Hi all,

Let take you have two points, Point1 (In Boston) and Point2 (In Atlanta), Now you have to show the route between two points.

In below method , you have to pass two param's i.e.. two point of map.

- (void)displayRouteFrom:(CLLocationCoordinate2D)sourceCoordinate
                      to:(CLLocationCoordinate2D)destinationCoordinate
{
    MKDirectionsRequest *directionsRequest = [[MKDirectionsRequest alloc] init];
    directionsRequest.transportType = MKDirectionsTransportTypeAny;
    MKPlacemark *sourcePlacemark = [[MKPlacemark alloc] initWithCoordinate:sourceCoordinate
                                                         addressDictionary:nil];
    MKMapItem *sourceItem = [[MKMapItem alloc] initWithPlacemark:sourcePlacemark];

    MKPlacemark *destinationPlacemark = [[MKPlacemark alloc] initWithCoordinate:destinationCoordinate
                                                              addressDictionary:nil];
    MKMapItem *destinationItem = [[MKMapItem alloc] initWithPlacemark:destinationPlacemark];

    [directionsRequest setSource:sourceItem];
    [directionsRequest setDestination:destinationItem];
    directionsRequest.transportType = MKDirectionsTransportTypeAny;
    MKDirections *directions = [[MKDirections alloc] initWithRequest:directionsRequest];
    [self.indicatorIB startAnimating];
    [directions calculateDirectionsWithCompletionHandler:^(MKDirectionsResponse *response, NSError *error) {
        [self.indicatorIB stopAnimating];
        [self.indicatorIB setHidden:YES];
        if (error) {
            NSLog(@"Unable to find directions for the bus stop.");

//            [Utility showAlert:nil mess:@"Unable to find directions for the bus stop."];
        } else {
            MKRoute *routeDetails = response.routes.lastObject;

            [self.mapView setVisibleMapRect:[routeDetails.polyline boundingMapRect] edgePadding:UIEdgeInsetsMake(15.0, 15.0, 15.0, 15.0) animated:true];
            [self.mapView addOverlay:routeDetails.polyline];

        }
    }];
}

You can call above method like ->

 [self displayRouteFrom:CLLocationCoordinate2DMake([@"26354.267867" floatValue], [@"26354.267867" floatValue]) to:CLLocationCoordinate2DMake([@"26354.267867" floatValue], [@"26354.267867" floatValue])];
