Question

我有两个单独的文本字段，它们都使用日期选择器来选择日期，但是，当我编辑日期时，两者都显示相同的日期。如何将两者分开，以便每个人都有自己的日期选择器？

@IBOutlet weak var dateField1: UITextField!
@IBOutlet weak var dateField2: UITextField!
let dateFormat: NSDateFormatter = NSDateFormatter()
let datePicker: UIDatePicker = UIDatePicker()
let dateFormat2: NSDateFormatter = NSDateFormatter()
let datePicker2: UIDatePicker = UIDatePicker()

override func viewDidLoad() {
    super.viewDidLoad()
    dateFormat.dateStyle = NSDateFormatterStyle.ShortStyle
    dateFormat.timeStyle = NSDateFormatterStyle.ShortStyle
    datePicker.datePickerMode = UIDatePickerMode.DateAndTime
    datePicker.addTarget(self, action: Selector("updateDateField:"), forControlEvents:UIControlEvents.ValueChanged)
    dateField.inputView = datePicker
    dateFormat2.dateStyle = NSDateFormatterStyle.ShortStyle
    dateFormat2.timeStyle = NSDateFormatterStyle.ShortStyle
    datePicker2.datePickerMode = UIDatePickerMode.DateAndTime
    datePicker2.addTarget(self, action: Selector("updateDateField:"), forControlEvents:UIControlEvents.ValueChanged)
    delivery.inputView = datePicker2

    // Do any additional setup after loading the view.
}

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    self.navigationController?.toolbarHidden = false
    self.tabBarController?.tabBar.hidden = true
}

func updateDateField(sender: UIDatePicker) {
    dateField.text = dateFormat.stringFromDate(sender.date)
    delivery.text = dateFormat2.stringFromDate(sender.date)


}

请检查以下代码 -

func updateDateField(sender: UIDatePicker) {
   if sender == datePicker
   {
    dateField.text = dateFormat.stringFromDate(sender.date)
   }
   if sender == datePicker2
   {
    delivery.text = dateFormat2.stringFromDate(sender.date)
   }


}

在IOS中使用DatePicker而不是键盘的两个单独的文本字段
