [CNKeyDescriptor]
let request = CNContactFetchRequest(keysToFetch: keys)
try? contactStore.enumerateContacts(with: request) { (contact, error) in
// Do something with contact
}
Sie sollten wahrscheinlich zuerst Ihren Zugang zu Ihren Kontakten überprüfen!
let authorization = CNContactStore.authorizationStatus(for: CNEntityType.contacts)
switch authorization {
case .authorized: break
case .denied: break
case .restricted: break
case .notDetermined: break
}
rufen Sie zuerst die Standard-Container-ID ab und verwenden Sie die mit dem Prädikat übereinstimmende Container-ID
let keysToFetch = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey]
let containerId = CNContactStore().defaultContainerIdentifier()
let predicate: NSPredicate = CNContact.predicateForContactsInContainerWithIdentifier(containerId)
let contacts = try CNContactStore().unifiedContactsMatchingPredicate(predicate, keysToFetch: keysToFetch)

Codys Antwort in Swift 3:

Dann in welcher Funktion auch immer Sie verwenden:
let store = CNContactStore()
store.requestAccess(for: .contacts, completionHandler: {
granted, error in
guard granted else {
let alert = UIAlertController(title: "Can't access contact", message: "Please go to Settings -> MyApp to enable contact permission", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alert, animated: true, completion: nil)
return
}
let keysToFetch = [CNContactFormatter.descriptorForRequiredKeys(for: .fullName), CNContactPhoneNumbersKey] as [Any]
let request = CNContactFetchRequest(keysToFetch: keysToFetch as! [CNKeyDescriptor])
var cnContacts = [CNContact]()
do {
try store.enumerateContacts(with: request){
(contact, cursor) -> Void in
cnContacts.append(contact)
}
} catch let error {
NSLog("Fetch contact error: \(error)")
}
print(">>>> Contact list:")
for contact in cnContacts {
let fullName = CNContactFormatter.string(from: contact, style: .fullName) ?? "No Name"
print("\(fullName): \(contact.phoneNumbers.description)")
}
})
Ich versuche diesen Code, es funktioniert gut. Ich kann alle Kontaktdetails mit diesem Code in Swift3 aktuellem Framework mit Kontakten abrufen:
let requestForContacts = CNContactFetchRequest(keysToFetch: [CNContactIdentifierKey as CNKeyDescriptor, CNContactFormatter.descriptorForRequiredKeys(for: CNContactFormatterStyle.fullName), CNContactPhoneNumbersKey as CNKeyDescriptor ,CNContactImageDataKey as CNKeyDescriptor,CNContactEmailAddressesKey as CNKeyDescriptor,CNContactBirthdayKey as CNKeyDescriptor])
do {
try self.store.enumerateContacts(with: requestForContacts) { contact, stop in
print("contact:\(contact)")
self.contacts.append(contact)
}
} catch {
print(error)
}
for contact in self.contacts {
print(contact)
let firstName = contact.givenName
nameArray.append(firstName)
print("first:\(firstName)")
let phoneNumber = (contact.phoneNumbers[0].value).value(forKey: "digits")
phoneNumberArray.append(phoneNumber as! String)
let emailAddress = contact.emailAddresses[0].value(forKey: "value")
emailAddressArray.append(emailAddress as! String)
}
Hier ist der Swift 3.0 Version von Floheis Antwort
lazy var contacts: [CNContact] = {
let contactStore = CNContactStore()
let keysToFetch = [
CNContactFormatter.descriptorForRequiredKeys(for: .fullName),
CNContactPostalAddressesKey,
CNContactEmailAddressesKey,
CNContactPhoneNumbersKey,
CNContactImageDataAvailableKey,

do {

}
var results: [CNContact] = []
// Iterate all containers and append their contacts to our results array
for container in allContainers {
let fetchPredicate = CNContact.predicateForContactsInContainer(withIdentifier: container.identifier)
do {
let containerResults = try contactStore.unifiedContacts(matching: fetchPredicate, keysToFetch: keysToFetch as! [CNKeyDescriptor])
results.append(contentsOf: containerResults)

Hoffe das hilft!

})
}
catch let error {
print(error.localizedDescription)
}
completion(results)
}else{
print("Error \(error?.localizedDescription ?? "")")
}
})
}
}
Verwendung:
fetchContacts(completion: {contacts in
contacts.forEach({print("Name: \($0.givenName), number: \($0.phoneNumbers.first?.value.stringValue ?? "nil")")})
Sie müssen zuerst die Nutzungsinformationen in info.plist beschreiben. Ich habe eine Überprüfung hinzugefügt, um festzustellen, ob der Benutzer den Zugriff auf Kontakte gewährt hat, und dann die Schlüssel definiert (die Werte, die abgerufen werden müssen). Wie in einer der vorherigen Antworten erwähnt, ist dies ein zeitaufwändiger Prozess. Deshalb habe ich DispatchQueue für die Hintergrundverarbeitung und Completion Handler für die Rückgabe des Kontaktarrays an den Aufrufer hinzugefügt.
Momentan ist ABAddressBookRef in iOS9 veraltet. Um alle Kontakte vom Telefon abzurufen, verwenden Sie dieses Framework und fügen Sie diese Funktion hinzu. Sie erhalten eine Reihe von Kontakten.
importieren Sie das Kontakt-Framework in einer solchen Klasse .h
#import <Contacts/Contacts.h>
fügen Sie dann diese Methode in der M-Datei hinzu

NSString *containerId = store.defaultContainerIdentifier;
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
NSError *error;
