I'm not entirely sure I understand what you're saying, but I suspect you're 
applying a C++ or Java understanding of objects to Objective-C, and that 
doesn't work.

What we *call* an array of Obj-C objects is *really* an array of pointers to 
objects (and a NSArray isn't even an array of pointers in the C sense -- it's a 
kind of array behavior, not an array data structure). In Objective-C, every 
object is a separate memory allocation, and so is always referred to via a 
pointer. The concept of "getting" an object from its pointer doesn't make any 
sense in Obj-C terms.

I'm not sure where to go next with this ...
