Development Environment
• Most Object-Oriented Development Environments consist of:
 An Object-oriented Programming Language
• Objective-C
 A library of Objects
• Cocoa Frameworks
 A Suite of Development Tools
• Xcode and Interface Builder
 A Runtime Environment
• Acts as a Kind of Operating system for Objective-C.
• Typically, you don’t need to interact with runtime
• directly

Frameworks
 Frameworks – classes compiled together into a reusable
library of code.
 Built in frameworks - /System/Library/Frameworks
 Cocoa is made up of:
Foundation: Standard values, collection, utility classes.
Strings, dates, lists, threads, timers.
AppKit: User Interface Frameworks. Windows, buttons,
text fields, events, drawing classes
Core Data: Core data is a persistence frameworks. Makes it
easy to save and reload files.

Objective - C
 Objective-C is a superset of C, which enables sophisticated Object oriented
programming mostly based on SmallTalk.
 Designed to give C full OOPS support.
 Objective-C code is compiled by gcc, the GNU C compiler. It enables to
freely mix C, C++ and Objective-C code in a single file.
 Objective-C is the foundation of Cocoa – a whole lot of utility functions.
 Thousands of classes/libraries are wrapped into the Foundation
Frameworks.
 Cocoa also contains interface classes – UIKit and other classes like the
MapKit, Address Book UI all wrapped into Cocoa Touch.
