ABAddressBookGetPersonWithRecordID returns 空

Question

在我的应用程序中，我从联系人中选择 phone 号码。我需要存储记录 ID，然后检索 recordref。为了测试逻辑，我尝试了以下示例在下面的委托中，我获取了此人的记录 ID。然后尝试检索 Recordref。记录器 (gref) 为空请让我知道我做错了什么。我已经在 iPhone 6 和 os 8.2

上测试过这个

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person
{

     ABRecordID sid = ABRecordGetRecordID(person);

     ABAddressBookRef addressBook = ABAddressBookCreate();

     ABRecordRef gref = ABAddressBookGetPersonWithRecordID(addressBook, sid);

     NSLog(@“org record ref %@",person);

     NSLog(@“new record ref %@",gref);

}

在使用通讯录之前，我们需要获得访问通讯录的权限。例子

CFErrorRef myError = NULL;
ABAddressBookRef myAddressBook = ABAddressBookCreateWithOptions(NULL, &myError);

__block ABRecordRef gref;

ABAddressBookRequestAccessWithCompletion(myAddressBook,
                                         ^(bool granted, CFErrorRef error) {
                    if (granted) {

                        gref = ABAddressBookGetPersonWithRecordID(myAddressBook, sid);
                        NSString *contactName = CFBridgingRelease(ABRecordCopyCompositeName(gref));

                        NSLog(@"after record ref %@",gref);
                        NSLog(@"human name %@",contactName);

                    } else {

                        // Handle the case of being denied access and/or the error.

                    }

                                             CFRelease(myAddressBook);

            });
