Definition and use of framework fundation and Uikit frameworks

Foundation Framework provides basic system services for all applications

Your applications, as well as UIKit and other frameworks, are built on the foundation of the Foundation framework. The Foundation framework provides a number of basic object classes and data types, making them the foundation for application development. It also has a number of conventions (for tasks such as canceling assignments) that make your code more consistent and reusable better.

Use Foundation:

• Create and manage sets, such as arrays and dictionaries

• Access images and other resources stored in the application

• Creating and managing strings

• Publish and observe notifications

• Create date and Time objects

• Automatically discover devices on an IP network

• Manipulating URL flows

• Execute code asynchronously

The UIKit framework provides classes that can be used to create a touch-based user interface

All IOS apps are based on UIKit. Without this framework, applications cannot be delivered. UIKit provides the infrastructure for drawing on the screen, handling events, and creating common user interface elements. UIKit also organizes complex applications by managing what is displayed on the screen.

Using UIKit:

• Building and managing the user interface

• Handle touch-and motion-based events

• displaying text and Web content

• Optimize your application for multi-tasking

• To create a custom user interface element
