push notification in foreground

Question

I have an application with ability to receive Push Notifications.

When the application is in background mode push notification shows well, but if the application is in foreground mode I want to show my custom view with information from userInfo.

How can I notify any viewController from my appDelegate didReceiveRemoteNotification to show this custom view and send userInfo dictionary there?

Can someone help me with my problem?

Answer 1

You could send out a notification and then the viewControllers that you want to be alerted can have observers for them:

NSNotificationCenter.defaultCenter().postNotificationName("nameOfNotification", object: yourVariableContainingUserInfo)

Can you add observers like so:

NSNotificationCenter.defaultCenter().addObserver(self, selector: "nameOfNotification:", name: "nameOfNotification", object: nil)

And your selector would look something like this:

func nameOfNotification(notification: NSNotification) {
    if let dict = notification.object as? NSDictionary {
        //user your userInfo dictionary here
    }
}
