Obtenir toutes les adresses électroniques des contacts (iOS)

Je sais qu'il est possible de tirer un contact et consulter l'information basé sur un contact. Mais est-il possible d'obtenir tous les e-mails de contacts que vous avez entré les adresses e-mail, pour ensuite la stocker dans un NSArray?
C'est ma première fois de travailler avec des contacts donc je ne sais pas beaucoup sur elle.

    Oui, vous pouvez le faire. Il semble douteux que vous voulez faire (pourquoi avez-vous besoin de cette information?), mais il n'est pas difficile à faire.

    Vous pouvez utiliser ABAddressBookCopyArrayOfAllPeople pour obtenir un CFArrayRef à tous les gens, et puis vous pouvez interroger kABPersonEmailProperty de chacun à l'aide de ABRecordCopyValue. Le code devrait ressembler à quelque chose comme ceci (non testé):

    ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);
NSMutableArray *allEmails = [[NSMutableArray alloc] initWithCapacity:CFArrayGetCount(people)];
for (CFIndex i = 0; i < CFArrayGetCount(people); i++) {
    ABRecordRef person = CFArrayGetValueAtIndex(people, i);
    ABMultiValueRef emails = ABRecordCopyValue(person, kABPersonEmailProperty);
    for (CFIndex j=0; j < ABMultiValueGetCount(emails); j++) {
        NSString* email = (NSString*)ABMultiValueCopyValueAtIndex(emails, j);
        [allEmails addObject:email];
        [email release];
    }
    CFRelease(emails);
}
CFRelease(addressBook);
CFRelease(people);

    (Allocation de mémoire peut être un peu hors, ça a été un moment depuis que j'ai développé Cacao/Core code de la Fondation.)

    Mais sérieusement, la question de savoir pourquoi vous faites cela. Il ya une bonne chance qu'il y a une meilleure solution, en utilisant simplement l'Apple fournis par l'Api de présenter un sélecteur de contacts à des moments appropriés.
