iOS: app crash when setting large region to MKMapView

I must do something wrong, I have code as following:

[_mapView setRegion:region animated:YES];

The app crashes in 5.0, 5.1 and 6.1 Simulator when I set a very large region to it.

the region is center at

Then I changed the code to 

[_mapView setRegion:[_mapView regionThatFits:region] animated:YES];

The code works for OS 5.0, 5.1 but still crashes on OS 6.1.

Any idea?

You should subtract some degrees of latitude/longitude from the span returned from your API

I suspect that the region "span" of 75382.1245843343 by 96613.0758612126 degrees is what's throwing up the problem. That region would cover a world with a circumference of over 8 million kilometres - rather larger than our own. Try using a smaller span that actually defines a region on the Earth?
