Scenekit detecting User tapped object

Question

I recently started using scenekit for scenekit in iOS 8. I am facing difficulty in detecting whether the user has tapped or pressed on the object. Is there any way to do tha

Answer 1

Add a tap gesture to the object and check whether it is a SCNNode()

     @objc func tapGestureRec(sender: UIPanGestureRecognizer? = nil){
            let location: CGPoint = (sender?.location(in: self.view))!
            let hits = self.sceneKitView.hitTest(location, options: nil)
            if let tappedNode : SCNNode = hits.first?.node {
                ...
            }
     }
