试试下面的日期格式。

let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ssZZZ"
let date = dateFormatter. dateFromString (strDate)

希望能有所帮助。

Swift 4.1:

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ssZZZ"
let date = dateFormatter.date(from: strDate)

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)!

从iOS 15.0开始，我们可以更快速地将字符串转换为日期:

let strategy = Date.ParseStrategy(format: "\(year: .defaultDigits)-\(month: .twoDigits)-\(day: .twoDigits)T\(hour: .twoDigits(clock: .twentyFourHour, hourCycle: .zeroBased)):\(minute: .twoDigits):\(second: .twoDigits)\(timeZone: .iso8601(.short))", timeZone: .current)
let date = try? Date("2016-04-14T10:44:00+0000", strategy: strategy)

Swift 3.0 - 4.2

import Foundation

extension String {

    func toDate(withFormat format: String = "yyyy-MM-dd HH:mm:ss")-> Date?{

        let dateFormatter = DateFormatter()
        dateFormatter.timeZone = TimeZone(identifier: "Asia/Tehran")
        dateFormatter.locale = Locale(identifier: "fa-IR")
        dateFormatter.calendar = Calendar(identifier: .gregorian)
        dateFormatter.dateFormat = format
        let date = dateFormatter.date(from: self)

        return date

    }
}

extension Date {

    func toString(withFormat format: String = "EEEE ، d MMMM yyyy") -> String {

        let dateFormatter = DateFormatter()
        dateFormatter.locale = Locale(identifier: "fa-IR")
        dateFormatter.timeZone = TimeZone(identifier: "Asia/Tehran")
        dateFormatter.calendar = Calendar(identifier: .persian)
        dateFormatter.dateFormat = format
        let str = dateFormatter.string(from: self)

        return str
    }
}

只是 步骤1 > 从JSON或dataSource获取String值

步骤2 >创建本地变量并赋值。

let startDate = CurrentDashBoard.startdate

步骤3>创建DateFormatter实例。

let dateFormatter = DateFormatter()

步骤4 > 从dateFormatter调用dateFormat并提供保存的日期dataType。

dateFormatter.dateFormat = "MM-dd-yyyy HH:mm:ss"("may be String formate")

步骤5 > 将Local变量赋给要转换的变量。

let dateFromStringstartDate : NSDate = dateFormatter.date(from: startDate)! as NSDate

步骤6 > 请按以下代码填写所需日期。

dateFormatter.dateFormat = "MM/dd/yyyy HH:mm:ss"

步骤6>分配给label/text

cell.lblStartDate.text = String(format: "%@", strstartDate)

代码:

let startDate = CurrentDashBoard.startdate let dateFormatter = DateFormatter() 
dateFormatter.dateFormat = "MM-dd-yyyy HH:mm:ss" let dateFromStringstartDate : 
NSDate = dateFormatter.date(from: startDate)! as NSDate
dateFormatter.dateFormat = "MM/dd/yyyy HH:mm:ss"
let strstartDate = dateFormatter.string(from: dateFromStringstartDate as Date)

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!)
