Open Google Maps from iPhone and show route
<p>I was wondering how I can open Google Maps from my iphone app so that Google Maps shows the route when you arrive at the web page?</p>

<p>Today I use code that <strong>only</strong> shows the coordinate.</p>

<pre><code>        NSString *latlong = [NSString stringWithString: @"59.33267,18.07361"];
        NSURL *url = [[[NSURL alloc] initWithString:[NSString stringWithFormat: @"http://maps.google.com/maps?ll=%@", [latlong stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] ]] autorelease];
        [[UIApplication sharedApplication] openURL:url];
</code></pre>
