If you want to show Direction in google maps you need current latitude & longitude and particular place lat & long,

Within Button touch action

 {          
  NSURL *strlist = [NSURL URLWithString:[NSString stringWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f",c_lat,c_long,lat,long]];
       here //c_lat = current latitude
  //c_long = current longitude
  //lat = Particular place latitude
  //long = Particular place longitude
 [[UIApplication sharedApplication]openURL:strlist];   
 }

If you want to show direction map within app,

Refer this tut

Something Similar ...

    //create new region and set map
    CLLocationCoordinate2D coord = {latitude: yourLocation.latitude, longitude: yourLocation.longitude};
     MKCoordinateSpan span = MKCoordinateSpanMake(fabs(otherLocation.lattitude), fabs(otherLocation.longitude));
    MKCoordinateRegion region = {coord, span};
    [self.mapView setRegion:region];
