Answer 2

這裏是一個示例代碼做相同的：

- (void)delAllContacts { 
    ABAddressBookRef addressBook = CFBridgingRetain((__bridge id)(ABAddressBookCreateWithOptions(NULL, NULL))); 
    int count = ABAddressBookGetPersonCount(addressBook); 
    if(count==0 && addressBook!=NULL) { //If there are no contacts, don't delete 
     CFRelease(addressBook); 
     return; 
    } 
    //Get all contacts and store it in a CFArrayRef 
    CFArrayRef theArray = ABAddressBookCopyArrayOfAllPeople(addressBook); 
    for(CFIndex i=0;i<count;i++) { 
     ABRecordRef person = CFArrayGetValueAtIndex(theArray, i); //Get the ABRecord 
     BOOL result = ABAddressBookRemoveRecord (addressBook,person,NULL); //remove it 
     if(result==YES) { //if successful removal 
      BOOL save = ABAddressBookSave(addressBook, NULL); //save address book state 
      if(save==YES && person!=NULL) { 
       CFRelease(person); 
      } else { 
       NSLog(@"Couldn't save, breaking out"); 
       break; 
      } 
     } else { 
      NSLog(@"Couldn't delete, breaking out"); 
      break; 
     } 
    } 
    if(addressBook!=NULL) { 
     CFRelease(addressBook); 
    } 
}

+(BOOL)removedRecordFromAddressBookWithFirstValue:(NSString *)fullName{ 
    BOOL recordRemoved=NO; 
    CFErrorRef err; 
    ABAddressBookRef addressBook= 
    ABAddressBookCreateWithOptions(NULL,&err); 
    CFArrayRef people=ABAddressBookCopyArrayOfAllPeople(addressBook); 
    CFIndex nPeople=ABAddressBookGetPersonCount(addressBook); 
    NSString *currRecordFullName=[[NSString alloc] init]; 
    /*Invariant: No record with the name fullName has been 
     found so far.*/ 
    for(int i=0;i<nPeople;i++){ 
     ABRecordRef ref=CFArrayGetValueAtIndex(people,i); 
     CFErrorRef error=NULL; 
     currRecordFullName=nil; 
     currRecordFullName=[[NSString alloc] init]; 
     currRecordFullName= 
     (__bridge NSString *)ABRecordCopyCompositeName(ref); 
     if([currRecordFullName isEqualToString:fullName]){ 
      /*The record to be deleted has been found.*/ 
      ABAddressBookRemoveRecord(addressBook,ref,&error); 
      ABAddressBookSave(addressBook,&error); 
      CFRelease(ref); 
      CFRelease(addressBook); 
      if(error!=NULL){ 
       CFStringRef errorDesc=CFErrorCopyDescription(error); 
       NSLog(@"Failed to remove record: %@",errorDesc); 
       CFRelease(errorDesc); 
      }else{ 
       NSLog(@"Record removed"); 
       recordRemoved=YES; 
      } 
      break; 
     }else{;} 
    } 
    return recordRemoved; 
}
