iphone - MKMapView from google maps URL

i'm using the MKMapView first time.

I need to show some address in one MKMapView: the address (take parsing an xml file) are google maps links.

Is possible to set the coordinates of the MKMapView using the URL? Or i need to take the longitude and latidude?

thanks

To plot a point on a MKMapView, I'm pretty sure you need the longitude & latitude of the point.

As far as I'm aware using the iPhone MKMapView & associated classes, you can do reverse geocoding (ie - convert a longitide & latitude into an address), but I think going the other way - forward geocoding (address into a longitude / latitude) is not supported.

There are plenty of services you can use though that aren't google that do forward geocoding - one of which is Geonames. The free service has no support contract, so it's liable to stop working without notice - but it seems to do the trick OK for small or offline operations.

You have to take the longitude and latitude position of the point otherwise you can provide address to google map service, it will provide a lat and long position in JSON or XML format(for reference see google Reverse geo coding).

http://googlemapsapi.blogspot.com/2006/06/geocoding-at-last.html

use NSMutableRequest class to find-out the lat and long, for reference urlString- 

NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv", theAddress];
NSString *locationString = [[[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:urlString]] autorelease];

for MKMapView you can refer this blog- link
