Is there any viewWillAppear equivalent function in NSObject class?

Question

I'm having an NSObject class having some methods, in my program execution i will call methods inside this NSObject class so whenever i call any of instance or class methods of this class i need some method like UIViewControllers viewWillAppear which calls whenever the view gets loads, How can i do this?

Any help is thanks in advance.

You mean whenever you're calling a method inside a (subclass of) NSObject, you want to be notified of this? Maybe you can something fancy with key-value observing or something...

But really, I'm wondering why you would want to do something like that.
