将 vCard 数据直接添加到系统地址簿

我正在设计一个QR码阅读器，它需要检测并导入vCard格式（.vcf）的联系人卡片。

有没有办法直接将名片数据添加到系统地址簿中，或者我需要自己解析vCard并单独添加每个字段？

如果您在 iOS 5 或更高版本上运行，以下代码应该可以解决问题：

#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);
