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

Question

我使用ABAddressBookRegisterExternalChangeCallback在ios地址簿联系人更改时收到通知。

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。任何人都可以指导我，如何做到这一点？

你不能。你可以做的是，这将给你一个“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]; 
}
