A category to extend Cocoa's NSDate class with relative date function
To use it in your Cocoa project, import the header and implementation files, and then add the header to your project’s _prefix.pch file so that it’s available across your project:
#ifdef __OBJC__ #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> #import "NSDate+RelativeDate.h" #endif
And in your source:
NSDate *date = [NSDate date]; NSString *relativeDate = [date relativeDate];
The output format is relativeNumber+firstCharOfTheDateUnit, such as "now", "1s" (one second ago), "2d" (two days ago), "3w" (three weeks ago), "4m" (four months ago), "5y" (five years ago), etc.
