ABRecordRef 字段似乎没有被填充？

Question

[背景：iOS 7、Xcode 5，都是截至 2014 年 2 月的最新版本。测试数据是 iPhone 5（真实设备，而非模拟器）]

我的目标是使用 AddressBookUI 方法允许用户指定联系人，然后使用各种字段（地址、电话号码等）在我的代码中填充 GUI。 ABPeoplePickerNavigationController 是允许用户按姓名选择联系人的标准机制。这样做会导致调用此委托方法：

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker 
shouldContinueAfterSelectingPerson:(ABRecordRef)person

但是，如果我此时检查人员记录，则多值字段都没有任何数据。所以我提取了RecordID，检索了它，结果ABRecordRef也没有填写多值字段。

如果我从委托方法返回 YES，则会向用户显示另一个 UI，并显示联系人详细信息。触摸任何字段都会导致此委托方法调用

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person 
property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier

并且ABRecordRef 已填写所有多值字段。

我找不到有关延迟加载记录的任何信息，或者存在所需的延迟或权限问题会阻止填写字段。我用来检查记录的代码是方法，因此在第二个实例中查找值的完全相同的代码无法在第一个实例中找到它。

关于可能发生的事情有什么建议，或者我如何在不向用户显示第二个 UI 的情况下检索完整记录？

我正在使用 Apple 的 QuickContacts 示例代码。以下是我所做的添加和更改。

+(NSMutableDictionary *)convertABRecordRef:(ABRecordRef)person

    // Initialize a mutable dictionary and give it initial values.
    NSMutableDictionary *contactInfoDict = [[NSMutableDictionary alloc] initWithCapacity:12];

    [contactInfoDict setObject:personIDNum forKey:@"recordID"];


    // Get the first name.
    if (generalCFObject)

编辑：添加我的解决方案（感谢 Thorsten！）。

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
    NSArray *allPersonRecords = (NSArray *)CFBridgingRelease(ABPersonCopyArrayOfAllLinkedPeople(person));
    NSLog(@"Count Linked People: %i", allPersonRecords.count);

    NSMutableDictionary *results = [[NSMutableDictionary alloc]initWithCapacity:12];
    for (int x=0; x<[allPersonRecords count]; x++)
    {
        ABRecordRef user = CFBridgingRetain([allPersonRecords objectAtIndex:x]);
        NSMutableDictionary *userFromArray = [QuickContactsViewController convertABRecordRef:user];
        [results addEntriesFromDictionary:userFromArray];  // mush them together
        CFRelease(user);
    }

    NSLog(@"finished! Total number of contact fields found:%d", [results count]);
    // do something with the data here...

    return NO;
}

Answer 1

一个人可以由多个人组成。遍历所有人以获取您的数据：

NSArray *people = (NSArray *)CFBridgingRelease(ABPersonCopyArrayOfAllLinkedPeople(person));
...
ABRecordRef user = CFBridgingRetain([people objectAtIndex:i]);
...
valuesRef = ABRecordCopyValue(user, kABPersonPhoneProperty);
valuesCount = 0;
if (valuesRef != nil) valuesCount = ABMultiValueGetCount(valuesRef);
...
