Kugel

A glorious Swift wrapper around NSNotificationCenter.

⚠️ Deprecated ⚠️

This library is deprecated and will not be maintained anymore.

With Swift 3, working with NotificationCenter is more concise so we recommend using NotificationCenter.default directly.

The only feature that Kugel had over using NotificationCenter was to subscribe to multiple events at once using a notification name => selector map, but this can be easily implemented in your own code using the following extension:

extension NotificationCenter {
    func addObserver(_ observer: Any, _ namesAndSelectors: [NSNotification.Name: Selector], object: Any? = nil) {
        for (name, selector) in namesAndSelectors {
            addObserver(observer, selector: selector, name: name, object: object)
        }
    }
    func removeObserver(_ observer: Any, names: [NSNotification.Name], object: Any? = nil) {
        for name in names {
            removeObserver(observer, name: name, object: object)
        }
    }
}

Install

Usage

Publish

Kugel.publish("NotificationName")
Kugel.publish("NotificationName", object: anObject)
Kugel.publish("NotificationName", userInfo: ["foo": "bar"])
Kugel.publish("NotificationName", object: anObject, userInfo: ["foo": "bar"])
Kugel.publish(NSNotification(name: "NotificationName"))

Subscribe

let token = Kugel.subscribe("NotificationName") { notification in }

Kugel.subscribe(self, name: "NotificationName", selector: "onNotificationReceived:")

Kugel.subscribe(self, name: "NotificationName", selector: "onNotificationReceived:", object: object)

Kugel.subscribe(self, [
    "NotificationName1": "onNotification1Received:",
    "NotificationName2": "onNotification2Received:",
])

Kugel.subscribe(self, [
    "NotificationName1": "onNotification1Received:",
    "NotificationName2": "onNotification2Received:",
], object: object)

Unsubscribe

Kugel.unsubscribe(token)

Kugel.unsubscribe(self, name: "NotificationName")

Kugel.unsubscribe(self, name: "NotificationName", object: object)

Kugel.unsubscribe(self, [
	"NotificationName1",
	"NotificationName2"
])

Kugel.unsubscribe(self, [
	"NotificationName1",
	"NotificationName2"
], object: object)

Kugel.unsubscribe(self)
