The document provides an overview of basic iOS development concepts including MVC architecture, delegation, target-action, UIApplication architecture, UIViewController catalog, and UIView architecture. It explains that the MVC pattern separates an app's data model, user interface views, and behavior/control logic. It also outlines how iOS uses delegation and target-action to define behaviors separately from components.

Component Behavior
 Component’s behavior is defined in another
pre-defined class.
 Must keep relationship between component
and behavior with field relation.
