[英]How can I get added row textfield text when tapping button?
我在表視圖中為特定類別添加了額外的行,我需要在點擊按鈕時添加行文本字段 finalSearchValue。
我有兩個文本字段cell?.searchTextfield.text = alertParam
(這是從 json 獲取的手機號碼)和cell?.searchTextfield.text = "Amount"
(添加額外的行數量)如果我在這兩個文本字段中輸入文本,我需要那個兩個變量中的兩個值,在 payButton 中如何實現。
我采取了這樣的方式;
var cell : BillerTableViewCell?
var finalSearchValue : String = ""
var finalSearchValueAmnt : String = ""
如果我在 finalSearchValueAmnt 中輸入數量值,在 finalSearchValue 中輸入 phnum,我需要這兩個值,但我只得到最后一個文本字段值,為什么? 請幫忙。
這是代碼:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
cell = tableView.dequeueReusableCell(withIdentifier: "textfieldCell", for: indexPath) as? BillerTableViewCell
cell?.searchTextfield.delegate = self
if self.rowCount! - 1 >= indexPath.row
{
if let customerDetail = selectedBiller?.bcustomerparms[indexPath.row] {
alertParam = customerDetail.paramName
cell?.searchTextfield.text = alertParam
if var priceOfProduct: String = customerDetail.minLength {
alertMinL = Int(priceOfProduct)
}
if var priceOfProduct: String = customerDetail.maxLength {
alertMaxL = Int(priceOfProduct)
}
cell?.searchTextfield.addTarget(self, action: #selector(searchPhoneEditingChanged(textField:)), for: .editingChanged)
}
else{
print("no tf")
cell?.searchTextfield.text = "missing"
}
}
else{
cell?.searchTextfield.text = "Amount"
cell?.searchTextfield.addTarget(self, action: #selector(searchAmountEditingChanged(textField:)), for: .editingChanged)
}
}
return cell!
}
@objc func searchEditingChanged(textField: UITextField) {
finalSearchValue = textField.text!
self.textCount = self.finalSearchValue.count
}
@objc func buttonClicked(sender: UIButton) {
if self.finalSearchValue.isEmpty{
AlertFun.ShowAlert(title: "", message: "Please enter \(self.alertParam!)", in: self)
}
else if self.textCount ?? 0 < self.alertMinL ?? 0{
AlertFun.ShowAlert(title: "", message: "\(self.alertParam!) not lessthen \(self.alertMinL!)", in: self)
}
else if self.textCount ?? 0 > self.alertMaxL ?? 0{
AlertFun.ShowAlert(title: "", message: "\(self.alertParam!) not graterthen \(self.alertMaxL!)", in: self)
}
if self.finalSearchValueAmnt.isEmpty{
AlertFun.ShowAlert(title: "", message: "Please enter Amount", in: self)
}
else{
billerFetchService()
}
}
我怎樣才能在一個變量中獲得cell?.searchTextfield.text = "Amount"
finalSearchValue,請在上面的代碼中幫助我。
問題:如何從文本字段中獲取值。
解決方案:我創建了兩個操作方法。 第一個是電話號碼,第二個是金額。
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
cell = tableView.dequeueReusableCell(withIdentifier: "textfieldCell", for: indexPath) as? BillerTableViewCell
if self.rowCount! - 1 >= indexPath.row
{
if let customerDetail = selectedBiller?.bcustomerparms[indexPath.row] {
alertParam = customerDetail.paramName
cell?.searchTextfield.text = alertParam
cell?.searchTextfield.addTarget(self, action: #selector(searchPhoneEditingChanged(textField:)), for: .editingChanged) // for phone number
}
}
else{
cell?.searchTextfield.text = "Amount"
cell?.searchTextfield.addTarget(self, action: #selector(searchAmountEditingChanged(textField:)), for: .editingChanged) // for amount
}
}
return cell!
}
// 動作方法
@objc func searchPhoneEditingChanged(textField: UITextField) {
finalSearchValue = textField.text! // used to store phone Number
self.textCount = self.finalSearchValue.count
}
@objc func searchAmountEditingChanged(textField: UITextField) {
finalSearchValueAmnt = textField.text! // used to store Amount.
}
// 檢索兩個值
@objc func buttonClicked(sender: UIButton) {
//Now here you can get both the values.
print(finalSearchValueAmnt)
print(finalSearchValue)
}
