廢話沒有，直接看代碼

  extension NSDate {
//對時間的處理
//傳入的時間戳精確到毫秒
    public  class func created_at(date:Double)->String{
    
    let myDate = NSDate.init(timeIntervalSince1970: date / 1000 )
    
    let fmt  = DateFormatter()
    fmt.dateFormat = "yyyy-MM-dd HH:mm:ss"
    fmt.locale = NSLocale(localeIdentifier: "en_US") as Locale?
    //獲得當前時間
    let now = NSDate()
    //計算時間差
    let interval = now.timeIntervalSince(myDate as Date)
    // 處理小于一分鐘的時間
    if interval < 60 {
        return "剛剛"
    }
    // 處理小于一小時的時間
    if interval < 60 * 60 {
        return "\(interval / 60)分鐘前"
    }
    // 處理小于一天的時間
    if interval < 60 * 60 * 24 {
        return "\(interval / (60 * 60))小時前"
    }
     // 處理昨天時間
    let calendar = Calendar.current
    if calendar.isDateInYesterday(myDate as Date) {
        fmt.dateFormat = "昨天 HH:mm"
        let timeStr  = fmt.string(from: myDate as Date)
        return timeStr
    }
   //處理一年之內的時間
    let cmp  = calendar.dateComponents([.year,.month,.day], from: myDate as Date, to: now as Date)
    if cmp.year! < 1 {
        fmt.dateFormat = "MM-dd HH:mm"
        let timeStr  = fmt.string(from: myDate as Date)
        return timeStr
    }
    //超過一年的時間
    fmt.dateFormat = "yyyy-MM-dd HH:mm"
    let timeStr = fmt.string(from: myDate as Date)
    return timeStr
 }

}

注意需要精確到毫秒的時間戳哦，復制這段代碼去試試吧????????????
