iOS上的NSDate的人性化日期描述 [英] Human friendly date descriptions with NSDate on iOS

问题描述

我想以人性化的方式显示NSDates，例如上周或几天前。类似于 Java的美好时光。

I want to display NSDates in a "human-friendly way", such as "last week", or "a few days ago". Something similar to Pretty Time for Java.

什么是最好的办法这，子类NSDateFormatter？

What's the best way to do this, subclassing NSDateFormatter? Before I go and reinvent the wheel, is there already some library for this?

推荐答案

这是Swift 2中的解决方案：

This is the solution in Swift 2:

func formattedHumanReadable(date: NSDate) -> String {
    let formatter = NSDateFormatter()
    formatter.timeStyle = .NoStyle
    formatter.dateStyle = .ShortStyle
    formatter.doesRelativeDateFormatting = true

    let locale = NSLocale.currentLocale()
    formatter.locale = locale

    return formatter.stringFromDate(date)
  }
