Kas saaksite selgitada sõnumite järjestusliku töötlemise mehhanismi läbi vastajate ahela (Responder Chain)?

Response Chain is a mechanism through which an event or message is passed along a chain of objects until one of them handles it. In iOS, this is often used for handling touch events or user actions.

Each object in the chain has a reference to the next responder. If the current object cannot handle the event, it passes it to the next object in the chain.

Example:

• The user taps a button
• The event is first received by the UIButton
• If the button does not handle the event, it passes it to its superview
• Then, the event bubbles up through the view hierarchy until it is handled or reaches the top level

This allows flexible distribution of event handling and avoids tight coupling to a specific object.
