使用ios系统自带的MapKit framework进行定位

这样使用的是谷歌的地图和LBS信息， 估计后续苹果会自己做地图服务了

			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
{
}
