Modes

UIDatePicker has various picker modes.

enum UIDatePickerMode : Int {
    case Time
    case Date
    case DateAndTime
    case CountDownTimer
}

• Time - The date picker displays hours, minutes, and (optionally) an AM/PM designation.
• Date - The date picker displays months, days of the month, and years.
• DateAndTime - The date picker displays dates (as unified day of the week, month, and day of the month values) plus hours, minutes, and (optionally) an AM/PM designation.
• CountDownTimer - The date picker displays hour and minute values, for example [ 1 | 53 ]. The application must set a timer to fire at the proper interval and set the date picker as the seconds tick down.
