Call subclass's method from its superclass

Question

I have two classes, named Parent and Child, as below. Parent is the superclass of Child I can call a method of the super

Answer 1

You could use this:

Parent.m

#import "Parent.h"

@implementation Parent

- (void) methodOfChild {

    // this should be override by child classes
    NSAssert(NO, @"This is an abstract method and should be overridden");    
}

@end

The parent knows about the child and child has a choice on how to implement the function.
