What should be the best approach in Objective-C allowing what inner class can do ?

What is the inner class in your Java code used for? I've usually seen inner classes used in Java for event/action listeners. If you're using Objective-C with Cocoa, handling events and actions is done in an entirely different way.

Thanks for you response,

The problem is the inner class is not used for event/action. The inner class in the Java source is used for accessing
instance variables of the "main" class as :


public class ClassB extends ClassA
{
/**
* This inner class
*/
protected class innerClass extends ClassC {
/**
* In this function innerClass use anInstance of ClassB
*/
public void foo() {

if (anInstance.doSomething()) {

//blabla;
}
}
}//End of the inner class

/**
* The constructor of ClassB.
*/
public ClassB() {
anInstance = null;
 }
}

I thought i could resolve this in Obj-C creating innerClass in a separated objective-C file and sharing (singleton) ClassB
but it doesn't work (may be i didn't well understand the goal of sharing instance ;-).
