Response to: a little improvement
Sorry to press the return by accident, let's continue: 1. Message can not contain colons: modify the criteria [msgComponents count] !=3 to [... count] <3 parse the message string: unsigned int hdLen = [(NSString *)[msgComponents ojectAtIndex: 0] length]; unsigned int nameLen = [... :1] length]; NSString *msgContents = [message substringFromIndex: hdLen + nameLen + 2*[@":" length]]; 2. the initWithCon... method statement: myName = [me copy]; I think should add a retain message: myName = [[me copy] retain]; 3. the last statement of method open...initiator should be: [chatWC showWindow: nil]; A typo.

Showing messages 1 through 1 of 1.

• a little improvement - another method for the colons

  Make sure you change the check on count as above.
  
  When we call postMessage:fromPerson in receiveMessage: we can change our call from:
  
  [self postMessage:[msgComponents objectAtIndex:2]
  fromPerson:[msgComponents objectAtIndex:1]];
  
  To:
  
  [self postMessage:[msgComponents [[subArrayWithRange: NSMakeRange(2, [msgComponents length] - 1)] componentsJoinedByString:@":"]] fromPerson:[msgComponents objectAtIndex:1]];
  
  Please double check brackets and that I've constructed that range properly. Granted, this doesn't make for easy reading, but it can be broken up over a couple of lines.
