In Objective-C, an Object is, most basically, something you can message.
There are Class objects, every time you write something like [NSArray alloc] you are messaging the Class object.
Class methonds like -alloc or [NSNumber numberWithDouble: 2.0] return instances. And instances respond to instance messages like -objectAtIndex:
You can usually have as many instances as you want, but there is only one Class object for each class.

Gotcha, I understand how how it works but I am just failing to use the right terminology (syntax) to describe my problems. in my Class in the @interface I create what are called 'instance variables' and 'method headers'. Then in the @implementation section I define the methods for the @interface section.
Now in 'main', what is the correct way of saying this: "from the Class I create an Object", or "from the Class I create an Instance Object"?

I'd probably say "Object of class x" or "instance of class x" or even "instance of x". "Instance object" isn't wrong, per se, just a bit verbose.

"I create an instance of "class"" or "I create a "class" instance" or "I create a "class""
All of them make more sense with an actual class name.
"I create an instance of NSNumber"
"I create a NSString instance"
"I create an NSArray"
