RegexKitLite's arrayOfCaptureComponentsMatchedByRegex: written using NSRegularExpression

gistfile1.m

// I had a need to replace the use of RegexKitLite's arrayOfCaptureComponentsMatchedByRegex with
// the built-in NSRegularExpression in iOS 5+, and didn't find an existing example, so I wrote one:

- (NSArray *) arrayOfCaptureComponentsOfString:(NSString *)data matchedByRegex:(NSString *)regex
{
    NSError *error = NULL;
    NSRegularExpression *regExpression = [NSRegularExpression regularExpressionWithPattern:regex options:NSRegularExpressionCaseInsensitive error:&error];
    
    NSMutableArray *test = [NSMutableArray array];
    
    NSArray *matches = [regExpression matchesInString:data options:NSRegularExpressionSearch range:NSMakeRange(0, data.length)];
    
    for(NSTextCheckingResult *match in matches) {
        NSMutableArray *result = [NSMutableArray arrayWithCapacity:match.numberOfRanges];
        for(NSInteger i=0; i<match.numberOfRanges; i++) {
            NSRange matchRange = [match rangeAtIndex:i];
            NSString *matchStr = nil;
            if(matchRange.location != NSNotFound) {
                matchStr = [data substringWithRange:matchRange];
            } else {
                matchStr = @"";
            }
            [result addObject:matchStr];
        }
        [test addObject:result];
    }
    return test;
}

Thanks for the code! Worked like a charm! :D
