Say I have the NSString @"tomorrow"
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];
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.
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.
回答1:
Do you mean something like dateWithNaturalLanguageString:?
From the link:
dateWithNaturalLanguageString:
Creates and returns an NSDate object set to the date and time specified by a given string.
+ (id)dateWithNaturalLanguageString:(NSString *)string
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.”
