我正在做一个应用程序表单，我想获取文本字段的值。问题是如何获取第一个单元格的值并与第二个单元格的valueField相乘。
除第一个单元格和结果单元格是尤里卡形式外，其他所有单元格均由Costum单元格制成。
我已经使用了两个文件：
ViewController.swift
import UIKit
import Eureka
class ViewController: FormViewController {
override func viewDidLoad() {
super.viewDidLoad()
var rules = RuleSet<String>()
form +++ Section("EINGABESUMME BRUTTO (EXXL MWST)")
{
$0.header?.height = { 20 }
}
<<< DecimalRow(){ row in
//row.value = 0
row.title = " "
row.tag = "MyRowTag"
row.placeholder="0.00"
row.cell.tag = KalkulationTag.eingabessumeBrutto.rawValue
}
.cellUpdate { cell, row in
cell.textField?.font = .boldSystemFont(ofSize: 18.0)
}
form +++ Section("ZIEL-DB PROJEKT BRUTTO")
{
$0.header?.height = { 20 }
}
<<< KalkulationRow { row in
//row.tag = "MyRowTag1"
row.cell.tag = KalkulationTag.zielBrutto.rawValue
// row.cell.valueField.text = "54.00"
// row.value = User(percentage: 45, value: 45)
}
form +++ Section("RABATT")
{
$0.header?.height = { 20 }
}
<<< KalkulationRow { row in
row.tag = "MyRowTag2"
// row.cell.percentageField.tag = KalkulationTag.rabatt.rawValue
}
.cellUpdate{cell, row in
//print("sevgjan")
}
form +++ Section("SKONTO")
{
$0.header?.height = { 20 }
}
<<< IntRow(){
$0.title = "Tage:"
$0.cell.tag = KalkulationTag.tage.rawValue
$0.add(rule: RuleRequired())
$0.tag = "tage"
}
.cellUpdate { cell, row in
cell.textField?.font = .boldSystemFont(ofSize: 18.0)
}
<<< KalkulationRow { row in
row.cell.valueField.tag = KalkulationTag.skonto.rawValue
row.cell.percentageField.tag = KalkulationTag.skontoPercent.rawValue
//row.cell.percentageField.text = "54"
}
.cellUpdate { cell, row in
if cell.tag == KalkulationTag.skonto.rawValue {
print("rijiljgjd554")
}
}
form +++ Section("DIVERSE ABZUGE")
{
$0.header?.height = { 20 }
}
<<< KalkulationRow { row in
//row.cell.valueField.text = "54.00"
row.cell.tag = KalkulationTag.diverse.rawValue
}
form +++ Section("EINGABESSUME NETTO")
{
$0.header?.height = { 20 }
}
<<< DecimalRow(){
$0.title = " "
// $0.value = 0
$0.placeholder = "0.00"
$0.placeholderColor = UIColor.green
$0.cell.tag = KalkulationTag.result.rawValue
}
.cellUpdate { cell, row in
cell.textField?.font = .boldSystemFont(ofSize: 18.0)
cell.textField?.textColor = UIColor.green
// cell.textField?.isUserInteractionEnabled = false
}
form +++ Section("ZIEL-DB PROJEKT NETTO")
{
$0.header?.height = { 20 }
}
<<< KalkulationRow { row in
row.cell.tag = KalkulationTag.zielNetto.rawValue
//row.cell.valueField.text = "54.00"
}
}
}
这是KalkulationCell.swift
