Question - How to set a component's controller as a delegate for a gesture created using view attributes CKComponentPanGestureAttribute

Some might consider this to be too much "magic", but perhaps when the component controller implements UIGestureRecognizer, the functions provided by CKComponentGestureActions.h could automatically assign the controller as the delegate.

For now though, I'm not sure if there's a better alternative besides ditching CKComponentPanGestureAttribute, and instead handling the construction and delegate assignment of the gesture recognizer inside a component controller.

- (void)componentDidAcquireView
{
  [super componentDidAcquireView];
  _panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(didPan:gesture:)];
  _panRecognizer.delegate = self;
  [self.view addGestureRecognizer:_panRecognizer];
}

- (void)componentWillRelinquishView
{
  [super componentWillRelinquishView];
  [self.view removeGestureRecognizer:_panRecognizer];
}

You should need to do nothing to make this work.

While the controller isn't the delegate of the gesture, it is on the responder chain for the gesture. So, you should just implement -didPan:gesture: in your controller and boom.
