Worthy goals indeed. Apple became so enamored of the Jaguar name that they ended up putting it onto the box in which Mac OS X By the end of the book, you will have learned enough about Cocoa and Objective-C to set you on your way to higher learning, and for that, there are plenty of other books available: Building Cocoa Applications: A Step-by-Step Guide, by Simson Garfinkel and Michael K.

Programming is a funny art, and sometimes it is invaluable to see several approaches to the same subject matter. To be a true master of the craft, you'll probably want to read each of these books and glean from each what you can.

When Apple updates their documentation, they often first post the revisions online, so you might want to keep that URL handy.

Additionally, there are some online resources-mailing lists and web sites-that you should subscribe to and read frequently. A listing of these resources can be found in Appendix B, located at the back of this book. This book assumes you have a basic knowledge of ANSI C and that you're open to learning the concepts of object-oriented programming. If you're not familiar with C and you haven't programmed with Java or some other compiled language, you might want to hold off on reading this book just yet.

Not that you can't pick something up from reading it, but this book is better suited for newcomers. Who Should Read This Book As mentioned earlier, this book was written for programmers who are interested in learning how to develop Cocoa applications using the Objective-C language.

It assumes that you have some experience with C programming, as well as a basic understanding of computerscience concepts.

If you're familiar with C or Java, you should have no problem picking up Objective-C. Some people will find this book too basic or too advanced for their liking.

For example: Novice programmers If you have never programmed before and want to learn the basics of programming, you should start off reading an introductory programming text. Kernighan and Dennis M. Ritchie Prentice Hall Practical C Programming, by Steve Oualline O'Reilly These books will introduce you to the concepts of programming with C, giving you the foundation you need before reading this book.

You might use this book as a refresher to come up to speed, but it probably won't be the Nirvana you're searching for. Java developers This book covers Cocoa using the Objective-C language. If you are a Java developer and don't mind learning a new language learning new languages is always good for you! However, if you want a strict treatment of Cocoa with Java, this book is not for you.

What You Need to Know Extensive programming experience is not required to complete the examples in this book. If you have experience with an object-oriented programming language such as Java or Smalltalk, you should find the concepts of Objective-C easy to comprehend. If you don't have experience with object-oriented concepts, don't worry; we will try our best to guide you through the terminology and to give you pointers to other texts and reference material.

No prior experience programming on Mac OS X is necessary to complete the tutorials in this book. We'll show you how to use the Developer Tools that come with Mac OS X and show you how to build your first Cocoa application in no time.

At some point you should explore the wealth of developer documentation that Apple installs with the Developer Tools. Mac Help from the Finder. As mentioned earlier, Apple often posts updates to its documentation online first, so you should check here if a document on your system doesn't have the answer for which you're looking.

The code for these examples is contained within the text, but you may prefer to download a disk image. If you use this book with a later release of any of these products, the user interface and features may be different from those shown in the book, but everything should work.

The index of the row is obtained by passing the selectedRow message to the itemList object. The newName string is obtained from the cell by using the stringValue message.

Bundling a CD would increase the cost of production and the cost to you. It is our belief that anyone reading this book has access to an Internet connection and would rather save money by simply downloading the example code off the Web. The first three parts are organized so that each chapter builds upon the previous one.

You should start at the beginning and proceed sequentially until you've read through the last chapter.

Most chapters contain example applications for you to work through, as well as exercises that build upon the material covered. Each chapter's applications and exercises are selfcontained and do not spread across chapters. Part I Cocoa Overview and Foundation introduces the Cocoa frameworks and describes the highlevel features they provide application programmers, as well as how they fit with other Mac OS X frameworks.

It also includes a brief introduction to object-oriented programming, the Objective-C language, and Apple's development tools.

The chapter then goes on to describe the wide array of tools and utilities available to assist in building, debugging, and performance-tuning applications on Mac OS X. Chapter 3 Explains the benefits of object-oriented programming practices as compared to procedural programming and provides an introduction to the terminology and core concepts needed to use the Cocoa frameworks effectively.

It also includes a primer on the Objective-C programming language. Chapter 4 Provides a series of mini-tutorials to introduce the Cocoa Foundation, including strings, arrays, collections, utility functions, and memory management.

This section uses a series of examples to illustrate the concepts presented. The techniques and concepts you learn in each chapter will lay the foundation for the next chapter. You will also learn about nib files and how to use them in your applications. Goes into detail about how the windowing system works, as well as how to create View and Controller objects to present a user interface.

Chapter 7 Cocoa's default set of controls covers most of the common UI needs that applications have, but they can't cover everything.

Programming Mac OS X with Cocoa for Beginners/Objective C, the language and its advantages

Your application may need to present a specialized view onto a data source or simply draw arbitrary content to the screen. This chapter shows how to create these custom views. Chapter 8 Introduces the event loop and explains how events propagate along the responder chain. It also covers how events are queued and dispatched, as well as how event delegation works. Shows how to work with the data-bearing objects of an application.

The chapter also shows how this information can be utilized with the Controllers and Views of an application and how it can be read from and written to storage.

Part III Many applications today, such as word processors and web browsers, are built around the concept of a document. While this guide only covers how to use Xcode, you can get an overall view of how to make iOS apps by reading my How to Make an App with No Programming Experience guide.

Click the button below to get my Xcode cheatsheet with references and my favorite keyboard shortcuts! Get the Xcode Cheatsheet 1. Where Can I Download Xcode? The easiest way to get Xcode is through the Mac App Store. Click the link to go to the listing. Just visit the Apple Developer page for Xcode.

If your interface looks different, make sure you have Xcode 10 and not an earlier version. Keep in mind that you can adjust the size of each of those panes by hovering your cursor over the boundaries of each area and dragging. Then you can use the View buttons to hide those 2 panes to give your editor more visible space. The Navigator Area In this pane, there are a bunch of different navigators that you can switch between using the Navigator selector bar refer to diagram.

The three navigators that you will use a lot are the Project, Search and Issue navigators. You can also right click on the project navigator and create new files or add existing files to your project. Or you can drag folders or files from your computer directly onto the project navigator and will popup a dialog asking how you want to add the files.

If you double click a file instead, it will open a new window which can be useful when you have dual monitors. The root node of the project navigator is your Xcode project file indicated by the blue icon. If you click that, the project properties will open in the editor area.

Search Navigator With the search navigator tab, you can easily look for pieces of text in your project. Issue Navigator The issue navigator shows you all the problems with your app. It will also show yellow Warnings in the issue navigator. This is where all the coding happens. As mentioned in the project navigator section, when you click a file there, it will open the contents in this editor area for you to edit the contents. Navigation within the editor area There are these little back and forward arrows in the upper left corner of the editor area.

They act like the back and forward buttons on your browser and they let you navigate to previously viewed files.

Another way to quickly get to the file you need is to use the Jump Bar see diagram. The jump bar allows you to quickly drill down through your groups and find the file you need.

That does it for navigation within the editor area however, it still has some tricks up its sleeve.

It looks like a two pane view.The difference between these two concepts is in how the code referenced by the method or message name is executed. Since you have experience with object-oriented concepts and programming, there are some sections that you will be able to skim.

Issue Navigator The issue navigator shows you all the problems with your app. They include books for those just starting out, those who wish to increase their knowledge, and those who need reference material.

We'll be covering this in detail in the next chapter, so don't worry about it for now. Message passing also does not require that an object be defined at compile time. In Objective-C one does not call a method; one sends a message.
