In this tutorial we will create an app that displays labels. Labels are created using the UILabel class. Particularly UILabel class implements a read-only text view. You can use this class to draw one or multiple lines of static text, such as those you might use to identify other parts of your user interface. The base UILabel class provides support for both simple and complex styling of the label text. You can also control over aspects of appearance, such as whether the label uses a shadow or draws with a highlight.
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.
