"Official" syntax for referring to method of a class in Objective-C?

Question

In Ruby, when referring to the "downcase" method of the class "String", I write String#downcase. When talking about the "new" class method, I write String.new.

Is there something similar for Objective-C?

Answer 1

If you are referring to a method like:

+ (void)someClassMethod;

on class MyObject then you would call it like this:

[MyObject someClassMethod];

Answer 2

gdb uses +[MyClass foo] and -[MyClass bar];

Answer 3

Given a class declaration like this

@interface MyClass (NSObject)
{}

+ (id)classMethod;
- (id)instanceMethod;
@end

it is common practice to refer to classMethod as +[MyClass classMethod] or more compactly +classMethod if the class is clear. Similarly, I would refer to instanceMethod as -[MyClass instanceMethod] or -instanceMethod.
