如何快速将日期和时间分别发送到后端？

如何解决如何快速将日期和时间分别发送到后端？

fromDateLabel.text从datepicker获取日期和时间。我需要将日期和时间分别发送到后端

当我正确执行DateFormatter日期但我 n时间时，只有两位数字有效，这意味着时间需要10、11、12点。如果我认为1,2,3,4,5不起作用

代码：此处单位时间无效

    var fromDateArr = fromDateLabel.text!.components(separatedBy: ",")
    fromDate = fromDateArr[0]
    fromTime = fromDateArr[1].replacingOccurrences(of: " ",with: "")

        let inputFormatter = DateFormatter()
        inputFormatter.dateFormat = "MM/dd/yy"
        let showDateFrom = inputFormatter.date(from: fromDate)
        inputFormatter.dateFormat = "dd-MM-yyyy"
        formateFromdate = inputFormatter.string(from: showDateFrom!)
        print("formate from date \(formateFromdate)")

如果我像下面这样安排日期和时间，则无济于事

        let fromDate = fromDateLabel.text!
        let inputFormatter = DateFormatter()
        inputFormatter.dateFormat = "MM/dd/yy,hh:mm:ssa"
        guard  let showDateFrom = inputFormatter.date(from: fromDate) else { return }

        inputFormatter.dateFormat = "MM/dd/yyyy" // -> to get date only
        formateFromdate = inputFormatter.string(from: showDateFrom)
        print("from date: ",formateFromdate)

        inputFormatter.dateFormat = "hh:mm a" // -> to get time only
        formateFromTime = inputFormatter.string(from: showDateFrom)

        print("from time")

如何将日期和时间分别发送到后端.. 1到12小时时间

注意：如果是8点钟，那么输出时间应该是08:15，而不是8:15。这就是问题所在。请帮助我提供代码

设计

import UIKit

class ViewController: UIViewController{

    @IBOutlet weak var txtdate: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        self.txtdate.setInputViewDatePicker(target: self,selector: #selector(tapDone)) //1
    }

    @objc func tapDone() {
        if let datePicker = self.txtdate.inputView as? UIDatePicker {
            let dateformatter = DateFormatter()
            dateformatter.dateFormat = "MM/dd/yy,hh:mm a"
            self.txtdate.text = dateformatter.string(from: datePicker.date)
        }
        self.txtdate.resignFirstResponder()
    }

    @IBAction func showClk(_ sender: Any) {
        let fromDate = txtdate.text!
        print(fromDate)
        let inputFormatter = DateFormatter()
        inputFormatter.dateFormat = "MM/dd/yy,hh:mm a"
        guard  let showDateFrom = inputFormatter.date(from: fromDate) else { return }

        inputFormatter.dateFormat = "MM/dd/yyyy" // -> to get date only
        let formateFromdate = inputFormatter.string(from: showDateFrom)
        print("from date: ",formateFromdate)

        inputFormatter.dateFormat = "hh:mm a" // -> to get time only
        let formateFromTime = inputFormatter.string(from: showDateFrom)

        print("from time",formateFromTime)
    }
}

extension UITextField {

    func setInputViewDatePicker(target: Any,selector: Selector) {
        // Create a UIDatePicker object and assign to inputView
        let screenWidth = UIScreen.main.bounds.width
        let datePicker = UIDatePicker(frame: CGRect(x: 0,y: 0,width: screenWidth,height: 216))//1
        datePicker.datePickerMode = .date
        self.inputView = datePicker
    
        // Create a toolbar and assign it to inputAccessoryView
        let toolBar = UIToolbar(frame: CGRect(x: 0.0,y: 0.0,height: 44.0))
        let flexible = UIBarButtonItem(barButtonSystemItem: .flexibleSpace,target: nil,action: nil)
        let cancel = UIBarButtonItem(title: "Cancel",style: .plain,action: #selector(tapCancel))
        let barButton = UIBarButtonItem(title: "Done",target: target,action: selector)
        toolBar.setItems([cancel,flexible,barButton],animated: false)
        self.inputAccessoryView = toolBar
    }

    @objc func tapCancel() {
        self.resignFirstResponder()
    }
}
