[ios] Swift 4 String, Date, DateFormatter 예제
조회 수 1519 댓글 0
Swift 4, Swift 3 에서 문자열을 Date() 읽고.
Date()를 DateFormatter로 문자열 출력하는 간단한 예제
1. Extensions 필요함
import Foundation
extension DateFormatter {
convenience init (format: String) {
self.init()
dateFormat = format
locale = Locale.current
}
}
extension String {
func toDate (format: String) -> Date? {
return DateFormatter(format: format).date(from: self)
}
func toDateString (inputFormat: String, outputFormat:String) -> String? {
if let date = toDate(format: inputFormat) {
return DateFormatter(format: outputFormat).string(from: date)
}
return nil
}
}
extension Date {
func toString (format:String) -> String? {
return DateFormatter(format: format).string(from: self)
}
}
2. 실행 예
var dateString = "14.01.2017T14:54:00"
let format = "dd.MM.yyyy'T'HH:mm:ss"
let date = Date()
print("original String with date: \(dateString)")
print("date String() to Date(): \(dateString.toDate(format: format)!)")
print("date String() to formated date String(): \(dateString.toDateString(inputFormat: format, outputFormat: "dd MMMM")!)")
print("format Date(): \(date.toString(format: "dd MMM HH:mm")!)")
