SKLabelNode upside down possible?

Question

I'm developing a game in xcode 6 with swift. I have a scorelabel var scoreLabel: SKLabelNode!. Now in one of my methods I show my label:

scoreLabel = SKlabelNode(fontNamed: "TrebuchetMS-Bold")
scoreLabel.text = "\(score)"
scoreLabel.fontSize = 30
scoreLabel.fontColor = SKColor .redColor()
scoreLabel.position = CGPoint(x:780, y:180)
addChild(scoreLabel)

That shows my score as for example: 2500. Is it possible to show this upside down?

• 2
• 5
• 0
• 0

Sorry, I wrote this as list, because I wasn't able to write upside down here.

Thanks for answers.

You can create a custom class to loop through each character in the string and create a separate SKLabelNode for each character.

class SKVerticalLabelNode : SKNode
{
    var fontName : String = "" {
        didSet {
            self.updateLabelProperties()
        }
    }

    var fontSize : CGFloat = 10.0 {
        didSet {
            self.updateLabelProperties()
        }
    }

    var fontColor : UIColor = UIColor.whiteColor() {
        didSet {
            self.updateLabelProperties()
        }
    }

    var text : String = "" {
        didSet {
           self.updateLabelProperties()
        }
    }

    func updateLabelProperties () {
        self.removeAllChildren()
        let length = countElements(text)
        var yPosition : CGFloat = 0
        for character in reverse(text) {
            let label = SKLabelNode(fontNamed: self.fontName)
            label.fontColor = self.fontColor
            label.fontSize = self.fontSize
            label.text = String(character)
            label.position = CGPointMake(0, yPosition)
            yPosition += label.frame.size.height
            addChild(label)
        }
    }
}

It can be used like this

let scoreLabel = SKVerticalLabelNode()
scoreLabel.fontName = "TrebuchetMS-Bold"
scoreLabel.text = "2500"
scoreLabel.fontSize = 30
scoreLabel.fontColor = UIColor.redColor()
scoreLabel.position = CGPoint(x:180, y:180)
addChild(scoreLabel)
