我已经通过代码创建了 UIView（比如 A）对象，并通过代码添加了所有子视图，如 UIButton、UILabel 等。我在 XIB 中创建的另一个 UIView（比如 B）。现在我正在尝试将 A 分配给 B。当我在分配后记录 B 的子视图时，我可以在 B 中看到 A 的所有子视图，但视图中什么也没有出现。我知道我的逻辑可能是错误的，但我没有明白。请让我知道它是否可能！

这是我的代码：

- (UIView*)createButtonView:(NSInteger)viewTag avatarImageName:(NSString*)avatarImageName cardImageName:(NSString*)cardImageName ballImageName:(NSString*)ballImageName
{
    buttonBGView = [[UIView alloc] initWithFrame:CGRectMake(15,86,290,290)];
    buttonBGView.tag = viewTag;

    UIImageView *avatarImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 206, 84, 84)];
    avatarImageView.image = [UIImage imageNamed:avatarImageName];
    [buttonBGView addSubview:avatarImageView];

    UIButton *temoCardButton  = [[UIButton alloc] initWithFrame:CGRectMake(58, 42, 188, 222)];
    temoCardButton.tag = viewTag;
    [temoCardButton setImage:[UIImage imageNamed:cardImageName] forState:UIControlStateNormal];
    [temoCardButton addTarget:self action:@selector(cardButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
    [buttonBGView addSubview:temoCardButton];

    UILabel *scoreLabel = [[UILabel alloc] initWithFrame:CGRectMake(228, 0, 30, 30)];
    scoreLabel.text = [cardPointsArray objectAtIndex:randomIndex];
    scoreLabel.textAlignment = UITextAlignmentCenter;
    [buttonBGView addSubview:scoreLabel];

    buttonBGView.backgroundColor = [UIColor redColor];

    return buttonBGView;
}


-(void)cardButtonTapped:(id)sender
{
    NSLog(@"%@",[buttonBGView subviews]);

    self.cardTappedView = buttonBGView;

    NSLog(@"%@",[self.cardTappedView subviews]);
}

谢谢
