Hi out there, I found two small things that seems to need some improvement: 1) If the message to be sent contains a ":" the message is not handled correctly by the receiver. It is just skipped as it does not have 3 but 4 ":" 2) If the "login name" contains a non ascii character, for example a ö, the message is not transmitted correctly. The last character is missing. Greetings Peter

Showing messages 1 through 1 of 1.

  the second problem is caused by the [message length] statement in sendMessage method is return the character's number by Unicode encoding.
  
  For example, if you have a string contains 1 chinese character, [message length] will return 1; but this string might be 4 bytes long.
  
  our dataWithBytes:length method of NSData need the real length of the string in bytes. So, this results in sending the string imcompletely.
  
  what we should do is use the strlen of C instead:
  
  NSData *message=[[NSData dataWithBytes:[message UTF8String] length: strlen([message UTF8String])];
