Question

I have a class with some methods neither declared in .h file nor in any category, I want to override these methods in the subclass to change the behavior slightly. I am thinking of simply redefining those methods in subclass. Is it a good idea? would it even work?

Answer 1

Ideally the subclass needs to know what the methods are if it wants to override the method and still call super.

One way of doing this is by having a separate header file which both the super class and subclass implementations both import.

// MyClass_protected.h

- (void)someMethodThatYouWantSubclassesToBeAbleToOverride;

Then

// MyClass.m

#import "MyClass_protected.h"

// MySubClass.m

#import "MyClass_protected.h"
