如何找到城市并在MKMapView上显示？

Question

I'm developing an iPhone application to search cities on a MKMapView. The user specify a city and then it show its location on a MKMapView. Is that possible?

Thanks.

EDIT : iOS 5 now includes CLGeocoder , which will do just that for you.

You could use Google's Geocoder REST API . A request looks like this:

http://maps.google.com/maps/api/geocode/json?address=city&sensor=true_or_false

Since the response is in JSON format, you'll need a JSON parser .
