How to Move my Node to touch location CGPoint mirrors y-axe

Hello there, I have a Problem with CGPoint in swift. I want a node to move towards a touch location. So far so good but when I touch the screen he moves correctly on the x-axe but in the opposite direction on the y-axe. (So when i press top right corner he walks to the bottom right corner)

I would appreciate any hint !

The node is on the scene and when the touch occurs I want to call my function.

This is how I get the location of the touch and call my function to move the player:

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {

        var touch = touches.first as! UITouch
        var point = touch.locationInView(self.view)

        movePlayer(point)

    }

func movePlayer(point: CGPoint){

        let actualDuration = 1
        let actionMove = SKAction.moveTo(point, duration: NSTimeInterval(actualDuration))
        //let actionMoveDone = SKAction.removeFromParent()

        player.runAction(actionMove)
    }

Also i would like to know how I to call my function correctly from another class. If i call the GameScene().moveplayer(point) the move player is executed and gehts the CGPoint (I can print it) but it will just ignore the runAction?! (so nothing happens)

This works for me...dont ask me why :( still would love for someone to explain!

override func touchesEnded(touches: Set<NSObject>, withEvent event: UIEvent) {

        var touch = touches.first as! UITouch
        var point = touch.locationInNode(self)

        println(point)
        movePlayer(point)

    }
