嗨，你有单独的T格式，然后转换为你喜欢

// create dateFormatter with UTC time format
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
dateFormatter.timeZone = NSTimeZone(name: "UTC")
let date = dateFormatter.dateFromString("2015-04-01T11:42:00")

// change to a readable time format and change to local time zone
dateFormatter.dateFormat = "EEE, MMM d, yyyy - h:mm a"
dateFormatter.timeZone = NSTimeZone.localTimeZone() 
let timeStamp = dateFormatter.stringFromDate(date!)

Convert the ISO8601 string to date let isoDate = "2016-04-14T10:44:00+0000" let dateFormatter = DateFormatter() dateFormatter.locale = Locale(identifier: "en_US_POSIX") // set locale to reliable US_POSIX dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ" let date = dateFormatter.date(from:isoDate)! Get the date components for year, month, day and hour from the date let calendar = Calendar.current let components = calendar.dateComponents([.year, .month, .day, .hour], from: date) Finally create a new Date object and strip minutes and seconds let finalDate = calendar.date(from:components)

还可以考虑iOS 10 / macOS 10.12中引入的方便格式化程序ISO8601DateFormatter:

let isoDate = "2016-04-14T10:44:00+0000"

let dateFormatter = ISO8601DateFormatter()
let date = dateFormatter.date(from:isoDate)!

斯威夫特5。看是否一个日期已经通过:

let expiryDate = "2020-01-10" // Jan 10 2020

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"

if Date() < dateFormatter.date(from: expiryDate) ?? Date() {
    print("Not Yet expiryDate")
} else {
    print("expiryDate has passed")
}

我对这种格式也很着迷。

请参阅下面的解决方案。

你的字符串来自你的背部或其他来源:

    let isoDate = "2020-05-06 20:00:00-03"

识别日期格式

    let dateFormatter = DateFormatter()
    dateFormatter.locale = Locale(identifier: "en_US_POSIX")
    dateFormatter.dateFormat = "yyyy-MM-dd' 'HH:mm:ssZ"
    let date = dateFormatter.date(from:isoDate)!

现在您已经将日期设置为date()，您可以使用formatDate.string将其更改为您想要的任何格式

    let formatDate = DateFormatter()
    formatDate.dateFormat = "dd/MM/yyyy HH:mm"
    let drawDate = formatDate.string(from: date)
    print(drawDate)

输出:

    06/05/2020 20:00

那SwiftDate呢?Swift最好的日期和时间解析和操作库。

https://github.com/malcommac/SwiftDate#1-date-parsing

使用可可豆荚安装: https://github.com/malcommac/SwiftDate/blob/master/Documentation/0.Informations.md#installation

然后:

import SwiftDate

// All default datetime formats (15+) are recognized automatically
let _ = "2010-05-20 15:30:00".toDate()
// You can also provide your own format!
let _ = "2010-05-20 15:30".toDate("yyyy-MM-dd HH:mm")
// All ISO8601 variants are supported too with timezone parsing!
let _ = "2017-09-17T11:59:29+02:00".toISODate()
// RSS, Extended, HTTP, SQL, .NET and all the major variants are supported!
let _ = "19 Nov 2015 22:20:40 +0100".toRSS(alt: true)

创建全局函数

func convertDateFormat(inputDate: String) -> String {

     let olDateFormatter = DateFormatter()
     olDateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"

     let oldDate = olDateFormatter.date(from: inputDate)

     let convertDateFormatter = DateFormatter()
     convertDateFormatter.dateFormat = "MMM dd yyyy h:mm a"

     return convertDateFormatter.string(from: oldDate!)
}

调用函数并在其中传递值

get_OutputStr = convertDateFormat(inputDate: "2019-03-30T05:30:00+0000")

这里是输出
