如何复制UIView无限次

Question

在我的应用中，有一部分必须在按下按钮时重复。也就是说，UIView，有几个文本字段，只要按下按钮就应该无限重复。为了更好地理解它，我正在上传一个＆＃34;演示视图＆＃34;页面和我用来实现它的代码。我能够复制视图和标签，但UIButton不会重复。

- (void)viewDidLoad {
    [super viewDidLoad];

    _testView.backgroundColor=[UIColor blackColor];
    [_testView addSubview:_labelRef];
    [_testView addSubview:_buttonRef];
    [self.view addSubview:_testView];
    _lastView=_testView;
        _archievedData=[NSKeyedArchiver archivedDataWithRootObject:_testView];

    // Do any additional setup after loading the view.
}

- (IBAction)repeatButton:(id)sender {

    UIView *newView=[NSKeyedUnarchiver unarchiveObjectWithData:_archievedData];
    CGRect newFrame;
    newFrame.origin.x=newView.frame.origin.x;
    newFrame.origin.y=(newView.frame.origin.y + newView.bounds.size.height);
    newFrame.size.height=newView.frame.size.height;
    newFrame.size.width=newView.frame.size.width;
    newView.frame=newFrame;
    newView.backgroundColor=[UIColor greenColor];
    [self.view addSubview:newView];
    _archievedData=[NSKeyedArchiver archivedDataWithRootObject:newView];
}

我该如何解决这个问题？
