i have made app on mapview. so just if you want get proper path you have to use KMLViewer or use GoogleMaps .In google Maps u can do this code

NSString *urlstring=[NSString stringWithFormat:@”http://maps.google.com/?saddr=%f,%f&daddr=

%f,%f”,sourcelocation.latitude,sourcelocation.longitude,destinationlocation.latitude,destin

ationlocation.longitude];

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlstring]];
