当上面选择的是我正在使用的当前代码，但单击步进器时会崩溃，我如何编程步进器以增加标签的值，以及如何获取此值并将其发送到购物车vc以与选项数组中的定价信息相乘，并将所选项目数据发送到购物车中的服务选择单元格，或者在Service1ViewController中将其相乘，并将总数据发送到购物车，同时将所选项目数据发送到服务选择单元格？

我为添加到购物车屏幕做了示例。用户可以增加/减少订单。最初，您必须在

你在使用故事板吗？是的，init函数是另一个类的狙击手，如果你想让我发布我很乐意做的所有代码，那么Stepper在UITableViewCell中。每个单元格，你必须增加/减少你的顺序。是吗？是的，在表格视图的swift文档中，我有更新UIStepper基本答案。你可以改变它。有了这个，你可以根据你的需要进行定制。我需要解释更多关于UIStepper的操作应该在UIViewController中。与**cell.quantityStepper.addTarget（self，action:#selector（setter:cell.stepperLabel.text），for:.valueChanged）**不同，我修改了帖子以使我的问题可以理解，我感谢您的快速回复，但并非您发布的所有内容都与我的整个问题1相关。cell.stepper=步骤[indexPath.row]。这是什么？2.  @iAction func valueChanged（uSender:AnyObject）{print（“Method.valueChanged activated”）//更新stepperlabel stepperlabel.text=String（Int（quantityStepper.value））}在UIViewController中执行此操作，而不是在UITableViewCelk中执行此操作我知道我必须在UIViewController中执行此操作，但关于问题的其余部分，比如将该值乘以定价整数（这也是我应该使用double来显示小数的另一个问题）并将数据移动到cartVC
