Just temporarily storing some code examples: <pre> <code> - (NSArray *)tokensSeparatedByCharactersFromSet:(NSCharacterSet *)separatorSet { NSScanner *scanner = [NSScanner scannerWithString:self]; NSCharacterSet *tokenSet = [separatorSet invertedSet]; NSMutableArray *tokens = [NSMutableArray array]; [scanner setCharactersToBeSkipped:separatorSet]; while (![scanner isAtEnd]) { NSString *destination = [NSString string]; if ([scanner scanCharactersFromSet:tokenSet intoString:&destination]) { [tokens addObject:[NSString stringWithString:destination]]; } } return [NSArray arrayWithArray:tokens]; } - (NSArray *)objCTokens { NSMutableCharacterSet *tokensSet = [NSMutableCharacterSet alphanumericCharacterSet]; [tokensSet addCharactersInString:@"_:"]; return [self tokensSeparatedByCharactersFromSet:[tokensSet invertedSet]]; } -(NSString *)removeTabsAndReturns { NSMutableString *outputString = [NSMutableString string]; NSCharacterSet *charSet; NSString *temp; NSScanner *scanner = [NSScanner scannerWithString:self]; charSet = [NSCharacterSet characterSetWithCharactersInString:@"\n\r\t"]; while ([scanner scanUpToCharactersFromSet:charSet intoString:&temp]) { [outputString appendString:temp]; } return [[outputString copy] autorelease]; } </pre> </code> |
