A set of regular expression classes for Objective-C. This framework is built off of the PCRE library (6.7). Here are the basics:
#import <ObjCRegex/ObjCRegex.h>
// create a regex for multiple uses
PCRegex *regex = [PCRegex regexWithPattern:@"pattern"];
// match the regex
[@"This is the string that I want to match" match:regex];
[@"This string will match because it contains the word pattern" match:regex];
// matching without creating a regex object
[@"This is the string that I want to match" matchPattern:@"pattern"];
[@"This is the string that I want to match" matchPattern:@"str.*"];
// matching with backreferences
NSArray *backrefArray;
PCRegex *regex = [PCRegex regexWithPattern:@"([^ ]*) ([^ ]*)"];
[@"first second third" match:regex backreferences:backrefArray];
NSString *first_match = [[backrefArray objectAtIndex:1] string];
NSString *second_match = [[backrefArray objectAtIndex:2] string];
