How does an NSView subclass communicate with the controller?

Question

I am brand spanking new to Cocoa programming, and am still kind of confused about how things wire together.

I need a pretty simple application that will fire off a singl

you can also use a selector calling method, define two properties in custom class:

@property id parent;
@property SEL selector;

set them in view controller:

graph.selector=@selector(onCalcRate:);
graph.parent=self;

and call as:

-(void)mouseDown:(NSEvent *)theEvent {
    [super mouseDown:theEvent];
    [_parent performSelector:_selector withObject:self];
}
