UIView Basic Tutorial
UIView Basic Tutorial First of all, we need to introduce the fundamental concepts of application’s view architecture. We are going to present two basic classes the UIView class along with the related CGRect class (that is structure), that both are used in order to representation of an application. The UIView class defines a rectangular area on the screen along with the necessary interface for managing the content in that area. Particularly we create a specific object that handles at runtime the content of this area along with the interactions relative to it.
