[背景：iOS 7，Xcode 5，两者都是截至2014年2月的最新版本。测试数据是一个地址簿条目，除了基本联系信息外，还有多个电话号码和多个地址，在iPhone 5上（真实设备，不是模拟器）]
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）填充我的代码中的GUI。 ABPeoplePickerNavigationController是允许用户按名称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。因此，我提取了RecordID，检索了该内容，结果ABRecordRef也没有填充多值字段。
如果我从委托方法返回YES，则会向用户显示另一个显示联系人详细信息的UI。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ABRecordRef填写了所有多值字段。
我找不到有关延迟加载的记录的任何信息，或者存在所需的延迟或权限问题，这会阻止填写字段。我用来检查记录的代码是方法，所以在第二个实例中找到值的完全相同的代码无法在第一个实例中找到它。
有关可能发生的事情的任何建议，或者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。以下是我所做的补充和更改。

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;
}
答案 0 :(得分：2)
一个人可以由多人组成。迭代所有人来获取您的数据：
NSArray *people = (NSArray *)CFBridgingRelease(ABPersonCopyArrayOfAllLinkedPeople(person));
...
ABRecordRef user = CFBridgingRetain([people objectAtIndex:i]);
...
valuesRef = ABRecordCopyValue(user, kABPersonPhoneProperty);
valuesCount = 0;
if (valuesRef != nil) valuesCount = ABMultiValueGetCount(valuesRef);
...
