快速将Unix时间转换为日期和时间

为了使日期显示为当前时区，我使用了以下内容。

if let timeResult = (jsonResult["dt"] as? Double) {     let date = NSDate(timeIntervalSince1970: timeResult)     let dateFormatter = NSDateFormatter()     dateFormatter.timeStyle = NSDateFormatterStyle.MediumStyle //Set time style     dateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle //Set date style     dateFormatter.timeZone = NSTimeZone()     let localDate = dateFormatter.stringFromDate(date)}

Swift 3.0版本

if let timeResult = (jsonResult["dt"] as? Double) {    let date = Date(timeIntervalSince1970: timeResult)    let dateFormatter = DateFormatter()    dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style    dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style    dateFormatter.timeZone = self.timeZone    let localDate = dateFormatter.string(from: date)          }

斯威夫特5

if let timeResult = (jsonResult["dt"] as? Double) {    let date = Date(timeIntervalSince1970: timeResult)    let dateFormatter = DateFormatter()    dateFormatter.timeStyle = DateFormatter.Style.medium //Set time style    dateFormatter.dateStyle = DateFormatter.Style.medium //Set date style    dateFormatter.timeZone = .current    let localDate = dateFormatter.string(from: date)          }
