检测从ABAddressBookRegisterExternalChangeCallback更改的内容 [英] Detect what was changed from ABAddressBookRegisterExternalChangeCallback
本文介绍了检测从ABAddressBookRegisterExternalChangeCallback更改的内容的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用ABAddressBookRegisterExternalChangeCallback来获取用户的AddressbookBook中的外部更改。我使用以下代码注册回调：
I am using ABAddressBookRegisterExternalChangeCallback to get the external changes in AddressbookBook of the user. I am using the following code to register the callback:
ABAddressBookRef ntificationaddressbook = ABAddressBookCreate();
ABAddressBookRegisterExternalChangeCallback(ntificationaddressbook, MyAddressBookExternalChangeCallback, self);
当调用此回调时，成功调用MyAddressBookExternalChangeCallback
and when this callback is called then MyAddressBookExternalChangeCallback is called successfully
void MyAddressBookExternalChangeCallback (ABAddressBookRef ntificationaddressbook,CFDictionaryRef info,void *context)
{
NSLog(@"Changed Detected......");
}
我有以下问题：
- 如何检测哪些联系人已更改，以及在该联系人上执行了哪些操作（添加，更新，删除）。我需要获得该联系人的recordID。可能吗 ？
- How can i detect which contacts was changed, and which action (ADD,Update,Delete) was performed on that Contact. I need to get the recordID of that contact. Is it Possible ?
不幸的是，如果那不可能，那么像viber，tango，watsapp这样的应用程序如何获取更改信息？
Unfortunately if thats not possible then how the apps like viber, tango, watsapp gets the change information ?
- 只有当应用程序处于后台时才能获得回调方法，如果应用程序被终止，则可以通过任何方式获取更改通知。
请帮忙。在此先感谢。
推荐答案
我找到了解决方案来查找地址簿中的更改内容。我不确定它是否是一个精确的，但有些是如何工作的。
I found the solution to find what was changed in the addressbook. I am not sure if its a precise one, But some how that works.
为地址簿创建一个回调通知： -
Create a Callback Notification for Addressbook:-
ABAddressBookRef ntificationaddressbook = ABAddressBookCreate();
ABAddressBookRegisterExternalChangeCallback(ntificationaddressbook, MyAddressBookExternalChangeCallback, self);
比发生通知时添加以下代码： -
Than Add the following code when notification Occurs:-
void MyAddressBookExternalChangeCallback (ABAddressBookRef ntificationaddressbook,CFDictionaryRef info,void *context)
{
NSTimeInterval timeStampone = [[NSDate date] timeIntervalSince1970];
NSNumber *timeStamponeobj= [NSNumber numberWithDouble: timeStampone];

for (CFIndex i=0; i < count; i++) {
