iOS 7 is there a way to know when the MKTileOverlay is finished loading tiles?

Question

I would like to implement a zoom effect on the map (which I already have figured out), but after the the MKTileOverlay is finished loading the tiles. Is there anyway to know when those tiles have finished loading? I have tried all the other mapView methods and nothing seems to wait until the overlay loads before it runs. Thanks in advance.

Answer 2

Take a look at the MKMapViewDelegate method:
