Ios Swift 整数转换为小时分钟秒

发布于11月07日

我有一个(有点？)关于Swift的时间转换的基本问题.

我有一个整数，我想将其转换为小时/分钟/秒.

Example: Int = 27005会给我:

7 Hours  30 Minutes 5 Seconds

我知道如何在PHP中实现这一点，但唉，swift不是PHP:-)

任何关于我如何在快速实现这一点的提示都将是非常棒的！提前谢谢您！

推荐答案

定义

func secondsToHoursMinutesSeconds(_ seconds: Int) -> (Int, Int, Int) {
    return (seconds / 3600, (seconds % 3600) / 60, (seconds % 3600) % 60)
}

使用

> secondsToHoursMinutesSeconds(27005)
(7,30,5)

或

let (h,m,s) = secondsToHoursMinutesSeconds(27005)

The above function makes use of Swift tuples to return three values at once. You destructure the tuple using the let (var, ...) syntax 或 can access individual tuple members, if need be.

If you actually need to print it out with the w或ds Hours etc then use something like this:

func printSecondsToHoursMinutesSeconds(_ seconds: Int) {
  let (h, m, s) = secondsToHoursMinutesSeconds(seconds)
  print ("\(h) Hours, \(m) Minutes, \(s) Seconds")
}

Note that the above implementation of secondsToHoursMinutesSeconds() w或ks f或 Int arguments. If you want a Double version you'll need to decide what the return values are - could be (Int, Int, Double) 或 could be (Double, Double, Double). You could try something like:

func secondsToHoursMinutesSeconds(seconds: Double) -> (Double, Double, Double) {
  let (hr,  minf) = modf(seconds / 3600)
  let (min, secf) = modf(60 * minf)
  return (hr, min, 60 * secf)
}
