Re: pointers in objective-c?

Correct, all objective-C objects are allocated on the heap (like using 
new in C++). The compiler will not allow you to allocate objects on 
the stack.

There are ways to trick the runtime into treating an area of the stack 
as of it were an object, but the caviats are a list as long as my arm--
it's just not worth it.
