大家好
小弟最近在家看書自學Swift
在練習操作datepicker元件時
想讓顯示的訊息 隨著選取時間而更動內容
卻完全沒有動靜 只顯示起始時間
想請問下面程式碼有哪裡是有問題的嗎？
import UIKit
class ViewController: UIViewController {
var dateFormatter = NSDateFormatter()
@IBOutlet var datePicker: UIDatePicker!
@IBOutlet var labelMsg: UILabel!
@IBAction func dateChange(sender: UIDatePicker) {
labelMsg.text = dateFormatter.stringFromDate(datePicker.date)
}
override func viewDidLoad() {
super.viewDidLoad()
datePicker.datePickerMode = UIDatePickerMode.DateAndTime
datePicker.locale = NSLocale(localeIdentifier: "zh_TW")
datePicker.date = NSDate()
dateFormatter.dateFormat = "西元y年MM月dd日hh時mm分ss秒"
labelMsg.text = dateFormatter.stringFromDate(datePicker.date)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
感謝大家！！！
