stepper增加label的值，然后乘以init函数中的值从array中
我的表视图单元格

（cart tableView）服务选择单元格

（cart tableView）订购总单元格
class CartTotalTableViewCell: UITableViewCell { @IBOutlet weak var orderTotal: UILabel! @IBOutlet weak var OrderTax: UILabel! @IBOutlet weak var deliveryFee: UILabel! @IBOutlet weak var grandTotal: UILabel! override func awakeFromNib() { super.awakeFromNib() // Initialization code } override func setSelected(_ selected: Bool, animated: Bool) { super.setSelected(selected, animated: animated) // Configure the view for the selected state } }
如何选择步进器以增加标签值，如果选择上面是我正在使用的当前代码但是在单击步进器时崩溃，我该如何获取此值并将其发送到购物车vc以与定价信息相乘在Options数组中，将选定的项目数据发送到购物车中的服务选择单元格，或者将其乘以Service1ViewController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/减少他们的订单。 最初，您必须在dictionary存储默认值。 此链接适用于UISegmentedControl 。
在Storyboard本身中，设置UIStepper's minimumValue ， maximumValue和Step
var orderCount = [Int : Int]() override func viewDidLoad() { super.viewDidLoad() for i in 0...29 // TotaL number of rows { orderCount[i] = 1 // DEFAULT order count will be 1 } } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return 30 } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! SOTableViewCell cell.myStepper.tag = indexPath.row // ADDING TAG cell.testLbl.text = String(orderCount[indexPath.row]!) // PASS VALUES TO LABEL cell.myStepper.value = Double(orderCount[indexPath.row]!) // PASS VALUES TO STEPPER cell.selectionStyle = .none return cell } //ACTION should be in this ViewController. @IBAction func stepperAcn(_ sender: UIStepper) { print("sender.value ", sender.value) let getTag : Int = sender.tag orderCount[getTag] = Int(sender.value) tblVw.reloadData() }
