Getting Started

import JSQNotificationObserverKit

Example

// Suppose we have a UIView that posts a notification when its size changesletmyView=UIView()// This notification posts a CGSize value from a UIView senderletnotification=Notification<CGSize,UIView>(name:"NewViewSizeNotif", sender: myView)// This observer listens for the notification described abovevarobserver:NotificationObserver<CGSize,UIView>?// Register observer, start listening for the notificationobserver=NotificationObserver(notification){(value, sender)in    // handle notification    // the value and sender are both passed here}// Post the notification with the updated CGSize valuenotification.post(CGSizeMake(200,200))// Unregister observer, stop listening for notificationsobserver=nil

Notifications without a sender

// This notification posts a string value, the sender is nilletnotification=Notification<String,AnyObject>(name:"StringNotif")// Post the notificationnotification.post("new string")// Register observer, this handles notifications from *any* sendervarobserver:NotificationObserver<String,AnyObject>?observer=NotificationObserver(notification){(value, sender)in    // handle notification    // the value is passed here, sender is nil}// unregister observer, stop listening for notificationsobserver=nil

Using a custom queue and notification center

// Initialize an observer and post a notification// with a custom notification center and operation queueletc=NSNotificationCenter.defaultCenter()letq=NSOperationQueue.mainQueue()letobserver=NotificationObserver(n, queue: q, center: c){(value, sender)in    // handle notification}notification.post(v, center: c)

Notifications without a value

letnotification=Notification<Any?,AnyObject>(name:"MyEventNotification")letobserver=NotificationObserver(notification){(value, sender)in    // handle notification    // value is nil, sender is nil}// notification value is `Any?`, so pass nilnotification.post(nil)

Working with "traditional" Cocoa notifications

letnotification=CocoaNotification(name: UIApplicationDidReceiveMemoryWarningNotification)letobserver=CocoaObserver(notification, handler:{(notification:NSNotification)in    // handle the notification})// the notification will be posted by iOS
