How to assign UIGestureRecognizerDelegate to CKComponentController

Question

I use the next code to setup UIPanGestureRecognizer in my component:

MyComponent *c =[super newWithView:{
  [UIView class],
  {
    {
      CKComponentGestureAttribute(
      [UIPanGestureRecognizer class],
      &setupPanRecognizer,
      @selector(panGesture:context:),
      {}
      )
    },
    {
      @selector(setUserInteractionEnabled:), @YES
    }
  }
  }
  component: [MyOtherComponent newOtherComponentWithMode:model context:context]];

I process panGesture:context in MyComponentController object.

My problem is that UIPanGestureRecognizer blocks feed view from scrolling. In order to fix this I want to use UIGestureRecognizerDelegate protocol and allow both (scroll view and my pan) recognizers to work simultaneously.

My question is how can I assign my component controller as a delegate for UIPanGestureRecognizer? setupPanRecognizer is just a C function and it does not have reference to MyComponentController object or even the component itself.

The only way I see now is to get list of gesture recognisers somewhere in didUpdateComponent method in my controller, find the right one and assign delegate there. Does ComponentKit provide any solution to this?

CKComponentViewAttributeValue CKComponentGestureAttribute(Class gestureRecognizerClass,
                                                      CKComponentGestureRecognizerSetupFunction setupFunction,
                                                      CKComponentAction action,
                                                      CKComponentForwardedSelectors delegateSelectors)

You can find the "delegateSelectors" argument at last, so you could try to pass in a vector of selectors which you would like to response in the controller.
