Tableviews代理按钮单击

我有一个很大的UITableViewCell代表一个地方。单元格的元素是两个按钮 星形按钮 信息按钮 . 他们两个都有一个永远不会被执行的目标,我不知道为什么。。所有的触碰都被人吃掉了 didSelectRowAt 在tableview旁边。让我如此困惑的是,它在几个小时前运行良好,我没有改变两个按钮的属性。有人知道发生了什么吗?

    }
}

extension UIView {
  func anchor(top: NSLayoutYAxisAnchor?, leading: NSLayoutXAxisAnchor?, bottom: NSLayoutYAxisAnchor?, trailing: NSLayoutXAxisAnchor?,  paddingTop: CGFloat, paddingLeading: CGFloat, paddingBottom: CGFloat, paddingTrailing: CGFloat, width: CGFloat, height: CGFloat) {

    translatesAutoresizingMaskIntoConstraints = false

    if let bottom = bottom {
        bottomAnchor.constraint(equalTo: bottom, constant: -paddingBottom).isActive = true
    }

    if let trailing = trailing {

    }

    if width != 0 {
        widthAnchor.constraint(equalToConstant: width).isActive = true
    }

    if height != 0 {
        heightAnchor.constraint(equalToConstant: height).isActive = true
    }
}

表视图:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: OverviewTableViewCell.reuseIdentifier, for: indexPath) as! OverviewTableViewCell
    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    tableView.deselectRow(at: indexPath, animated: false)
    delegate?.pushTo()
}

单元格中的printBounds()函数显示框架和边界是正确的(我猜)
