MKAnnotationView not displaying the title

Question

I am setting the title for two MKAnnotationView using the following code:

-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:
(id <MKAnnotation>)annotation 
{

if(([annotation isKindOfClass:[Test_flag class]])) 
{

    MKAnnotationView *pinView = nil; 

    if(annotation != mapView.userLocation) 
    {
        static NSString *defaultPinID = @"PinId1";
        pinView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
        if ( pinView == nil ) pinView = [[[MKAnnotationView alloc]
                                          initWithAnnotation:annotation reuseIdentifier:@"pin1"] autorelease];
        pinView.canShowCallout = YES;
        pinView.animatesDrop = YES;
        [pinView setImage:[UIImage imageNamed:@"flg.png"]];
        [pinView setSelected:YES animated:YES];

    } 
    else 
    {
        [mapView.userLocation setTitle:@"I am here"];
    }
    return pinView;
}
else if(([annotation isKindOfClass:[Distance1 class]])) 
{
    MKAnnotationView *pinView = nil; 

    if(annotation != mapView.userLocation) 
    {
        static NSString *defaultPinID = @"PinId4";
        pinView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
        if ( pinView == nil ) pinView = [[[MKAnnotationView alloc]
                                          initWithAnnotation:annotation reuseIdentifier:@"pin4"] autorelease];

        pinView.canShowCallout = YES;
        [pinView setImage:[UIImage imageNamed:@"Circle_Grey.png"]];
        [pinView setSelected:YES animated:YES];

    } 
    else 
    {
        [mapView.userLocation setTitle:@"I am here"];
    }
    return pinView;
}

When I touch the map, both MKAnnotationView are pointed but they do not show the title. What is the reason? Please help me to find.

You missed to write title method in Test_flag class.

I have added NSString *title and @property,@synthesize also in Test_flag class – Madhumitha Aug 23 '12 at 08:08
When you are adding annotation to the map, set the value to title. For now hardcode return temp value to check. – Apurv Aug 23 '12 at 08:11
that also I did like test_flag.title = @"Distance"; test_flag.subtitle = @"0.0"; – Madhumitha Aug 23 '12 at 08:15
Display the code from where you are adding annotations to the map. – Apurv Aug 23 '12 at 08:16
Test_flag *test_flag = [[Test_flag alloc] init]; test_flag.title = @"Distance"; test_flag.subtitle = @"0.0"; [mapView addAnnotation:test_flag]; after that am setting the coordinate like test_flag.coordinate = CLLocationCoordinate2DMake(28.458586, 77.109126); – Madhumitha Aug 23 '12 at 08:27
