Answer from AI

In iOS, the Responders system forms an event handling chain (responder chain), through which events are passed from one object to another.

To disable or remove a participant from this chain, you can:

  • Change the structure of the view or view controller hierarchy, as the responder chain is built based on the hierarchy of objects.
  • Remove or disable the object from the hierarchy (for example, remove a view from its superview).
  • Override the next method in UIResponder to change the next element in the chain.

Example of overriding next:

class CustomView: UIView {
    override var next: UIResponder? {
        // Return nil to break the chain after this object
        return nil
    }
}

Thus, you can control who is next in the chain and exclude unnecessary participants.
