Question

我正在设计一个二维码阅读器，它需要检测和导入vCard格式的联系卡（.vcf）。

有没有办法直接将卡数据添加到系统地址簿，还是我需要自己解析vCard并单独添加每个字段？

Answer 1

如果您在iOS 5或更高版本上运行，此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);

确保链接到项目中的AddressBook框架。

Carter Allen的回答对我有用，只不过它导致我的应用程序在最终声明中崩溃CFRelease(book);

事实证明应删除CFRelease(person);语句。这样做会阻止我的应用崩溃。请参阅此答案以获取解释https://stackoverflow.com/a/1337086/881103

Answer 3

联系人非常宽容，并会尽力导入您的vCard，但似乎您的地址不正确。应该有7个参数，用分号分隔：PO框，套件＃，街道地址，城市，州，ZIP，国家。大多数人都离开了邮政信箱（和套件＃），这就是典型地址在开头有一个分号（或两个）的原因。如果您的地址格式错误，参数可能会在错误的位置结束。

vCard中的各个字段由<return>终止：@“\ r”

您不需要CHARSET=utf-8

将vCard数据直接添加到系统通讯簿中
