推荐答案

你说:

我的代码当前以分钟为单位显示某物的年龄，例如 4503mint .我希望能够以下列格式显示这些值 3 days 3 hours 3 mint 而不是 4503 mint.

My code currently displaying the age of something in minutes e.g 4503mint . I want to be able to display these values in the following format 3 days 3 hours 3 mint rather than 4503 mint.

您可以使用 NSDateComponentsFormatter 对其进行格式化.只需将分钟数乘以 60 即可获得 NSTimeInterval，然后您就可以将其提供给格式化程序:

You can format this using NSDateComponentsFormatter. Just multiply the number of minutes by 60 to get the NSTimeInterval, and then you can supply that to the formatter:

let formatter = NSDateComponentsFormatter()
formatter.unitsStyle = .Full

let minutes = 4503
let timeInterval = NSTimeInterval(minutes * 60)
print(formatter.stringFromTimeInterval(timeInterval))

这将产生3 天 3 小时 3 分钟"(或任何适合该设备语言环境的格式).

That will produce "3 days, 3 hours, 3 minutes" (or in whatever format appropriate for the locale for that device).

请参阅 NSDateComponentsFormatter 参考更多信息.
