Swift NSNotificationCenter does not fire

Question

I have some problems with swift and the NSNotificationCenter-System. I added the Observer like that:

NSNotificationCenter.defaultCenter().addObserverForName("disconnected", object: nil, queue: nil) { note in
        self.btConnect.title = "Verbinden"
}

and I posted a notification like this:

NSNotificationCenter.defaultCenter().postNotificationName("disconnect", object: self)

But Nothing happens. the Observer and the Notifier are in differentness classes. Can someone help me, what I'm doing wrong?

Answer 1

您的通知名称不正确：“已断开连接”与“断开连接”。

Answer 2

Your both methods need to have the same name. Currently they are disconnected and disconnect . You have to change the postNotificationName parameter from:

NSNotificationCenter.defaultCenter().postNotificationName("disconnect", object: self)

To:

NSNotificationCenter.defaultCenter().postNotificationName("disconnected", object: self)
