计算应用错误

Question

我希望应用程序开头的第一个单元格值和result（green）值相同 这是项目的图片

我正在使用的代码-

import Foundation
import Eureka


final class KalkulationCell: Cell<User>, CellType , UITextFieldDelegate{


   // var vlera = ""

    @IBOutlet var percentageField: UITextField!
    @IBOutlet var valueField: UITextField!

    required init(style: UITableViewCellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override func setup() {
        super.setup()
        // we do not want our cell to be selected in this case. If you use such a cell in a list then you might want to change this.
        percentageField.delegate = self
        selectionStyle = .none


        //        percentageField.text = "25.00"
        // define fonts for our labels
        percentageField.font = .systemFont(ofSize: 18)
        valueField.font = UIFont.boldSystemFont(ofSize: 18.0)

        percentageField.textColor=UIColor.black
        // percentageField.font = UIFont.boldSystemFont(ofSize: 18.0)
        // specify the desired height for our cell
        //height = { return 94 }

        // set a light background color for our cell
        // backgroundColor = UIColor(red:0.984, green:0.988, blue:0.976, alpha:1.00)
    }

    override func update() {
        super.update()


        // get the value from our row

        guard let user = row.value else { return }
        //
        percentageField.text = user.percentage.description
        valueField.text = user.value.description
    }



    func textFieldDidEndEditing(_ textField: UITextField) {

calculate()

    }
    func calculate(){

        let row: DecimalRow = (formViewController()?.form.rowBy(tag: "MyRowTag"))!
        let row2: DecimalRow = (formViewController()?.form.rowBy(tag: "test"))!

        var perqindja = Double(percentageField.text!)
        var vlera = Double(valueField.text!)
            if let vlera1 = row.value{

                if perqindja != nil {

                    let kosto = (row.value)!*perqindja!*0.01
                    valueField.text  = kosto.description
                    let exclamationMark: Character = "%"
                    percentageField.text?.append(exclamationMark)
                    valueField.isUserInteractionEnabled = false
                    valueField.reloadInputViews()
                }else if vlera != nil {
                    // perqindja = Double(percentageField.text!)
                    let kosto1 = round((vlera!/(row.value)!)*100)

                    percentageField.text  = kosto1.description
                    let exclamationMark: Character = "%"
                    percentageField.text?.append(exclamationMark)
                    percentageField.isUserInteractionEnabled = false
                     percentageField.reloadInputViews()
                }
            }
            else{
            }
    }

    func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {

        if let text = textField.text,
            !text.isEmpty {
            textField.text?.removeLast()
            //valueField.text?.removeAll()
        }
calculate()

        return formViewController()?.textInputShouldBeginEditing(textField, cell: self) ?? true
    }

}


struct User: Equatable {

    var percentage: String
    var value: String

}
func ==(lhs: User, rhs: User) -> Bool {
    return lhs.percentage == rhs.percentage
}


final class KalkulationRow: Row<KalkulationCell>, RowType {
    required init(tag: String?) {
        super.init(tag: tag)
        cellProvider = CellProvider<KalkulationCell>(nibName: "KalkulationCell")
    }
}

  

让行：DecimalRow =（formViewController（）?. form.rowBy（tag：   “ MyRowTag”））！ -此代码称为第一个单元格

     

让row2：DecimalRow =（formViewController（）?. form.rowBy（tag：   “测试”））！ -此代码调用结果单元格（绿色）
