使用ios系统自带的MapKit framework进行定位

CLLocationCoordinate2D coordinate;
coordinate.latitude = gpsInfo.lat;
coordinate.longitude = gpsInfo.log;

MKReverseGeocoder * reverseGeocoder = [[MKReverseGeocoder alloc] initWithCoordinate:coordinate];
reverseGeocoder.delegate = (id<MKReverseGeocoderDelegate>)self;
[reverseGeocoder start];
[reverseGeocoder release];

#pragma mark 使用mapkit定位的回调
- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark
{
//把获取到的地址拼接起来
NSString * myAddress = [NSString stringWithFormat:@"%@%@%@",placemark.country,placemark.locality,placemark.thoroughfare];
}

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error
{
}
