Tired of managing the NSObjectProtocol objects returned by NSNotificationCenter's addObserverForName()?
class MyHappyPlace: Observable /* It's a protocol */ {
func greeting() {
postNotificationName("Greeting") // <----- That was easy!
}
deinit {
removeObservers() // <----- Yes! indeed :)
}
}
class MyHappyObject: ObservableObserver /* It's also a protocol */ {
var myHappyPlace: MyHappyPlace
func do_something_awesome() {
myHappyPlace.addObserverForName("Greeting") { (note) in // <------ Now that's hot! (it's the Observable protocol)
print("Welcome!")
}
}
deinit {
stopObserving() // <------ Oooou nice one ;)~ this removes any observing from us
}
}- Observable
This protocol gives your class the addObserverForName() and removeObservers() methods for free (as well as postNotification() and postNotificationName() shortcut methods)
- ObservableObserver
This protocol gives your class the stopObserving() method for free
