Hi All.
I'm a real beginner in Objective-C/Cocoa developing and I have two questions.
First of all I want to ask to you if exists a list dedicated to beginners as I
am. This in order to not bother the real programmers in this developer list
with real beginner question.

Does the stack-based idiom allow returning an autoreleased object? I'd
think you'd end up with code like this:
- (id)arrayWithStuff {
StackAutoreleasePool();
NSArray *array = [NSArray arrayWithObjects:obj1, obj2, etc, nil];
return array;
}
which would essentially translate into:

Boy do I feel silly. I guess I'm not used to the layout of the new
