Question

enter image description here我需要创建启用用户交互的按钮或标签。我们可以创建它吗？我试图在用户点击文本字段之外时禁用文本字段。但是无法完成它。

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
{
let currentCellDescriptor = getCellDescriptorForIndexPath(indexPath)
                let cell:ArrowCell = tableView.dequeueReusableCell(withIdentifier: "\(idString)") as! ArrowCell
                cell.currentMinimumValueTextField.delegate = self
                cell.currentaximumvaluextield.delegate = self

     cell.currentMinimumValueTextField.isEnabled = false
                cell.currentaximumvaluextield.isEnabled = false
}

 func textFieldDidBeginEditing(_ textField: UITextField) {
        textField.isEnabled = true
        print("TextField did begin editing method called")

    }
    func textFieldDidEndEditing(_ textField: UITextField) {
        print("TextField did end editing method called\(textField.text!)")
    }

    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        textField.resignFirstResponder();
        return true;
    }

提前致谢

感谢您的回复。我找到了一个使用textfield delegates的解决方案。在文本字段外面单击我正在禁用textfields.With这个方法我可以编辑并在textfields中显示滑块值。

func textFieldDidEndEditing(_ textField: UITextField)
{

    if (textField.tag == 1){
        let min = textField.text
        print(min)
        appDelegate.updatedsliderprice = true
        appDelegate.pricesliderlowerValue = Double(min!)!
    }
    else
   {
       let max = textField.text
        print(max)
    appDelegate.updatedsliderprice = true
    appDelegate.pricesliderupperValue = Double(max!)!
   }
    rangeSliderValueChanged(RangeSliderValue: rangeSlider)
    tableView.reloadSections(IndexSet(integer: 2), with: UITableViewRowAnimation.fade)
}
