如何在通讯簿联系人上设置即时消息属性？

Question

我尝试使用以下代码设置要添加到通讯簿的新联系人的 AIM 和 Skype 属性：

ABRecordRef record = ABPersonCreate();
CFErrorRef an_error = NULL;

ABMutableMultiValueRef multi_aim = ABMultiValueCreateMutable(kABMultiStringPropertyType);
ABMultiValueAddValueAndLabel(multi_aim, @"ExampleNick", kABPersonInstantMessageServiceAIM, NULL);
ABRecordSetValue(record, kABPersonInstantMessageProperty, multi_aim, &an_error);

ABMutableMultiValueRef multi_skype = ABMultiValueCreateMutable(kABMultiStringPropertyType);
ABMultiValueAddValueAndLabel(multi_skype, @"example.nick", kABPersonInstantMessageServiceSkype, NULL);
ABRecordSetValue(record, kABPersonInstantMessageProperty, multi_skype, &an_error);

if (an_error != NULL) {
    NSLog(@"Error while creating person");
}

CFErrorRef error = NULL;
ABAddressBookRef address_book = ABAddressBookCreateWithOptions(NULL, &error);
ABAddressBookRequestAccessWithCompletion(address_book, ^(bool granted, CFErrorRef error) {
    if (!granted) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error"
                                                        message:@"Unable to access address book"
                                                       delegate:self
                                              cancelButtonTitle:nil
                                              otherButtonTitles:nil];
        [alert show];
    } else {
        BOOL is_added = ABAddressBookAddRecord(address_book, record, &error);

        if (is_added) {
            NSLog(@"Address book entry added");
        } else {
            NSLog(@"ERROR adding address book entry: %@", error);
        }

        error = NULL;

        BOOL is_saved = ABAddressBookSave(address_book, &error);

        if (is_saved) {
            NSLog(@"Saved address book");
        } else {
            NSLog(@"ERROR saving address book: %@", error);
        }
    }

    CFRelease(record);
    CFRelease(multi_aim);
    CFRelease(multi_skype);
    CFRelease(address_book);
});

（我还添加了名字和姓氏，但为了简洁起见，将其排除在示例之外）

当记录被添加时，除了 AIM 和 Skype 字段之外的所有内容都会被填充。我做错了什么？

实例是 kABMultiDictionaryPropertyType 类型的多值属性。将一个 Skype id 插入 ABRecordRef 的片段如下所示。您可以在一个 ABRecordRef 中插入多个瞬间。

    ABRecordRef record = ABPersonCreate();
    NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:
        (NSString*)kABPersonInstantMessageServiceSkype, (NSString*)kABPersonInstantMessageServiceKey,
        @"YourSkypeIDGoesHere", (NSString*)kABPersonInstantMessageUsernameKey, 
        nil
    ];
    CFStringRef label = NULL; // in this case 'IM' will be set. But you could use something like = CFSTR("Personal IM");
    CFErrorRef error = NULL;
    ABMutableMultiValueRef values =  ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);
    BOOL didAdd = ABMultiValueAddValueAndLabel(values, (__bridge CFTypeRef)(dictionary), label, NULL);
    BOOL didSet = ABRecordSetValue(record, kABPersonInstantMessageProperty, values, &error);
    if (!didAdd || !didSet) {
        CFStringRef errorDescription = CFErrorCopyDescription(error);
        NSLog(@"%s error %@ while inserting multi dictionary property %@ into ABRecordRef", __FUNCTION__, dictionary, errorDescription);
        CFRelease(errorDescription);
    }
    CFRelease(values);
