However, the page which i am able to push to is always only a view without any values passed into the labels. All my labels in the view have nothing inside.. Am i doing something wrong or any wrong concept here? </p> <pre><code>- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id &lt;MKAnnotation&gt;)annotation { BOOL isRed = NO; //BOOL isPurple = YES; if([annotation isKindOfClass:[MyAnnotation2 class]]) isRed = YES; MKPinAnnotationView *pinView = nil; if(isRed) { static NSString *redPin = @"redPin"; pinView = (MKPinAnnotationView *) [mapView dequeueReusableAnnotationViewWithIdentifier:redPin]; if (!pinView) { pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:redPin] autorelease]; pinView.pinColor = MKPinAnnotationColorRed; pinView.animatesDrop = YES; pinView.canShowCallout = YES; UIButton *detailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; pinView.rightCalloutAccessoryView = detailButton; } else{ pinView.annotation = annotation; } } else { static NSString *greenPin = @"greenPin"; pinView = (MKPinAnnotationView *) [mapView dequeueReusableAnnotationViewWithIdentifier:greenPin]; if (!pinView) { pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:greenPin] autorelease]; pinView.pinColor = MKPinAnnotationColorGreen; pinView.animatesDrop = NO; pinView.canShowCallout = YES; UIButton *detailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; pinView.rightCalloutAccessoryView = detailButton; } } return pinView; } </code></pre> <p>//</p> <pre><code>- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { NSLog(@"calloutAccessoryControlTapped"); if (self.patientDetailsViewController == nil) { self.patientDetailsViewController = [[[PatientDetailsViewController alloc] initWithNibName:@"PatientDetailsViewController" bundle:nil] autorelease]; } MyAnnotation2 *selectedObject = (MyAnnotation2 *)view.annotation; _patientDetailsViewController.nric = selectedObject.title; NSLog(@"%@",_patientDetailsViewController.nric); [self.navigationController pushViewController:_patientDetailsViewController animated:YES]; </code></pre> <p>}</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
