iphone - 将人员组添加到 ABAddressBookRef，组添加正常，但人员未添加到组？

我有几行 Objective-C 代码，例如:

ABAddressBookRef addressBook;
CFErrorRef error = NULL;
addressBook = ABAddressBookCreate();
ABRecordRef group = ABGroupCreate();
ABRecordSetValue(group, kABGroupNameProperty,@"My Group", &error);

ABRecordRef person = ABPersonCreate();
ABRecordSetValue(person,kABPersonFirstNameProperty,@"Huy 1111111",&error);
ABRecordSetValue(person,kABPersonLastNameProperty,@"AseDra",&error);
ABGroupAddMember(group, person, &error);

ABAddressBookAddRecord(addressBook, group, &error);

ABAddressBookSave(addressBook,&error);

它运行正常，没有错误，组已添加到模拟器通讯簿但人没有添加到模拟器通讯簿。谁能告诉我哪里错了？

根据 iOS 的通讯簿编程指南(下面的链接)，通讯簿中必须存在人员记录，然后才能将其添加到组中。

“在可以将人员记录添加到组之前，它必须已经保存到通讯簿数据库。”

所以也许这会起作用

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

ABRecordRef person = ABPersonCreate();
ABRecordSetValue(person,kABPersonFirstNameProperty,@"Huy 1111111",&error);
ABRecordSetValue(person,kABPersonLastNameProperty,@"AseDra",&error);

// add the person record
ABAddressBookAddRecord(addressBook, person, &error);

ABRecordRef group = ABGroupCreate();
ABRecordSetValue(group, kABGroupNameProperty,@"My Group", &error);
ABGroupAddMember(group, person, &error);
ABAddressBookAddRecord(addressBook, group, &error);

ABAddressBookSave(addressBook,&error);
