  • About Objective-C Essentials - Techotopia
    you wanted to learn Objective C in order to develop some software to run on Apple s Mac OS X operating system Now however there is a greater likelihood that you plan to develop an application to run on the iPhone The iPhone after all runs a special version of Mac OS X Given that Objective C is the programming language of choice for this operating system it should come as no surprise that before you can develop iPhone applications you first need to learn how to program in Objective C The objective of this book is to teach the skills necessary to program in Objective C using a style that is easy to follow rich in examples and accessible to those who have never used Objective C before Topics covered include the fundamentals of Objective C such as variables looping and flow control Also included are details of object oriented programming working with files and memory and the Objective C Foundation framework Those who have developed using other programming languages such as C C C or Java will find much about Objective C that is familiar That said there are aspects of the language syntax that are unique to Objective C Even experienced programmers should therefore expect to spend some time transitioning to this increasingly popular programming language before embarking on a major development project Whatever your background and experience we have worked hard to make this book as useful and helpful as possible as you traverse the Objective C learning curve Supported Platforms After all this talk about Mac OS X and the iPhone it is important to note that Objective C is not confined to Apple s operating systems In fact Objective C is available on a wide range of platforms including Linux NetBSD OpenBSD FreeBSD Solaris
