Subclasses of MKAnnotationView

Question

I was wondering if anyone knows of any subclasses for the MKAnnotationView class. On apples documentation they say one example is the MKPinAnnotationView so I was wondering if there were other pre-created subclasses like the one used to track the devices current location. If anyone has tips for creating my own subclass of the MKAnnotationView class that be great as well.

Thanks, bubster

Answer 1

In case anyone is still interested in this:

You can get all the subclasses of a class using the Objective-C runtime functions, as described here: http://cocoawithlove.com/2010/01/getting-subclasses-of-objective-c-class.html

Other classes that inherit from MKAnnotationView are:

MKTransitCalloutView, MKAdAnnotationView, MKUserLocationView, MKUserLocationBreadCrumbView, and MKPinAnnotationView

where MKPinAnnotationView is the only one that is documented. All others are private classes that Apple uses internally.
