如何在 Swift 3 中将 unix 纪元时间转换为日期

Question

我想使用 Swift 3.

将从数据库中检索到的纪元时间（数字）转换为日期对象

我有以下号码代码

// e.g. 1475616846.424875
user.birthday.timeIntervalSince1970

如何在 Date 对象中转换它？

Answer 1

勾选 reference of Date:

init(timeIntervalSince1970: TimeInterval) 
Returns a Date initialized relative to 00:00:00 UTC on 1 January 1970 by a given number of seconds.

只需使用 Date:

的初始化器

let epochTime: TimeInterval = 1475616846.424875
let date = Date(timeIntervalSince1970: epochTime)
print(date) //->2016-10-04 21:34:06 +0000

Answer 2

SWIFT 3

此代码解决 swift 3.

的问题

func epochToLocal(epochTime:Double)->String{

    let timeResult:Double = epochTime
    let date = NSDate(timeIntervalSince1970: timeResult)
    let dateFormatter = DateFormatter()
    dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style
    dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style
    let timeZone = TimeZone.autoupdatingCurrent.identifier as String
    dateFormatter.timeZone = TimeZone(identifier: timeZone)
    let localDate = dateFormatter.string(from: date as Date)
    return "\(localDate)"

}
