Nodes cannot be pressed after camera moves with nodes - swift

Question

I was able to make my control buttons move with the camera, however after the player moves they no longer work. I thought their location moves with the node, so that in touches began the location would still work when being touched. Should I also update the location after the player has stopped moving? The camera node moves with the player.
override func didMove(to view: SKView) {
self.anchorPoint = CGPoint(x: 0.5, y: 0.5)
// Make sure you can get teh player from the scene file
if let somePlayer = self.childNode(withName: "player") as? SKSpriteNode {
player = somePlayer
// Set physics
player.physicsBody?.isDynamic = false
} else {
print("No player")
}
let widthHalf:CGFloat = self.view!.bounds.width / 2
let heightHalf:CGFloat = self.view!.bounds.height / 2
cameraNode.addChild(buttonNorth)
buttonNorth.position = CGPoint(x: -widthHalf + 80, y: -heightHalf + 100)
cameraNode.addChild(buttonSouth)
buttonSouth.position = CGPoint(x: -widthHalf + 80, y: -heightHalf + 40)
buttonSouth.yScale = -1
cameraNode.addChild(buttonWest)
buttonWest.position = CGPoint( x: -widthHalf + 30, y: -heightHalf + 70)
cameraNode.addChild(buttonEast)
buttonEast.position = CGPoint( x: -widthHalf + 130, y: -heightHalf + 70)
buttonNorth.xScale = 0.4
buttonNorth.yScale = 0.4
buttonSouth.xScale = 0.4
buttonSouth.yScale = 0.4
buttonSouth.zRotation = CGFloat(Double.pi)
buttonEast.xScale = 0.4
buttonEast.yScale = 0.4
buttonEast.zRotation = CGFloat(Double.pi)
buttonWest.xScale = 0.4
buttonWest.yScale = 0.4
addChild(cameraNode)
camera = cameraNode
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
for touch in (touches ) {
let location = touch.location(in: self)
if (buttonNorth.frame.contains(location)) {
currentState = MoveStates.n
buttonNorth.texture = SKTexture(imageNamed: "Directional_Button_Lit")
isPressing = true
} else if (buttonSouth.frame.contains(location)) {
currentState = MoveStates.s
buttonSouth.texture = SKTexture(imageNamed: "Directional_Button_Lit")
isPressing = true
} else if (buttonEast.frame.contains(location)) {
currentState = MoveStates.e
buttonEast.texture = SKTexture(imageNamed: "Directional_Button2_Lit")
isPressing = true
} else if (buttonWest.frame.contains(location)) {
currentState = MoveStates.w
buttonWest.texture = SKTexture(imageNamed: "Directional_Button2_Lit")
isPressing = true
}
}
}

Answer 1

The problem was in my touchesBegan
I had this:
let location = touch.location(in: self)
but since I I had the nodes move with the camera I needed:
let location = touch.location(in: self.camera!)
