Solicitar acceso a contactos mediante programación

Desde que actualicé a iOS 6, noté que mi código para agregar un contacto a la libreta de direcciones del iPhone ya no funciona. Creo que este es un problema relacionado con los permisos, ya que Apple ahora requiere el permiso del usuario antes de acceder a los contactos (solucionando este problema).

Esperaba que la aplicación pidiera automáticamente permiso para acceder a los contactos, como en la captura de pantalla a continuación, pero no lo hace. Intentar agregar el contacto simplemente falla con ABAddressBookErrorDomain error 1.

¿Necesito iniciar mediante programación el diálogo de solicitud de acceso a contactos? ¿Cómo se hace eso?

Según esta documentación en el sitio de Apple (desplácese hacia abajo hasta Privacidad en el medio de la página), se debe otorgar acceso a la libreta de direcciones antes de que se pueda acceder mediante programación. Esto es lo que terminé haciendo.

  #import <AddressBookUI/AddressBookUI.h>

  // Request authorization to Address Book
  ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);

  if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
      if (granted) {
          // First time access has been granted, add the contact
          [self _addContactToAddressBook];
      } else {
          // User denied access
          // Display an alert telling user the contact could not be added
      }
    });
  }
  else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
    // The user has previously given access, add the contact
    [self _addContactToAddressBook];
  }
  else {
    // The user has previously denied access
    // Send an alert telling user to change privacy setting in settings app
  }

Actualización para iOS 9 y posterior:

Desde el sitio web de Apple:

Importante

El marco de la interfaz de usuario de la libreta de direcciones está obsoleto en iOS 9. En su lugar, use las API definidas en el marco de la interfaz de usuario de contactos. Para obtener más información, consulte ContactosUI

¡Ese fue el truco perfecto para mí!

En iOS6, Apple introduce un nuevo control de privacidad, el usuario puede controlar el acceso al contacto y al calendario de cada aplicación. Entonces, en el lado del código, debe agregar alguna forma de solicitar el permiso. En iOS5 o antes, siempre podemos llamar

ABAddressBookRef addressBook = ABAddressBookCreate();

para obtener la libreta de direcciones sin ningún problema, pero en iOS6, si no tiene permiso, esta llamada solo devolverá un puntero vacío. Es por eso que necesitamos cambiar el método para obtener ABAddressBookRef.

__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
    dispatch_semaphore_t sema = dispatch_semaphore_create(0);
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
        accessGranted = granted;
        dispatch_semaphore_signal(sema);
    });
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
    dispatch_release(sema);   
}
else { // we're on iOS 5 or older
    accessGranted = YES;
}

if (accessGranted) {
    // Do whatever you want here.
}

En el código, el semáforo se usa para bloquear hasta la respuesta, mientras que ABAddressBookRequestAccessWithCompletion solicitará permiso si la aplicación no lo solicitó antes. De lo contrario, solo seguirá la configuración en Configuración-Privacidad-Contacto.

Tuvimos algunos problemas con Yunas código en iOS6.1 en Xcode5. Con algunas pequeñas adaptaciones funcionó para mí.

El problema era que ARC en iOS 6 no permitía dispatch_release(sema);Aquí está el código de trabajo. Nota: ¡Lo uso en m_addressbooklugar de addressbookABAddressBookRef!

Si alguien tiene problemas con la libreta de direcciones en iOS5, use

ABAddressBookRef addressBook = ABAddressBookCreate(); 

Insted de

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL,NULL);

ABAddressBookRequestAccessWithCompletion(ABAddressBookCreateWithOptions(NULL, nil), ^(bool granted, CFErrorRef error) {
        dispatch_async(dispatch_get_main_queue(), ^{
            if (!granted){
                    [[[UIAlertView alloc] initWithTitle:@"Contacts Access Denied"
                                                message:@"This app requires access to your device's Contacts.\n\nPlease enable Contacts access for this app in Settings / Privacy / Contacts"
                                               delegate:nil
                                      cancelButtonTitle:@"Dismiss"

Para agregar una descripción al uso de alertas en InfoPlist.strings.

NSContactsUsageDescription = "TESTING!";

Swift 3. No olvides importar contactos

func requestForContactAccess(completionHandler: @escaping (_ accessGranted: Bool) -> Void) {
    let authorizationStatus = CNContactStore.authorizationStatus(for: CNEntityType.contacts)
    switch authorizationStatus {
    case .authorized:
        completionHandler(true)
    case .denied, .notDetermined:
        self.contactStore.requestAccess(for: CNEntityType.contacts, completionHandler: { (access, accessError) -> Void in
            if access {
                completionHandler(access)
            } else {
                if authorizationStatus == CNAuthorizationStatus.denied {
                    DispatchQueue.main.async(execute: { () -> Void in
                        let message = "\(accessError!.localizedDescription)\n\nPlease allow the app to access your contacts through the Settings."
                        self.showMessage(message: message)
                    })
                }
            }
        })
    default:
        completionHandler(false)
    }
}

Según la documentación de desarrollo de Apple reciente de iOS, Apple insiste en usar Contact además de AddressBook .

CNAuthorizationStatus authorizationStatus = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    switch (authorizationStatus) {
        case CNAuthorizationStatusNotDetermined: {

            break;
        }
        case CNAuthorizationStatusRestricted: {

            break;
        }
        case CNAuthorizationStatusDenied:{

            return;
        }
            break;
        case CNAuthorizationStatusAuthorized: {

            break;
        }
    }

El código c del objetivo anterior ayuda a encontrar el permiso de acceso de contacto meteorológico otorgado o no.

Con iOS 6 tienes que pedir permiso así
