Scenekit detecting User tapped object

问题:

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 that?

See the documentation for the hitTest method. Call that from wherever you're handling touch events to get a list of 3D scene objects/locations "under" a 2D screen point.

An easy way to get sample code that shows the hitTest in action is to create a sample app using the Game template in XCode6. Create a new project, select the "Game" template.

The hitTest code should be there in the implementation of:

- (void) handleTap:(UIGestureRecognizer*)gestureRecognize
