ios - 如何从 ABAddressBookRegisterExternalChangeCallback 获取更新的联系人列表？

Question

我ABAddressBookRegisterExternalChangeCallback用来在 ios 通讯录联系人更改时获取通知。

如何从回调中获取更新（添加/删除/修改）联系人列表？我不想再次重新加载我的整个联系人列表。

我似乎无法在文档中的任何地方找到它。谁能指导我，如何做到这一点？

Answer 1

你不能。您可以做的是这将为您提供“在给定时间内修改”的联系人列表，例如：

void MyAddressBookExternalChangeCallback (ABAddressBookRef notifyAddressBook,CFDictionaryRef info,void *context)
{        
    //The addressbook object get's updated.


    CFArrayRef peopleRefs = ABAddressBookCopyArrayOfAllPeopleInSource(notifyAddressBook, kABSourceTypeLocal);



    ABAddressBookRevert(notifyAddressBook);

    CFIndex count = CFArrayGetCount(peopleRefs);

    for (CFIndex i=0; i < count; i++) {
        ABRecordRef ref = CFArrayGetValueAtIndex(peopleRefs, i);
        NSDate* datemod = (__bridge_transfer NSDate *)(ABRecordCopyValue(ref, kABPersonModificationDateProperty));


        NSTimeInterval distanceBetweenDates = [[NSDate date] timeIntervalSinceDate:datemod];

        int seconds = round(distanceBetweenDates);

        if(seconds < 60){

            ABCPerson * person = [[ABCFacade sharedABCFacade] convertABRecordRef:ref];
            NSLog(@"modifactiondate: %@", [person modificationdate]);

            [[ABCFacade sharedABCFacade] replacePersonInPersonListWithPerson:person];

        }
    }


    NSLog(@"Yes it does get called by this change %@", context);

    [[ABCFacade sharedABCFacade] ABRefresh];   
}
