Touch not responding outside UIView

Hello!

I am new to this and there will probably exist a short and quick answer to this problem, to give a short overview:

What I want: to increase the size of buttons on touch of the +-sign, then to highlight the correct button if the corresponding button is touched inside.

So far: I have designed a custom class "AddButton.swift" inherited from UIControl, and inside that control I have added a few buttons "AddButtonOption.swift" (also custom class inherited from CALayer), everything works great so far and looks good on the screen.

Problem :The problem strikes when I have resized the buttons, the touch only seem to respond inside the old UIView from before it has been resized (to a bigger size). I guess the problem lays in "touch.locationInView(self))", but after many attempts I have to ask for advice.

Code of interest:

AddButton.swift

override func beginTrackingWithTouch(touch: UITouch, withEvent event: UIEvent?) -> Bool {
    ...
    let getBig = CATransform3DScale(button1Scale,resizeFactor, resizeFactor, 1.0)
    ...
    for tbutton in button{
        UIView.animateWithDuration(1.0, delay: 0, usingSpringWithDamping: 0.04, initialSpringVelocity: 0.2, options: .CurveEaseOut, animations: {tbutton.transform=getBig}, completion: nil)
    }
    ...
}

AddButton.swift

    override func continueTrackingWithTouch(touch: UITouch, withEvent event: UIEvent?) -> Bool {
        for buttont in button{
            if(buttont.containsPoint(touch.locationInView(self))){
                buttont.touchOver()
                buttont.setNeedsDisplay()
            }else{
                buttont.touchDisappear()
                buttont.setNeedsDisplay()
            }
        }
        return true;
    }

AddButtonOption.swift

override func containsPoint(p: CGPoint) -> Bool {
        return CGPathContainsPoint(sl.path, nil, p, false)
}
