问题
I created a really basic app that just shows an MKMapView and the UserLocation. I'm having problems drawing this base map sometimes (it only shows pieces of the map), and whenever I pinch zoom the map, it fails to redraw, and just shows the blank gray tiles. The console shows this whenever it needs to get a new map tile:
/SourceCache/GoogleMobileMaps/GoogleMobileMaps-263.5/googlenav/mac/Loader.mm:231 server returned error: 502
This looks like a gateway error, but that doesn't make any sense, since I'm using open WiFi for testing. I haven't implemented any region zooming code, I just want to display and zoom the basic map first. I'm using iOS 4.2.1 (8C148), so I'm wondering if this is a problem with the newer iOS versions? Any ideas?
Edit: Works fine now, must just be a problem with Google's servers.
回答1:
Just started getting the same error. I've searched online and can't see anyone else having the issue (yet). Thought it was something I did, but suspect its at Google's end.

I think that the problem is solved now. It had to be a momentary Google Maps problem.
