Best way to define private methods for a class in Objective-C

Question

I just started programming Objective-C and, having a background in Java, wonder how people writing Objective-C programs deal with private methods.

I understand there

Answer 1

You could try defining a static function below or above your implementation that takes a pointer to your instance. It will be able to access any of your instances variables.

//.h file
@interface MyClass : Object
{
    int test;
}
- (void) someMethod: anArg;

@end


//.m file    
@implementation MyClass

static void somePrivateMethod (MyClass *myClass, id anArg)
{
    fprintf (stderr, "MyClass (%d) was passed %p", myClass->test, anArg);
}


- (void) someMethod: (id) anArg
{
    somePrivateMethod (self, anArg);
}

@end
