时间戳和字符串之间转换 Swift Swift

//时间戳转成字符串 func timeIntervalChangeToTimeStr(timeInterval:TimeInterval, dateFormat:String?) -> String { let date:NSDate = NSDate.init(timeIntervalSince1970: timeInterval/1000) let formatter = DateFormatter.init() if dateFormat == nil { formatter.dateFormat = "yyyy-MM-dd HH:mm:ss" }else{ formatter.dateFormat = dateFormat } return formatter.string(from: date as Date) }

//字符串转时间戳 func timeStrChangeTotimeInterval(timeStr: String?, dateFormat:String?) -> String { if timeStr?.count ?? 0 > 0 { return "" } let format = DateFormatter.init() format.dateStyle = .medium format.timeStyle = .short if dateFormat == nil { format.dateFormat = "yyyy-MM-dd HH:mm:ss" }else{ format.dateFormat = dateFormat } let date = format.date(from: timeStr!) return String(date!.timeIntervalSince1970) }
