Swift：将ISO8601转换为Unix Epoch

Question

我想采用ISO8601时间戳，如下所示：YYYY-MM-DDTHH:MM:SSZ，并使用Swift将其转换为Unix纪元时间戳。

Answer 1

ISO8601DateFormatter将字符串转换为Date，timeIntervalSince1970获取UNIX时间戳。

let timestamp = ISO8601DateFormatter().date(from: "2017-07-14T20:00:00Z")!.timeIntervalSince1970

这是一个扩展

extension String{
func dateToEpoch() -> UInt64 {
    let isoFormatter = ISO8601DateFormatter()
isoFormatter.formatOptions = [.withFullDate,.withTime, .withFractionalSeconds,.withDashSeparatorInDate,.withColonSeparatorInTime]
let date = UInt64((isoFormatter.date(from: self)?.timeIntervalSince1970 ?? 0) * 1000)
    return date
}                                                               
}

使用

let epochTime =  "2021-04-14T10:09:10.773Z".dateToEpoch()
print(epochTime)

Answer 3

在搜索完所有 stackoverflow 之后，我可以创建一个工作片段！！

let isoFormatter = ISO8601DateFormatter()
    isoFormatter.formatOptions = [.withFullDate,.withTime, .withFractionalSeconds,.withDashSeparatorInDate,.withColonSeparatorInTime]
    let date = UInt64((isoFormatter.date(from: "2021-04-14T10:09:10.773Z")?.timeIntervalSince1970 ?? 0) * 1000) // your time here with milliseconds
print(date) // prints 1619706315298
