iOS Discussion Group 1 group: 135718460

1. Send a notification. (Take this notice as an example, notice the name: Gameovernotification. Notification Parameters: Title)

Nsnotificationcenter.defaultcenter (). Postnotificationname ("Gameovernotification", Object:title)

2. Add the Observer to the Viewdidload method to listen for this notification

      Nsnotificationcenter.defaultcenter (). Addobserver (Self, selector: "Gameover:", Name: "Gameovernotification", object: Nil

3. Implement the selector in 2. Method that the supervisor hears the notification call

Func Gameover (title:nsnotification)    {      var str = title.object as String        self.titleLable.text = str    }

Reminder: The number of parameters in the notification invocation method here must be nsnotification. Since we are sending 1 notices.

Friendly tip: in Swift. Assume that the logical structure of the project is not very clear generally with the notice.
