What is the role of the RunLoop mechanism in event handling and queue management in an application?

RunLoop is a mechanism in iOS that manages the event processing loop and task queues. It runs continuously, waiting for events (such as touches, timers, network responses) and dispatching them for processing.

Role of RunLoop:

• Keeps the application active by processing incoming events.
• Manages task queues, allowing code to execute asynchronously without blocking the main thread.
• Enables scheduling of tasks to be executed at specific times.

For example, when a user taps a button, the event is placed in the RunLoop queue, which then calls the appropriate handler. This ensures interface responsiveness and efficient resource management.
