【问题描述】：

我正在使用 swift 在 Xcode 中创建一个应用程序，并且我有一个使用 UIDatePicker 的文本框，但是现在我的所有其他文本框都在使用这个日期选择器，而我希望它们只是一个数字键盘。任何帮助深表感谢。我想成为 UIDatePicker 的文本框称为“StartDate”，但我还有其他需要成为数字键盘的文本框。我仍然是 Swift 和 XCode 的初学者，但就像我说的，非常感谢所有帮助。

import UIKit
import EventKit

class ViewController: UIViewController, UITextFieldDelegate 

weak var StartDate: UITextField!

func textFieldDidBeginEditing(textField: UITextField) 
    let datePicker = UIDatePicker()
    textField.inputView = datePicker
    datePicker.datePickerMode = UIDatePickerMode.Date

    datePicker.addTarget(self, action: "datePickerChanged:", forControlEvents: .ValueChanged)


func datePickerChanged(sender: UIDatePicker) 
    let formatter = NSDateFormatter()
    formatter.dateStyle = .LongStyle
    StartDate.text = formatter.stringFromDate(sender.date)


func textFieldShouldReturn(textField: UITextField) -> Bool 
    textField.resignFirstResponder()
    return true


// Code to close keyboard that can be used throughout the app
func closeKeyboard() 
    self.view.endEditing(true)


// Close keyboard on touch anywhere else
  override func touchesBegan(touches: NSSet, withEvent event: UIEvent) 
    closeKeyboard()


 override func viewDidLoad() 
    super.viewDidLoad()
    StartDate.delegate = self


 override func didReceiveMemoryWarning() 
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.

【参考方案1】：

试试这样的：

func textFieldDidBeginEditing(textField: UITextField) 
    if textField == StartDate 
        let datePicker = UIDatePicker()
        textField.inputView = datePicker
        datePicker.datePickerMode = UIDatePickerMode.Date

        datePicker.addTarget(self, action: "datePickerChanged:", forControlEvents: .ValueChanged)
    else 
        //do stuff with the rest of the textFields
