I am designing a QR code reader, and it needs to detect and import contact cards in vCard format.

is there a way to add the card data to the system Address Book directly, or do I need to parse the vCard myself and add each field individually?

I will be getting the VCArd in a NSString format

I tried the code below (from a different post) and didn't work

-(IBAction)saveContacts{
NSString *vCardString = @"vCardDataHere";
CFDataRef vCardData = (__bridge_retained CFDataRef)[vCardString dataUsingEncoding:NSUTF8StringEncoding];

ABAddressBookRef book = ABAddressBookCreate();
ABRecordRef defaultSource = ABAddressBookCopyDefaultSource(book);
CFArrayRef vCardPeople = ABPersonCreatePeopleInSourceWithVCardRepresentation(defaultSource, vCardData);
for (CFIndex index = 0; index < CFArrayGetCount(vCardPeople); index++) {
    ABRecordRef person = CFArrayGetValueAtIndex(vCardPeople, index);
    ABAddressBookAddRecord(book, person, NULL);
    CFRelease(person);
}

CFRelease(vCardPeople);
CFRelease(defaultSource);
ABAddressBookSave(book, NULL);
CFRelease(book);
}

I have searched a bit and fixed the code and here how it looks like it doesn t crash anymore but it doesn t save the VCard (NSString format) in the address book , any clues ?
