Lately I’ve been linking to Apple’s developer documentation quite a bit when explaining the code here on Colour Me Cocoa. By now you should have realized that there is a world of information out there, all you have to do is search.

What you might not have realized though, is that the same world of information is also right in front of you. There’s no need for an internet connection when you have Xcode, all of the documentation can be found right at your fingertips!

Jeff Atwood of The Coding Horror wrote recently about how the majority of people applying for programming jobs cannot solve even the simplest of problems within a few minutes. Naturally, upon reading this, I opened up Xcode and got cracking.

I already knew the solution upon reading the definition of the problem, but could you do it? If you’re only experience writing code is from reading this blog, then the answer is no. So lets delve further into the world of Objective-C and learn a few more tricks.

Apple have just updated the WWDC website with information on the six session tracks available.

The six tracks available include

• Leopard Innovations
• Mac OS X Essentials
• Developer Tools
• Information Technologies
• Graphics and Imaging
• Content and Media

Needless to say, as someone starting out in the world of Cocoa development I’m most interested in the first 3 tracks listed above. Each of which look like they will be extremely useful for both seasoned and amateur developers.

Up until now we have been writing code exclusively in the C language. C has served us well, but it is now time to move on. Objective-C is the language of choice for Cocoa application developers.

What Is Objective-C?

Objective-C is an extension of the C language. Everything that we have learned so far, works equally well in Objective-C. What Objective-C offers us is a new way of thinking about code. It allows us to program at a higher level using Object Oriented Programming Techniques. The Apple Developer Connection has a great introduction to the Objective-C Language which I recommend reading.

Quick piece of house keeping. I’ve just installed a new wordpress plugin by Lester Chan that allows you to rank posts on this site. Starting from now you can rank a post from 1 (bad) to 5 (most excellent).

So even if you don’t feel like commenting you can still let me (and other readers) know what you think about a particular post. That way I’ll know if I’m doing well or if I need to be clearer when writing about certain topics.
