How is the interaction between components of the UIKit framework carried out?

In UIKit, interaction between components occurs through delegates, notifications (NotificationCenter), target-action, and direct references.

• Delegates allow one object to inform another about events or changes in state. For example, UITableView uses a delegate to handle cell selection.

• NotificationCenter is a message broadcasting mechanism that allows multiple objects to subscribe to events without direct coupling.

• Target-action is a pattern where controls (e.g., buttons) invoke methods on a target object when the user interacts.

• Direct references mean objects can hold references to other objects to call methods or access data.

Thus, UIKit provides a flexible and modular architecture for component interaction, enabling the construction of complex interfaces with separation of concerns.
