macOS Syntax question

[larswik]

After I defining a Class. You create an instance of that Class which is then called an Object, Instance Object or both?

Trying to get my syntax down so I can communicate better with problems.

Which language? I'd say either for most languages.

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.

"Object" and "Instance" are fully equivalent synonyms. Ulsing them together is merely redundant - sort of like saying "follow the highway road."

Thanks. that is what I needed to know the mean the same thing.

thanks!

-Lars

"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"
