我正在用Eureka表单制作一个应用程序,问题是我不知道如何获取第一个textField的值。
问题是我应该获取第一部分DecimalRow的值,并且应该将其与第二部分KalkulationCell(这是一个自定义单元格)的textField相乘,而我不知道如何合并这些部分。 / p>
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(){
$0.title = " "
//$0.value = 54
$0.tag = "MyRowTag"
}
.cellUpdate { cell, row in
cell.textField?.font = .boldSystemFont(ofSize: 18.0)
}
let row: DecimalRow? = form.rowBy(tag: "MyRowTag")
let value = row?.value
// Get the value of all rows which have a Tag assigned
// The dictionary contains the 'rowTag':value pairs.
let valuesDictionary = form.values()
print(valuesDictionary)
form +++ Section("ZIEL-DB PROJEKT BRUTTO")
{
$0.header?.height = { 20 }
}
<<< KalkulationRow {
row in
row.cell.valueField.text = "54.00"
row.tag="hello"
}
form +++ Section("RABATT")
{
$0.header?.height = { 20 }
}
<<< KalkulationRow { row in
row.cell.valueField.text = "54.00"
}
form +++ Section("SKONTO")
{
$0.header?.height = { 20 }
}
<<< IntRow(){
$0.title = "Tage:"
$0.placeholder = "2"
$0.add(rule: RuleRequired())
}
.cellUpdate { cell, row in
cell.textField?.font = .boldSystemFont(ofSize: 18.0)
}
<<< KalkulationRow { row in
row.cell.valueField.text = "54.00"
}

根据vadian的建议,您可以使用onChange
方法检测文本更改,如下所示:
.onChange({ decimal in
print(decimal)
})
最终代码将是:
{
$0.header?.height = { 20 }
}
<<< DecimalRow(){
$0.title = " "
$0.tag = "MyRowTag"
}
.onChange({ decimal in
print(decimal)
})
.cellUpdate { cell, row in
cell.textField?.font = .boldSystemFont(ofSize: 18.0)
}
