从ABNewPersonViewController的Overrided Done Button Tap获取ABRecordRef

Question

我有一个继承自ABNewPersonViewController的类，并且我覆盖了点击Done按钮时调用的方法。 我的问题是，如何通过自定义方法访问ABRecordRef ？ 这是我的代码：

- (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];
}
