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.

    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.
