Objective-c: How can I get Class instance in class method

Question

I have 2 classes, Parent and Child, and Parent has a class method named func. Now I want to get Class instance in func method to distinguish which class is caller.

Answer 1

If you just want to log it/get it as a Class, you just need self. Thats it. So like

+ (void)func {
    Class class = self;
    NSLog(@"%@ call func", class);
}

or

+ (void)func {
    NSLog(@"%@ call func", self);
}

also, if you want to get the name as an NSString, NSStringFromClass(self) has you covered. (As a char *, class_getName(self) is what you're looking for)

Answer 2

To get the current class object, you should be able to do:

[self class];

As self will refer to the class instance, because it's a class method. Class is a method defined in NSObject, which returns the class for the object.

Edited to avoid confusion...
