我有一个objc功能：

<div class="container">
  <!-- Row -->
  <div class="row" id="product_list">
    <!-- Product -->
    <div class="col-xs-6 col-sm-3 product" id="belleza">
      <!-- Entry -->
      <div class="entry">
        <figure class="entry-thumbnail">
          <a href="#"><img alt="" src="../resources/images/productos/Shampoo-neutro.png"/></a>
        </figure>
        <div class="entry-body">
          <h3 class="entry-title">
            <a href="#">Shampoo Petra Neutro<br/></a>
          </h3>
          <h2 class="entry-title">
            <select id="presentaciones">
              <option id="shampoo-neutro260">Frasco Dosificador x260ml</option>
            </select>

          <div class="buttons">
            <a class="button add_to_cart_button" rel="nofollow">Add to cart</a>
          </div>
        </div>
      </div>
      <!-- End Entry -->
    </div>
    <!--End Col -->
  </div>
</div>

我正在尝试将其添加为gestureRecognizer的目标，但是当我点击分段控件时代码会一直崩溃。

@objc private func segmentedControlViewTapped(gestureRecognizer: UITapGestureRecognizer)

由于以下原因导致崩溃：发送无法识别的选择器

Answer 1

操作需要指向您指定的目标中的函数。

假设segmentedControlViewTapped在您的视图或控制器中，请更改您的代码：

let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(segmentedControlViewTapped(gestureRecognizer:)))

UITapGestureRecogniser添加目标不起作用
