"iOS Dev-114" Abaddressbook Address Book: Simple Introduction to additions and deletions, cf frame conversion between f frames

(1) After importing the Abaddressbook library, and then adding the header file, you can use it.

-Because this library method is basically the C language style, so the class is basically a CF beginning, such as Cfstringref and Cfarrayref, it and OC NSString and Nsarray similar, can be converted to each other, using __bridge to cast, such as (__ Bridge NSString *) XXX, you can convert the original cfstringref xxx to nsstring type, the advantage is that there is no need to release operations in many places Cfrelease ().

--Using the Address book, the first need to send an access request, to obtain a request, before a series of operations, access to the request is the method of Abaddressbookrequestaccesswithcompletion, It is recommended that in the subsequent implementation of some address book operations can determine whether the authorization we access is still there, if the user changed the authorization, we do not have to further the operation, and the method is judged:

Before clicking, first determine if the IF (Abaddressbookgetauthorizationstatus ()!=kabauthorizationstatusauthorized) return is allowed;

--In addition to query, add, modify, delete, all need to finally save the Address Book, equivalent to do an update operation.

Save Abaddressbooksave (Bookref, NULL);

--The delete operation is:

Abaddressbookremoverecord (Bookref, people, NULL);

The main code is as follows:
