need help with some design issues on MKMapViewAnnotation

So I have a map view in which if I tap on the accessory view it would push a new view to the navigation controller. The issue is that I would also like to set a local variable of that view controller when this is tapped (in my view controller I have an instance called venue in which I'd like to set) The delegate that I am implementing is:

- (void) mapView: (MKMapView *) mapView annotationView:(MKAnnotationView *) view calloutAccessoryControlTapped:(UIControl *) control

What I was thinking was to subclass the MKAnnotationView and then have a venue stored there as well, but I think this defeats the purpose as MKAnnotationView is only supposed to be a view instead of a data storage. So what is the best way to do this?

In other words, the problem is that, each pin has a venue that I need to pass to the view controller instance through the delegate above.

If your annotation object (a class which conforms to MKAnnotation) already has a venue property, you can access it in calloutAccessoryControlTapped using view.annotation like this:

MyAnnotationClass *myAnnot = (MyAnnotationClass *)view.annotation;

DetailViewController *dvc = [[DetailViewController alloc] init...
dvc.venue = myAnnot.venue;
[self.navigationController pushViewController:dvc animated:YES];
[dvc release];
