Objective c 从ABNewPersonViewController获取ABRecordRef'；s覆盖完成按钮点击

我有一个继承自

ABNewPersonViewController

的类，我已经重写了点击

Done

按钮时调用的方法。我的问题是，如何在自定义方法中访问

ABRecordRef

？这是我的密码：

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStylePlain target:self action:@selector(SaveMember)];
}



- (void)SaveMember
{
    NSString *firstName = (NSString *)CFBridgingRelease(ABRecordCopyValue(/*???? - This is where the ABRecordRef should go*/, kABPersonFirstNameProperty));

    [self dismissModalViewControllerAnimated:YES];
}

---

什么是ABRecordRef？它存储在哪里？如果我没有覆盖“完成”按钮，则调用的默认委托方法是：-（void）newPersonViewController:（ABNewPersonViewController*）newPersonViewController didCompleteWithNewPerson:（ABRecordRef）person。这包括ABRecordRef参数和人员的详细信息。这就是我在方法中需要访问的内容。
