子视图加载但 none 个按钮有效 ios swift

Question

我有一个自定义键盘项目，它的故事板包含一个 collectionView 和一个 scrollView。我还有一个用于搜索栏的 textField，它拉出一个包含键盘布局的笔尖，我可以使用它在键盘内进行搜索。当包含键盘的子视图变为活动状态时，我无法按任何按钮。我尝试在激活时将子视图置于前面，并尝试在隐藏 collectionView 时将主视图发送到后面。如何使用子视图中的按钮？

Before viewDidLoad

        if(self.key.txtSearch.text != "")
        {
            isCaps = false
            updateKeyBoard()
        }
    }


    @objc func typeSpaceKey(sender : UIButton)

请确保添加的子视图启用了用户交互，并且不会在超级视图中返回。
