IOS Get system Contacts

Get to the point of getting the system Address book, do not want to talk more, leave the link http://my.oschina.net/joanfen/blog/140146

Usual procedure:

First create an object addressbooks for the Abaddressbookref class, and then get the system permissions,

Code to get permission:

 //  get system permissions and get the Address book contents into Addressbooks.     abaddressbookref addressbooks = nil;    Addressbooks  = Abaddressbookcreatewithoptions (null, NULL); dispatch_semaphore_t Sema  = dispatch_semaphore_create (0  ); Abaddressbookrequestaccesswithcompletion (Addressbooks,  ^ (bool   Granted, cferrorref error) {dispatch_semaphore_signal (SEMA);    });    Dispatch_semaphore_wait (Sema, dispatch_time_forever);        Dispatch_release (SEMA);  //  get everyone in the Address book  Cfarrayref Allpeople = Abaddressbookcopyarrayofallpeople (addressbooks); 

It then creates an object Allperson of the Cfarrayref class, accepting adressbooks through Abaddressbookcopyarrayofallpeople (addressbooks).

Then create a Abrecordref class object person, but in fact he is not really a class that contains address book information, this abrecordref is just a record.

The next step is to create the person object by using the method:

Ab_extern cftyperef abrecordcopyvalue (abrecordref record, Abpropertyid property);

To get what information, the property writes Abpropertyid this type of variable, in fact Abpropertyid is a int32_t type variable.
