From me, just something simple for now.

well, you can go and download the sample code off here: http://developer.apple.com/iphone/

Look for sample code. Requires free registration though.

Obj C programming is still Obj C programming, whether for iPhone or for the Mac, or anywhere else that uses Obj C. What you need to get used to is the Cocoa Touch framework (which is still very similar to Cocoa for the Mac). Take note though when you look through the iPhone code samples, you'll find that they tend to build up the interfaces manually via code rather than using Interface Builder unlike the code examples for Mac development. This is actually for performance reasons.

For those confused about the []

take this line for example:

UITextView *textView = [[UITextView alloc] initWithFrame: CGRectMake(10.0f, 10.0f, 320.0f, 480.0f)];

in Java (for example) syntax, it'll be something like:

UITextView textView = new UITextView(new CGRectMake(10.0f, 10.0f, 320.0f, 480.0f));

and
[textView setEditable:YES];

is like: textView.setEditable(YES);

syntax wise, this is one of the areas where OBJ C differs. But you can still mix in C/C++ into your OBJ C code though.

alloc is how u allocate memory for the particular object that you're initializing (instead of using malloc), and the init* basically calls the constructor

and then the purist would add this to the bottom of that code snippet:

[textView release];

to remove the memory reference to textView as defined earlier, as there's already a reference to it in the window when it was added there as a sub view

For those wanting to get started on Cocoa Touch development:

This URL will open up in iTunes, where you can download for free the Lecture video as well as Lecture notes of the iPhone Application Programming subject that is taught at Stanford Uni.

There's only 4 lectures on there so far, but more will be added as the semester goes on. Can expect new materials every monday and wednesday (or at least 1-2 days after those classes)

Objective C is pretty easy actually. Just a matter of getting used to their slightly different syntax. The bulk of the time is actually spent familiarizing yourself with the Cocoa Touch framework.

Its the same for any language out there too. for example: Java as a language is easy. But is the frameworks such as J2EE and so forth that consumes the most time in the learning process.

just downloaded it to my office, and collecting the whole bunch of files tomorrow (SDK, OS images + itunes 8.2 beta). And yes, you cannot revert back to the 2.x OS after updating. Of which is why I'm not updating it on my iPhone, but testing it out for the time being on a pair of iPod Touches (1G and 2G)

Just to set the record right, those classes that had been held at Apple Malaysia's office are not conducted by Apple. Its actually conducted by a 3rd party of which had gotten Apple Malaysia to agree to let them use their training area for a few sessions.

I actually got some bits and pieces of code that displays the forum in a native app, but haven't had the chance to do much more 'cause of time constraints
