implement delegate method for CPResponder in viewController but not success

I am trying to capture touch event in CPLayerHostingView, 
it shows there has a CPLayer inside CPLayerHostingView.
And there are 4 touch event send to that CPLayer.

As I look deep into CPLayer, it has delegate method of CPResponder which 
already implemented in CPLayer.M 

So, How can I let my CPResponder delegate method implement in my view 
controller instead of CPLayer.M .

I tried set delegate to self but not working.
