    <p>the situation is following, i am running xCode 4.1 on MacOS 10.7, starting iPhone simulator and using MapKit am trying to get <strong>REAL</strong> user's coordinates ... default user's location is in Cupertino, USA ... to get cordinates of this point i use :</p> <pre><code>self.mapView.userLocation.location.coordinate </code></pre> <p>... but this gets me to the center of the map (in Africa) ... </p> <p><strong>Question #1 :</strong> Why??? Why user's pin is set to Cupertino but its coordinates are (lat:0, lon:0) in Africa?</p> <p>... then ... </p> <p>I have setup my controller as CCLocationManagerDelegate and MKMapViewdelegate and initialized controller as delegate for CCLocationManagerDelegate's events ... but neither of these delegate methods was called ... </p> <pre><code>- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id&lt;MKAnnotation&gt;)annotation - (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation </code></pre> <p><strong>Question #2 :</strong> Why delegate methods are not triggered even once?</p> <p>My controller : </p> <pre><code>//@interface MapController : UIViewController&lt;CLLocationManagerDelegate, MKMapViewDelegate&gt; //@property (nonatomic, retain) MapModel *mapModel; //@property (nonatomic, retain) IBOutlet MKMapView *mapView; - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { ... } - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id&lt;MKAnnotation&gt;)annotation { ... } - (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation { ... } - (void)viewDidLoad { [super viewDidLoad]; self.mapModel = [[[MapModel alloc] init:self] autorelease]; [self.mapView setShowsUserLocation:YES]; [self.mapView setZoomEnabled:YES]; [self.mapView setScrollEnabled:YES]; [self.mapView setMapType:MKMapTypeStandard]; CLLocationCoordinate2D x = self.mapView.userLocation.location.coordinate; // (0,0) why??? //[self.mapView setRegion:xx animated:YES]; //[self.mapView regionThatFits:self.mapModel.region]; [[self.mapView userLocation] setCoordinate:[x coordinate]]; } ... </code></pre> <p>And model :</p> <pre><code> //@property (nonatomic, copy) NSString *user; //@property (nonatomic, copy) NSString *caption; //@property (nonatomic, copy) NSString *description; //@property (nonatomic, assign) MKCoordinateRegion region; //@property (nonatomic, retain) CLLocationManager *manager; - (id)init :(id)delegate { self.manager = [[[CLLocationManager alloc] init] autorelease]; self.manager.delegate = delegate; self.manager.distanceFilter = kCLDistanceFilterNone; self.manager.desiredAccuracy = kCLLocationAccuracyHundredMeters; [self.manager startUpdatingLocation]; MKCoordinateRegion region = {{0, 0}, {0.2, 0.2}}; self.region = region; return self; } </code></pre> <p>Thanks, Art</p>

    1. COif `self.mapView.userLocation.location.coordinate` gives you 0,0 it is probably because mapView or userLocation or location is a nil pointer.

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.
