    NOTE:  it is highly recommended that the propertyListener instance is part of s custom view class, and in that class's will_close method, call stop() on the instance.  otherwise, it will continue to poll even after the view is closed, and could cause problems later.

    view  -  the view to watch
    propertylist   -  list of properties to watch. must be a list even if only one prop, e.g ['frame']

Demo of a custom ui.View subclass that embeds a native map view using MapKit (via objc_util). Tap and hold the map to drop a pin.

The MapView class is designed to be reusable, but it doesn't implement *everything* you might need. I hope that the existing methods give you a basic idea of how to add new capabilities though. For reference, here's Apple's documentation about the underlying MKMapView class: http://developer.apple.com/library/ios/documentation/MapKit/reference/MKMapView_Class/index.html
