Swift 对时间的显示样式处理(朋友圈、微博发布时间)

显示时间需求.jpg

废话没有，直接看代码

  extension NSDate {
//对时间的处理
//传入的时间戳精确到毫秒
    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?
    //获得当前时间
    let now = NSDate()
    //计算时间差
    let interval = now.timeIntervalSince(myDate as Date)
    // 处理小于一分钟的时间
    if interval < 60 {
        return "刚刚"
    }
    // 处理小于一小时的时间
    if interval < 60 * 60 {
        return "\(interval / 60)分钟前"
    }
    // 处理小于一天的时间
    if interval < 60 * 60 * 24 {
        return "\(interval / (60 * 60))小时前"
    }
     // 处理昨天时间
    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
    }
   //处理一年之内的时间
    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
    }
    //超过一年的时间
    fmt.dateFormat = "yyyy-MM-dd HH:mm"
    let timeStr = fmt.string(from: myDate as Date)
    return timeStr
 }

}

注意需要精确到毫秒的时间戳哦，复制这段代码去试试吧🙂🙂🙂🙂🙂🙂
