SingleTapOnMap method not calling in iphone - ios

Question

I am using below piece of code using to interact with MBTiles. But singleTapOnMap method is not calling when i run it on iphone. I also added Trailer which is working on TileMill, but not on iPhone. Whether i have gone wrong anywhere?
//ViewController.h
#interface ViewController : UIViewController<RMMapViewDelegate>
#end
//ViewController.m
- (void)viewDidLoad
{
RMMBTilesSource *offlineSource = [[RMMBTilesSource alloc] initWithTileSetResource:#"MYMAP" ofType:#"mbtiles"];
RMMapView *mapView = [[RMMapView alloc] initWithFrame:self.view.bounds andTilesource:offlineSource];
mapView.zoom = 2;
mapView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
mapView.adjustTilesForRetinaDisplay = YES; // these tiles aren't designed specifically for retina, so make them legible
[self.view addSubview:mapView];
}
#pragma mark -
- (void)singleTapOnMap:(RMMapView *)mapView at:(CGPoint)point
{
[mapView removeAllAnnotations];
RMMapBoxSource *source = (RMMapBoxSource *)mapView.tileSource;
NSLog(#"You tapped at %f, %f", [mapView pixelToCoordinate:point].latitude, [mapView pixelToCoordinate:point].longitude);
if ([source conformsToProtocol:#protocol(RMInteractiveSource)] && [source supportsInteractivity])
{
NSString *formattedOutput = [source formattedOutputOfType:RMInteractiveSourceOutputTypeTeaser
forPoint:point
inMapView:mapView];
if (formattedOutput && [formattedOutput length])
{
// parse the country name out of the content
//
NSUInteger startOfCountryName = [formattedOutput rangeOfString:#"<strong>"].location + [#"<strong>" length];
NSUInteger endOfCountryName = [formattedOutput rangeOfString:#"</strong>"].location;
NSString *countryName = [formattedOutput substringWithRange:NSMakeRange(startOfCountryName, endOfCountryName - startOfCountryName)];
// parse the flag image out of the content
//
NSUInteger startOfFlagImage = [formattedOutput rangeOfString:#"base64,"].location + [#"base64," length];
NSUInteger endOfFlagImage = [formattedOutput rangeOfString:#"\" style"].location;
UIImage *flagImage = [UIImage imageWithData:[NSData dataFromBase64String:[formattedOutput substringWithRange:NSMakeRange(startOfFlagImage, endOfFlagImage)]]];
RMAnnotation *annotation = [RMAnnotation annotationWithMapView:mapView coordinate:[mapView pixelToCoordinate:point] andTitle:countryName];
annotation.userInfo = flagImage;
[mapView addAnnotation:annotation];
[mapView selectAnnotation:annotation animated:YES];
}
}
}
- (RMMapLayer *)mapView:(RMMapView *)mapView layerForAnnotation:(RMAnnotation *)annotation
{
RMMarker *marker = [[RMMarker alloc] initWithMapBoxMarkerImage:#"embassy"];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 50, 32)];
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.image = annotation.userInfo;
marker.leftCalloutAccessoryView = imageView;
marker.canShowCallout = YES;
return marker;

You have to assign the delegate protocol:
mapView.delegate = self;
