回答1:

 #import<AddressBook/AddressBook.h> 

 ABAddressBookRef addressBook = ABAddressBookCreate();

 CFArrayRef all = ABAddressBookCopyArrayOfAllPeople(addressBook); 

 CFIndex n = ABAddressBookGetPersonCount(addressBook); 

 for( int i = 0 ; i < n ; i++ ) 

   { 

      ABRecordRef ref = CFArrayGetValueAtIndex(all, i); 

      ABMultiValueRef contactnumber = ABRecordCopyValue(ref, kABPersonPhoneProperty);

      for(CFIndex j = 0; j < ABMultiValueGetCount(contactnumber); j++)

          { 

               CFStringRef contactnumberRef = ABMultiValueCopyValueAtIndex(contactnumber, j);

               NSString *contactnumberstr = (NSString *)contactnumberRef;

               CFRelease(contactnumberRef); [self.contactnumberArray contactnumber]; 

               [contactnumber release]; 
          } 
   }

you will get the contacts in array of "self.contactnumberArray".

Enjoy!
