Spritekit - Keep the game paused when didBecomeActive

I have a pause system with a function and a button and it works perfect, i know when the app enters background it automatically pauses and when it comes back it automatically unpauses itself, my problem is that I don't know how to keep it paused when it becomes active again. 

func applicationWillResignActive(application: UIApplication) {

    NSNotificationCenter.defaultCenter().postNotificationName("Pause", object: nil) // tried here
}        


func applicationDidBecomeActive(application: UIApplication) {

    NSNotificationCenter.defaultCenter().postNotificationName("Pause", object: nil) // tried here
}

I tried on both those methods separately but the game keeps running, sometimes it shows my Pause menu (a layer above the gameplay) and still run in the background. So what is the correct way to achieve this ?

In your scene or view, you should be able to handle pause by adding an observer to it

    NSNotificationCenter.defaultCenter().addObserver(self,selector:Selector("pauseGame:",name:"Pause",object:nil)

Then you add a function to handle this

func pauseGame(notification:NSNotification)
{
    self.paused = true;
}

Now keep in mind I have found that in iOS 8 there is a bug where CBApplicationDidBecomeActive can cause undesirable results, so you need to override this in your SKView's class like this:

class GameSceneView : SKView
{
    ...//Other Code
    func CBApplicationDidBecomeActive()
    {
    }
}
