我想将 ABRecordRef 添加到现有组。有些如何它不起作用。这是我的代码：

-(void)addUsers:(NSMutableArray*)users toGroupID:(ABRecordID)groupID {

    CFErrorRef error = NULL;
    ABAddressBookRef addressBookRef = ABAddressBookCreate();

   // Get Group 
    ABRecordRef group = ABAddressBookGetGroupWithRecordID(addressBookRef,groupID);

    for (User *user in users) {

        int recordId = user.uniqID;

        ABRecordRef person = ABAddressBookGetPersonWithRecordID(addressBookRef,(ABRecordID)recordId);

        //add the new person to the record
        ABAddressBookAddRecord(addressBookRef, person, nil); 
        ABAddressBookSave(addressBookRef, &error);

        // add the group   
        ABAddressBookAddRecord(addressBookRef, group, &error); 
        ABAddressBookSave(addressBookRef, &error);

        // add the person to the group 
        ABGroupAddMember(group, person, &error);         
        ABAddressBookSave(addressBookRef, &error);

        //save the record
        ABAddressBookSave(addressBookRef, nil);

        if (!isMemberAdded) {
            [self showAlertWithTitle:@"Alert" andMessage:@"Some Error Occured While Adding User to Existing Group"];
        }
    }
    BOOL isMembersAddedToGroup = ABAddressBookSave(addressBookRef, nil); 
    if (isMembersAddedToGroup) {
        [self showAlertWithTitle:@"Alert" andMessage:@"Selected Members Added to Existing Group Successfully"];
    }
    else{
        [self showAlertWithTitle:@"Alert" andMessage:@"Some Error Occured While Adding User to Existing Group"];
    }
    CFRelease(addressBookRef);
}

每当我使用上述代码并尝试将其保存在现有组中时，我都会在控制台中收到以下消息

CPSqliteStatementPerform: constraint failed for INSERT INTO ABGroupMembers (group_id, member_type, member_id) VALUES (?, ?, ?);
CPSqliteStatementReset: columns group_id, member_type, member_id are not unique for INSERT INTO ABGroupMembers (group_id, member_type, member_id) VALUES (?, ?, ?);

我没有得到上面代码中缺少的东西。感谢任何帮助。谢谢

如果我们看到消息：

CPSqliteStatementPerform: constraint failed for INSERT INTO ABGroupMembers (group_id, member_type, member_id) VALUES (?, ?, ?);
CPSqliteStatementReset: columns group_id, member_type, member_id are not unique for INSERT INTO ABGroupMembers (group_id, member_type, member_id) VALUES (?, ?, ?);

同样在文档中：

ABAddressBook 不透明类型（其实例称为地址簿）为地址簿提供了一个编程接口 - 一个由多个应用程序用来存储有关人员的个人信息的集中式数据库

（所以，在内部，这个错误是由于不正确的 sqlite 查询引起的。）

它表明ABGroupAddMemberorABAddressBookAddRecord(addressBookRef, group, &error);呼叫存在一些问题。

问题可能是：当我们调用ABAddressBookGetGroupWithRecordID和ABAddressBookGetGroupWithRecordID函数时，我们已经有了组和个人引用。

现在，当ABAddressBookAddRecord为 both(person和group) 执行时，它会将它们添加到addressbook但不更新它们的 UniqueIds ( id for person and group ref.)，因此在ABGroupAddMember函数调用时它具有person并且group具有相同的 id，这些 id 已添加到 ABGroupMembers表中。

请尝试在将它们添加到通讯簿之前和之后打印（以及在将它们添加到组之前recordId）person。group如果recordsIds没有更新，那就是原因，您需要获取recordnew recordId。还要检查新的person和group是否被添加到地址簿。
