How do I drag and drop a sprite in Swift 3.0?

Question

All i\'m trying to do is be able to drag and drop a sprite across the screen. I\'ve tried the following code:

override func touchesBegan(touches: Set

        

Answer 1

I have an implementation where I've subclassed a UIImageView and called it a "DraggableImage"

override func touchesBegan(_ touches: Set, with event: UIEvent?) {
        originalPosition = self.center
    }

override func touchesMoved(_ touches: Set, with event: UIEvent?) {
        if let touch = touches.first {
            let position = touch.location(in: self.superview)
            self.center = CGPoint(x: position.x, y: position.y)
        }
    }

override func touchesEnded(_ touches: Set, with event: UIEvent?) {

        self.center = originalPosition
    }
