Objective-C - Overriding method in subclass

Question

I am having some trouble figuring out hour to accurately override a method in one of my subclasses.

I have subclass (ClassB) of another customclass (ClassA):

Answer 1

You just add your custom code in methodName in classB :

- (void)methodName
{
    // custom code

    // call through to parent class implementation, if you want
    [super methodName];
}
