Adding vCard data directly to the system Address Book

Question

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

is there a way to add the card data to the system Address Book d

Answer 1

Carter Allen's answer worked for me except that it caused my app to crash on the final statement CFRelease(book);

It turns out that the CFRelease(person); statement should be removed. Doing so stopped my app from crashing. See this answer for explanation https://stackoverflow.com/a/1337086/881103

Contacts is pretty forgiving and will do its best to import your vCard, however it seems that your address is not correct. There should be 7 parameters, separated by semicolons: PO box, Suite #, street address, city, state, ZIP, country. Most people leave off the PO box (and suite #), which is why a typical address has a semicolon (or two) at the beginning. If your address is ill-formed, parameters might end up in the wrong places.

The various fields in a vCard are terminated by a <return>: @"\r"

You don't need CHARSET=utf-8

Answer 3

If you're running on iOS 5 or later, this code should do the trick:

#import <AddressBook/AddressBook.h>

// This gets the vCard data from a file in the app bundle called vCard.vcf
//NSURL *vCardURL = [[NSBundle bundleForClass:self.class] URLForResource:@"vCard" withExtension:@"vcf"];
//CFDataRef vCardData = (CFDataRef)[NSData dataWithContentsOfURL:vCardURL];

// This version simply uses a string. I'm assuming you'll get that from somewhere else.
NSString *vCardString = @"vCardDataHere";
// This line converts the string to a CFData object using a simple cast, which doesn't work under ARC
CFDataRef vCardData = (CFDataRef)[vCardString dataUsingEncoding:NSUTF8StringEncoding];
// If you're using ARC, use this line instead:
//CFDataRef vCardData = (__bridge 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(vCardPeople);
CFRelease(defaultSource);
ABAddressBookSave(book, NULL);
CFRelease(book);
