转换日期字符串swift [英] Convert date string swift

问题描述

我有这种格式的日期字符串：

I have a date string in this format:

2016-06-20T13:01:46.457+02:00

我需要将其更改为：

20/06/2016

以前我有总是使用这个库 - > SwiftDate 来操纵日期，但是它现在不起作用。

Previously I have always used this library -> SwiftDate to manipulate the dates, but it doesn't work now.

我也尝试了类似的东西：

I tried also something like:

let myDate = self.dateNoteDict[indexPath.row]!
    let dateFormatter = NSDateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss.SSSSxxx"
    let date = dateFormatter.dateFromString(myDate)
    print("date -> \(date)")

但不起作用。我该怎么办？

but it doesn't work. How can I do?

提前致谢。

推荐答案

标准ISO8601日期格式，小数秒和时区是

The standard ISO8601 date format with fractional seconds and time zone is

yyyy-MM-dd'T'HH：mm：ss.SSSZ

yyyy-MM-dd'T'HH:mm:ss.SSSZ

let myDate = "2016-06-20T13:01:46.457+02:00"
let dateFormatter = NSDateFormatter()
dateFormatter.locale = NSLocale(localeIdentifier: "en_US_POSIX") // edited
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let date = dateFormatter.dateFromString(myDate)!
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateString = dateFormatter.stringFromDate(date)

Swift 3：

let myDate = "2016-06-20T13:01:46.457+02:00"
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX") // edited
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let date = dateFormatter.date(from:myDate)!
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateString = dateFormatter.string(from:date)
