1) please use the " <> " button above to post code.

2) you are posting lots of MCSession code and asking a question only about "notification tab" - and you are asking that question in the title of the post rather than in the post itself. Use the title as a title not a textfield. And what is "notification tab"?

3) assuming that your question relates to this line of code:

    [[NSNotificationCenter defaultCenter] postNotificationName:@"MCDidChangeStateNotification" object:nil userInfo:dict];

all you need to do to receive a notification is to add this line of code in any class in your project:

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(ReceivedSomeNotification:)
                                                 name:@"MCDidChangeStateNotification" object:nil];


// and then receive it here in the same class as the addObserver above:
-(void)ReceivedSomeNotification:(NSNotification *)notification{


}
