Programming With Cocoa

The Cocoa programming environment is used to create native Mac OS X applications. Mac DevCenter features a variety of tutorials covering Cocoa. If you're just getting started and don't have an extensive background in "C," then start with Seth Roby's "C is for Cocoa" tutorial. As you become more comfortable in this environment, try some of Mike Beam's more advanced lessons. New tutorials are constantly being added, so be sure to check back regularly.

Understanding the NSTableView Class
This article will provide you with an in-depth introduction on how to use the NSTableView Cocoa class to display tabular data. You will first learn how to add an instance of that class to your application project using Interface Builder. Then, you will learn how to properly implement the data-source process used to retrieve the data to be displayed by the instantiated table. Jose Cruz shows you how. Aug. 8, 2006

Inside StYNCies, Part 2
In the first part of this two-part series, Matthew Russell showed you how to develop a user interface that lives up in your menubar like the system clock. In this final installment, he covers how to reverse-engineer the storage format of the StickiesDatabase file to develop your own API to Stickies.  Mar. 18, 2005

Inside StYNCies
Stickies is one of the handiest little apps out there. It's been bundled with Apple's operating systems for ages, but Apple hasn't yet taken advantage of the new possibilities for it. This first installment of a two-part series works through building a partial implementation of StYNCies, a neat little utility that synchronizes your Stickies to your iPod and/or iDisk. Mar. 11, 2005

Build an eDoc Reader for Your iPod, Part 3
In this conclusion to the series on building your eDoc reader, Matthew Russell shows you how to extract text from PDF documents. You'll accomplish this task by using an open source Java package called PDFBox and the not-so-well documented Cocoa-Java bridge. Jan. 7, 2005

Easy Code Documentation with Xcode
As a developer, you must not only use documentation but also provide it for your own code if you want to make it usable to others. Providing up-to-date and easy-to-navigate API documentation is a big step toward making your code accessible and useful. If you are a Mac developer, you can leverage the power of Xcode so that it requires minimal effort to create good documentation. Adam Behringer shows you how. Aug. 27, 2004

Higher-Order Messages in Cocoa
Higher-Order Messaging (HOM) refers to the treatment of a message as a data type, like an object, so that it can be used as the argument in another message. The grandest use of them by far is for fun uses of arrays; combining them, getting selections from them, and so forth. But they also have uses in exception handling. Rob Rix explains HOM in this tutorial. Jul. 16, 2004

Ten Things I Dig About Xcode
Following in the footsteps of "Ten Things I Dig About Panther," James Duncan Davidson further explores one of the facets near and dear to Mac developers--their application development environment. Apple is introducing Xcode, along with Panther, and Davidson takes it for a spin and reports on his initial findings. Oct. 24, 2003

The Double Life of Variables
The most basic duality that exists with variables is how the programmer sees them in a totally different way than the computer. When you're typing away in Project Builder, your variables are normal words smashed together, like software titles from the 80s. But when the machine compiles your code, however, it does a little bit of translation. At run time , the computer sees nothing but 1s and 0s. Seth Roby introduces you to this double life of variables. Oct. 7, 2003

Loop the Loop
No longer will our Cocoa programs be forced to merely plow through line after line of code, skipping comments and blocks in conditionals, never looking back. In lesson #4, we'll teach our programs how to jump around a bit, to take their time and enjoy the code we've written, to evaluate those lines a few times over. In this lesson, we'll examine the loop. Sep. 9, 2003

Go with the Flow
In the last tutorial in Seth Roby's ongoing Cocoa series, you learned the ins and outs of the role of functions in programming. In this third installement he tackles the notion of "the flow of control." Aug. 19, 2003

What's Your Function?
Basically, a function is a bit of code that you want to use over and over again. It does a little bit of work that you can change slightly by passing it different arguments. In this second tutorial in Seth Roby's ongoing Cocoa series, you'll learn the ins and outs of the role of functions in this type of programming. Aug. 1, 2003

C is for Cocoa
The debut of a new Cocoa series on Mac DevCenter. Unlike other articles you've worked with, this tutorial teaches you all the C you need to know to learn Cocoa, and ignores the rest.
