You'll want to make all basic classes a subclass of NSObject so alloc/
dealloc, retain/release function properly. Unless you really want to
implement you're own alloc/dealloc method, but I think that's
unnecessary work.

that all Objective-C classes implicitly derive from Object (such as
in C# or
Java).
However, such a class has a problem. It cannot be allocated or
initialized.
Because it can never get the alloc message as the alloc message is
declared
in the Object class. My question ,therefore, is how can such classes
be
instantiated. Is there a library function for that? Surely, the
standard
alloc function must be using such a function. Or should I just
derive all
classes from Object.
