使用各种格式将时间戳转换为日期 [英] Convert Timestamp to Date with various formats Swift

问题描述

代码：-

let addedTime = dictMessage?.object(forKey: "added_time") as? String
let timeinterval : TimeInterval = (addedTime as NSString).doubleValu                
let dateFromServer = NSDate(timeIntervalSince1970:timeinterval)
let dateFormater : DateFormatter = DateFormatter()              
dateFormater.dateFormat = "dd-MMM-yyyy hh:mm a"
cellDetailsShop.lblTimeShop?.text = dateFormater.string(from: dateFromServer as Date)

我有一个json，并且从json im获得 Timestamp ，我已经将其转换为Date.Date，我收到它的日期显示在格式 dd-MMM-yyyy hh：mm a 。但是我想显示日期，例如date是今天，那么它将显示：今天04:55 PM ，如果日期是昨天，那么我将显示为：昨天5 PM ，如果在此之前它应显示为i正在从JSON检索。我搜索了各种链接，但找不到答案。有人可以帮助我。谢谢。

推荐答案

从Calendar对象开始，您可以获取日期是今天还是昨天。
基于此，您可以根据需要设置String。
我创建了一个您需要的示例。下面的
是代码。

As from Calendar object you can get if the date is today or yesterday. based on that you can set String as you like. I've created an example like you need. below is code.

var yesterdayStr = "17-Jan-2018 10:23 AM"
var todayStr = "18-Jan-2018 10:23 AM"
var tomorrowStr = "19-Jan-2018 10:23 AM"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MMM-yyyy hh:mm a"
let yesterDaydate = dateFormatter.date(from: yesterdayStr)
let todayDate = dateFormatter.date(from: todayStr)
let tomorrowDate = dateFormatter.date(from: tomorrowStr)
let anotherDateFormatter = DateFormatter()
anotherDateFormatter.dateFormat = "hh:mm a"
if Calendar.current.isDateInYesterday(yesterDaydate!)
{
    let yesterdayDisplayString = "Yesterday, " + anotherDateFormatter.string(from: yesterDaydate!)
}
if Calendar.current.isDateInToday(todayDate!) {
    let todayDisplayString = "Today, " + anotherDateFormatter.string(from: todayDate!)
}
if Calendar.current.isDateInToday(tomorrowDate!) {

}
else {
    let anotherDisplayString = anotherDateFormatter.string(from: tomorrowDate!)
}

这是输出，
