I am new to object-oriented programming and am attempting to learn using OSX PB on my home machine. I also have several NeXT's and went through the excellent exercises in "NeXTstep Programming. Step One..." and am finding it fairly easy to adopt to the slightly different UI of Interface Builder and Project Builder in OSX after using these programs in NeXTStep 3.3. The core concepts of Class, method, instance, inheritance, action, outlet, etc. are beginning to make sense to me. I am attempting the Stepwise "Vermont Recipes" series and got about halfway through the first recipe before I became a little confused - I am afraid that these exercises are a little advanced for me.

It appears that the key to programming in Cocoa, after the key concepts have sunk in, is to have an easy reference to the hierarchy of classes used in Cocoa development. One needs, it seems, a graphical representation of the class hierarchy similar to the one for NeXTstep in the "NeXTstep Programming..." book. Furthermore, it would be nice to have an easily referenced description of each class. I realize that the latter can be found in the online (html) documentation, but I was looking for something a little more accessible.

I was wondering in any experienced Cocoa developers could give me some feedback about where to find these items or, indeed, whether there is some other way to obtain the needed information (such as an online "class browser" or something similar)?

Thanks very much.

Here's an excellent ObjC/Cocoa tutorial:
http://developer.apple.com/techpubs/...tiveC/ObjC.pdf

Thanks, I am actually about 10% through that document (last year's version - I downloaded it 6 months ago and printed it). It is a fairly clear treatment, though lacking in examples.

I'm still looking for a convenient reference on the actual Cocoa classes.

there is class documentation but it's incomplete, if you have the PB dev tools they're hiding somewhere in the documentation folder i think. wish it was finished. :-P

There was a book called something like Discovering Openstep: Rhapsody which I downloaded from the Mac OS Server Training area a while back. The PDF was called "Rhapsody_DiscOS.pdf". There is also something about the Yellow Box (its 16 chapters are individual pdf files.) with associated Exercise Materials.

They both are a little out of date as far as the versions of PB and IB they use. You have to use a little creativity to make the things work.

I feel like I got a lot out of both those documents.

Good luck,
Dave
