    <p>Suppose I have the code below to add a map on a view, what is the <strong>simplest</strong> way to add a <strong>pin</strong> on the location. Could someone advise the code snippet to add to my code?</p> <p>Thanks</p> <pre><code>- (void)viewDidLoad { MKMapView *map = [[MKMapView alloc] initWithFrame:CGRectMake(2, 2, 300, 300)]; MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center.latitude = 22.278355; region.center.longitude = 114.181713; region.span.longitudeDelta = 0.01f; region.span.latitudeDelta = 0.01f; [map setRegion:region animated:YES]; [map regionThatFits:region]; [self.view addSubview:map]; [super viewDidLoad]; // Do any additional setup after loading the view from its nib. } </code></pre> <p>UPDATE: </p> <p>xxx.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import &lt;MapKit/MapKit.h&gt; @interface ShopDetail : UIViewController &lt;MKMapViewDelegate&gt; { } @end </code></pre> <p>xxx.m</p> <pre><code>- (void)viewDidLoad { MKMapView *map = [[MKMapView alloc] initWithFrame:CGRectMake(2, 2, 300, 300)]; MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center.latitude = 22.278355; //40.105085; region.center.longitude = 114.181713; //-83.005237; region.span.longitudeDelta = 0.01f; region.span.latitudeDelta = 0.01f; [map setRegion:region animated:YES]; [map regionThatFits:region]; map.delegate = self; [self.view addSubview:map]; [super viewDidLoad]; // Do any additional setup after loading the view from its nib. } - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id &lt;MKAnnotation&gt;)annotation { MKPinAnnotationView *pav = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:nil]; NSLog(@"called viewForAnnotation"); pav.pinColor = MKPinAnnotationColorGreen; return pav; } </code></pre> <p>*NSLog(@"called viewForAnnotation"); has not been executing.</p>

    1. COUpdate didn't seem to work for me, even though I just copied your code. Are you sure the delegate is firing the Annotation?

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.
