推荐答案

致电 ABAddressBookCopyArrayOfAllPeople（）获取地址簿中所有人员记录的数组。然后按照文档：

Call ABAddressBookCopyArrayOfAllPeople() to get an array of all person records in the address book. Then follow the documentation:

要对一组人进行排序，请将函数CFArraySortValues与函数一起使用ABPersonComparePeopleByName作为比较器和ABPersonSortOrdering类型的上下文。用户所需的排序顺序（由ABPersonGetSortOrdering返回）通常是首选上下文。

To sort an array of people, use the function CFArraySortValues with the function ABPersonComparePeopleByName as the comparator and a context of the type ABPersonSortOrdering. The user’s desired sort order, as returned by ABPersonGetSortOrdering, is generally the preferred context.

以下代码清单显示了整个地址簿数据库的排序示例：

The following code listing shows an example of sorting the entire Address Book database:

ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFMutableArrayRef peopleMutable = CFArrayCreateMutableCopy(
                                          kCFAllocatorDefault,
                                          CFArrayGetCount(people),
                                          people
                                  );

 CFArraySortValues(
        peopleMutable,
        CFRangeMake(0, CFArrayGetCount(peopleMutable)),
        (CFComparatorFunction) ABPersonComparePeopleByName,
        (void*) ABPersonGetSortOrdering()
); 

CFRelease(addressBook);
CFRelease(people);
CFRelease(peopleMutable);
