DatePicker, TimePicker

 

• 시작일시, 종료일시  각각의 TextField Form이  있을것
• 터치시  datePicker or timePicker 가 keyboard 대신 올라올것
  
  • IiOS 13.4 부터 UIPickerView 스타일이 다양 해짐
    

    @available(iOS 13.4, *)

    public enum UIDatePickerStyle : Int, @unchecked Sendable {

     

        

        /// Automatically pick the best style available for the current platform & mode.

        case automatic = 0

     

        /// Use the wheels (UIPickerView) style. Editing occurs inline.

        case wheels = 1 // 휠밖에 모르던시절 

     

        /// Use a compact style for the date picker. Editing occurs in an overlay.

        case compact = 2 // 원하는 날짜 선택하는 맛이 없음

     

        /// Use a style for the date picker that allows editing in place.

        @available(iOS 14.0, *)

        case inline = 3 // 원하는 날짜를 선택하고 싶어서 차용
