Here maps iOS SDK: Rotate the marker in Here maps

Question

I am working on a vehicle tracking app using Here maps. I want to rotate the marker icon (NMAMapMarker) in the Here maps to a specific angle according to turn taken by the vehicle (similar to Uber app). Earlier I used Google maps, marker in Google maps provides a rotation property to rotate the marker to a specific angle. Is there any similar property available in Here maps?

Is there any update for this Nokia Here maps Navigation marker orientation

Thank you

Answer 1

In general it is not possible to rotate NMAMapMarker, Within HERE iOS Premium SDK the default Position indicator NMAPositionIndicator has the property tracksCourse which would rotate the indicator with the heading available from device.

The alternative would be to use NMAMapLocalModel as also mentioned in the comments above

   ... 
   NMAFloatMesh *mesh = [[NMAFloatMesh alloc] init];

    float size = 5.0f;

    float vertices[4 * 3] = {-size / 2,   -size/2, 0.0f,
        -size/2,   size / 2, 0.0f,
        size / 2,   -size/2, 0.0f,
        size/2,   size/2, 0.0f,
    };

    [mesh setVertices:vertices withCount:4];

    float textureCoordinates[4 * 2] = {0.0,  0.0,
        0.0,  1.0,
        1.0,  0.0,
        1.0,  1.0};

    [mesh setTextureCoordinates:textureCoordinates withCount:4];

    short triangles[2 * 3] = {2, 1, 0,
        1, 2, 3};

    [mesh setTriangles:triangles withCount:2];

    _customPosIndicator = [[NMAMapLocalModel alloc] initWithMesh:mesh];

    NMAImage *image = [NMAImage imageWithUIImage:[UIImage imageNamed:@"256-256-pin2.png"]];

    /*
     // To load svg file as a custom position indicator, please use this code.
     NSBundle* main = [NSBundle mainBundle];
     NSString *resourcePath = [main pathForResource:@"tracker-1093167" ofType:@"svg"];

     NSLog(@"resourcePath: %@", resourcePath);
     NSData *resourceData = [NSData dataWithContentsOfFile:resourcePath];
     NMAImage *image = [NMAImage imageWithData:resourceData];
     */

    [_customPosIndicator setAutoscaled:true];
    [_customPosIndicator setTexture:image];
    [_customPosIndicator setCoordinates:[NMAGeoCoordinates alloc]];

    self.mapView.positionIndicator.displayObject = _customPosIndicator;

    self.mapView.positionIndicator.visible = true;

    ...

- (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(nonnull CLHeading *)newHeading {
    NSLog(@"%f", newHeading.magneticHeading);
    if(_customPosIndicator != nil){
        [_customPosIndicator setYaw:newHeading.magneticHeading];
    }
}
