有没有办法将自然语言日期NSString转换为NSDate [英] Is there a way to convert a natural language date NSString to an NSDate

问题描述

说我有NSString @明天

Say I have the NSString @"tomorrow"

是否有任何带有此类字符串的库并将它们转换为NSDates？我想象/希望这样的事情：

Is there any library that takes strings such as this and converts them into NSDates? I'm imagining/hoping for something like this:

NSString* humanDate = @"tomorrow at 4:15";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"x at HH:MM"];
NSDate* date = [dateFormatter dateFromString:humanDate];

我还想做下一个星期一等事情，但它没有要超级精致。我可以对输入执行规则，但我想要一些自然语言。

I would also want to do things like "Next monday", etc. but it doesn't have to be super sophisticated. I can enforce rules on input, but I'd like a little bit of natural language available.

我的选择是取字符串，将其分解成碎片，手动格式化。但我希望有人已经这样做了。

My alternative is to take the string, break it up into pieces, and format it manually. But I was hoping someone has already done this.

推荐答案

你的意思是像 dateWithNaturalLanguageString：？

从链接：

dateWithNaturalLanguageString：

dateWithNaturalLanguageString:

创建并返回一个NSDate对象，该对象设置为给定字符串指定的日期和时间。

Creates and returns an NSDate object set to the date and time specified by a given string.

+（id）dateWithNaturalLanguageString ：（NSString *）string

+ (id)dateWithNaturalLanguageString:(NSString *)string

包含日期口语规范的字符串，例如晚餐上周二，2001年12月31日下午3点， 12/31/01，或31/12/01。

A string that contains a colloquial specification of a date, such as "last Tuesday at dinner," "3pm December 31, 2001," "12/31/01," or "31/12/01."
