ABAddressBook - 多个地址簿？
我正在构建一个从在线源同步联系人的应用程序。到目前为止，一切正常......当手机有一个地址簿时：
ABAddressBookRef addressBook = ABAddressBookCreate();
ABRecordRef group1 = ABGroupCreate();
ABRecordSetValue(group1,kABGroupNameProperty,@"Group1",nil);
ABAddressBookAddRecord(addressBook,group1,nil);
ABAddressBookSave(addressBook,nil);
ABRecordRef person = ABPersonCreate();
// Edit person values...
ABGroupAddMember(group1,person,nil);
ABAddressBookAddRecord(addressBook,person,nil);
ABAddressBookSave(addressBook,nil);
CFRelease(person);
CFRelease(addressBook);
但是当手机已经有多个地址簿时，就会出现问题。我正在一部手机上进行测试，该手机有一个用于所有联系人的地址簿，一个用于 Gmail 等。当我以上述方式添加联系人时，它会将其添加到 Gmail 地址簿，并在此过程中删除“Group1”标识符从接触。有没有办法可以更改 ABAddressBookRef 以指向手机内的特定地址簿？
I am building an app which syncs contacts from an online source. Everything works fine so far...when the phone has one address book:
ABAddressBookRef addressBook = ABAddressBookCreate();
ABRecordRef group1 = ABGroupCreate();
ABRecordSetValue(group1,kABGroupNameProperty,@"Group1",nil);
ABAddressBookAddRecord(addressBook,group1,nil);
ABAddressBookSave(addressBook,nil);
ABRecordRef person = ABPersonCreate();
// Edit person values...
ABGroupAddMember(group1,person,nil);
ABAddressBookAddRecord(addressBook,person,nil);
ABAddressBookSave(addressBook,nil);
CFRelease(person);
CFRelease(addressBook);
The problem occurs, however when the phone already has multiple address books. I am testing on a phone that has one address book for All Contacts, one for Gmail, etc. When I add a contact in the above manner, it adds it to the Gmail address book, and in the process strips the "Group1" identifier from the contact. Is there a way I can change the ABAddressBookRef to point to a specific address book within the phone?

根据 引用、
ABAddressBookCreate始终返回从系统地址簿数据库填充的地址簿对象。这意味着即使您有多个用于与其交互的ABAddressBook实例，也只有一本地址簿。According to the reference,
ABAddressBookCreatealways returns an address book object populated from the system's address book database. Which means there is only ever one address book, even if you have multiple instances ofABAddressBookthat you use to interact with it.迈克，你可能想看看这篇文章：
在 iOS 4+ 中从 ABAddressBook 获取特定的 ABSource
虽然我相信亚历克斯是对的，只有一本地址簿，该地址簿可能由多个来源（ABSource）组成。而且，在 iOS 4+ 中，可以专门识别和操作特定的源。
Mike, you might want to take a look at this post:
Obtaining Specific ABSource from ABAddressBook in iOS 4+
Although I believe Alex is right that there is only ever one address book, that address book may consist of multiple sources (ABSource). And, in iOS 4+ it is possible to specifically identify and manipulate particular sources.
