我收到一条错误验证消息。当我按下表单的重置按钮时就会显示出来。我认为是因为.validatesOnChange
但是,我不希望这样做,因为当我尝试提交表单时,验证本身可以正常工作。如果未输入任何内容,则消息弹出,如果用户输入内容,则消息消失。
在重置表单时,如何在不触发验证功能的情况下保持其功能?有没有更好的方法来重置我的表格?还是让我的验证消息显示和消失的更好方法?
@IBAction func resetButtonPressed(_ sender: UIBarButtonItem) {
form.setValues(["bmi": nil])
tableView.reloadData()
}
func createForm(){
LabelRow.defaultCellUpdate = { cell, row in
cell.contentView.backgroundColor = .red
cell.textLabel?.textColor = .white
cell.textLabel?.font = UIFont.boldSystemFont(ofSize: 13)
cell.textLabel?.textAlignment = .right
}
form +++ Section("Demographics")
<<< DecimalRow("bmi") {
$0.title = "BMI"
$0.placeholder = "40"
$0.useFormatterDuringInput = true
$0.add(rule: RuleRequired())
$0.validationOptions = .validatesOnChange
}
.onRowValidationChanged { cell, row in
let rowIndex = row.indexPath!.row
while row.section!.count > rowIndex + 1 && row.section?[rowIndex + 1] is LabelRow {
row.section?.remove(at: rowIndex + 1)
}
if !row.isValid {
for (index, validationMsg) in row.validationErrors.map({ $0.msg }).enumerated() {
let labelRow = LabelRow() {
$0.title = validationMsg
$0.cell.height = { 30 }
}
row.section?.insert(labelRow, at: row.indexPath!.row + index + 1)
}
}
}
答案 0 :(得分:0)
在行上添加RuleRequired时,在将nil值设置为该行之后,由于.ValidatesOnChange选项,您将收到验证错误。您可以这样做:
@IBAction func resetButtonPressed(_ sender: UIBarButtonItem) {
form.removeAll()
createForm()
}
