Demande programmée d'accès aux contacts

Question

Depuis la mise à jour vers iOS 6, j'ai remarqué que mon code pour ajouter un contact au carnet d'adresses de l'iPhone ne fonctionne plus. Je pense qu'il s'agit d'un problème lié à la permission, puisque Apple demande maintenant la permission de l'utilisateur avant d'accéder aux contacts (correction de ce problème -> http://www.cultofmac.com/179733/19-of-ios-apps-access-your-address-book-without-your-permission-until-ios-6-report/ ).

Je m'attendais à ce que l'application demande automatiquement la permission d'accéder aux contacts, comme dans la capture d'écran ci-dessous, mais elle ne le fait pas. La tentative d'ajouter le contact échoue avec le message suivant ABAddressBookErrorDomain error 1 .

Dois-je lancer de manière programmatique la boîte de dialogue de demande d'accès aux contacts ? Comment cela se fait-il ?

Answer 1

Conformément à cette documentation sur le site d'apple (faites défiler la page jusqu'à Privacy au milieu de la page), accès au carnet d'adresses doivent être accordées avant de pouvoir y accéder par programme. Voici ce que j'ai fini par faire.

  #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
  }

Cela a fait l'affaire pour moi !

Dans iOS6, Apple a introduit un nouveau contrôle de confidentialité, l'utilisateur peut contrôler l'accès aux contacts et aux calendriers par chaque application. Donc, dans le code, vous devez ajouter un moyen de demander la permission. Dans iOS5 ou avant, nous pouvons toujours appeler

ABAddressBookRef addressBook = ABAddressBookCreate();

pour obtenir le carnet d'adresses sans problème, mais dans iOS6, si vous n'avez pas la permission, cet appel retournera simplement un pointeur vide. C'est pourquoi nous devons changer la méthode pour obtenir 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.
}

Dans le code, le sémaphore est utilisé pour bloquer jusqu'à la réponse, tandis que ABAddressBookRequestAccessWithCompletion demandera la permission si l'application ne l'a pas demandé avant. Sinon, elle suivra simplement les paramètres dans Settings-Privacy-Contact.

Answer 4

J'ai eu quelques problèmes avec yunas sur iOS6.1 dans Xcode5. Avec quelques petites adaptations ça a marché pour moi.

Le problème était que l'ARC dans iOS 6, ne permettait pas dispatch_release(sema); Voici le code de travail. Note : J'utilise m_addressbook au lieu de addressbook comme ABAddressBookRef !

ViewController.m

#import "ViewController.h"
#import <AddressBook/AddressBook.h>
#import <AddressBook/ABAddressBook.h>
#import <AddressBook/ABPerson.h>

@interface ViewController ()

@property (nonatomic, strong) NSMutableArray* contactList;

@end

@implementation ViewController

- (void)viewDidLoad
{
  [super viewDidLoad];

  ABAddressBookRef m_addressbook =  ABAddressBookCreateWithOptions(NULL, NULL);

  __block BOOL accessGranted = NO;
  if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
      dispatch_semaphore_t sema = dispatch_semaphore_create(0);
      dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
          @autoreleasepool {
              // Write your code here...
              // Fetch data from SQLite DB
          }
      });

      ABAddressBookRequestAccessWithCompletion(m_addressbook, ^(bool granted, CFErrorRef error) {
          accessGranted = granted;
          dispatch_semaphore_signal(sema);
      });
      dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
  }
  else { // we're on iOS 5 or older
      accessGranted = YES;
  }

  if (accessGranted) {
  // do your stuff
  }
}
