How to add a custom view when tap on pin of map view?

I want to add a custom view in which I have four text field and five images with tap on pin of map view. I have use following code in .m file.

- (void)viewDidLoad
{
    [super viewDidLoad];

    appDelegate = (Yelp_OnTheWayAppDelegate *)[[UIApplication sharedApplication] delegate];
    self.title=@"Map";
    [aiv startAnimating]; 
    label.text=[NSString stringWithFormat:@"%d places along your route",[appDelegate.busines_Aray count]];
    [mapView setMapType:MKMapTypeStandard];
    [mapView setZoomEnabled:YES];
    [mapView setScrollEnabled:YES];
    [mapView setDelegate:self];
    MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };
    region.center.latitude = appDelegate.start_lat;
    region.center.longitude = appDelegate.start_long;
    region.span.longitudeDelta = 0.01f;
    region.span.latitudeDelta = 0.01f;  
    [mapView setRegion:region animated:YES];

    dm=[[DisplayMap alloc]init];
    for(int i=0;i<[Place_Object.aray_cord count];i++)
    {
        CLLocationCoordinate2D coord; 
        coord.latitude=[[Place_Object.aray_lat objectAtIndex:i] floatValue];
        coord.longitude=[[Place_Object.aray_long objectAtIndex:i] floatValue];
        dm=[[DisplayMap alloc]init];
        dm.coordinate=coord;
        dm.title=[appDelegate.lB objectAtIndex:i ];
        dm.pinID=i;
        [mapView addAnnotation:dm]; 
        NSLog(@"%@,%i at %f and %f",dm.title,dm.pinID,dm.coordinate.latitude,dm.coordinate.longitude);
    }
    routeOverlayView = [[UICRouteOverlayMapView alloc] initWithMapView:mapView];
    diretions = [UICGDirections sharedDirections];
    diretions.delegate = self;
    if (diretions.isInitialized)
    {
        [self update];
    }   
}

How add custom view on pin tap and how access my custom view class?

From here you will get a better guidance...

You can do the following things:

1. Create overlay for the MKMap
2. Draw on the over-layer your view.
3. Add animation for the custom view.
