I had no idea how to set up a database when i started so i have 80 annotations that all look like this workingCoordinate.latitude = 50.795825; workingCoordinate.longitude = -1.103139; MainViewAnnotation *Levant = [[MainViewAnnotation alloc] initWithCoordinate:workingCoordinate]; [Levant setTitle:@"Levant"]; [Levant setSubtitle:@"Unit R09, Gunwharf Quays"]; [Levant setAnnotationType:MainViewAnnotationTypePortsmouth]; [mapView addAnnotation:Levant]; They are grouped into 22 cities through the MainViewAnnotationType, which is coded as follows: - (NSInteger)numberOfSectionsInTableView:(UITableView

I have added a MKUserTrackingBarButtonItem to my toolbar. But, clicking it does nothing. So, I assumed I need to use addTarget like a normal UIBarButtonItem but that doesn't work either. How can I attach a method to that button so that I can change setUserTrackingMode:animated: ? MKUserTrackingBarButtonItem *trackingItem = [[[MKUserTrackingBarButtonItem alloc] initWithMapView:mapView] autorelease]; UISegmentedControl *segmentedControl = [[[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"List", @"Detail", nil]] autorelease]; segmentedControl.frame = CGRectMake(0, 0, 220, 30)

- (void)viewDidLoad { [super viewDidLoad]; CLLocationCoordinate2D currentLocation; currentLocation.latitude = self.mapView.userLocation.location.coordinate.latitude; currentLocation.longitude = self.mapView.userLocation.location.coordinate.longitude; CLLocationCoordinate2D otherLocation; otherLocation.latitude = [lati doubleValue]; otherLocation.longitude = [longi doubleValue]; MKPointAnnotation *mka = [[MKPointAnnotation alloc]init]; mka.Coordinate = otherLocation; mka.title = @"!"; [self.mapView addAnnotation:mka]; self.mapView.delegate = self; MKMapPoint *pointsArray = malloc(sizeof

I'm having a problem finding out the way to update a custom MKAnnotationView image after a asynchronous request completes with information about the status of the annotation. So far, I have this: - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { static NSString *identifier = @"EstacionEB"; if ([annotation isKindOfClass:[EstacionEB class]]) { EstacionEB *location = (EstacionEB *) annotation; CustomPin *annotationView = (CustomPin *) [_mapita dequeueReusableAnnotationViewWithIdentifier:identifier]; if (annotationView == nil) { annotationView = [

I'm trying to display a polyline on my map, but the line doesn't show up. I tried a lot of things, but noting seems to work. I checked the Core Data functions, and it is returning data, so that is not the problem. It must me somewhere in the mappoint creation or the dwawing on the map (I guess). I'm sure it must be a little mistake somewhere, but I can't find it. My code: - (void)viewDidLoad { [super viewDidLoad]; AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; mapView.delegate = self; } - (void)createLine { AppDelegate *appDelegate = [[UIApplication sharedApplication]

I've created a mapview which has a button to switch between an 'edit' mode and a 'drag' mode based on the project requirements. I realize that it's easy enough to have your annotations draggable from creation by setting them draggable in the viewForAnnotation, but the behavior required won't allow this. I've tried a couple different ways of changing the annotations to draggable without success. The first thought was to loop through the existing annotations and set each one to 'draggable' and 'selected', but I get an unrecognized selector sent to instance error (I did try instantiating a new

I use this tutorial for integrating MapKit to my application: http://iphonebcit.wordpress.com/iphone-map-kit-tutorial/ CLLocationCoordinate2D coordinate; coordinate.latitude = 49.2802; coordinate.longitude = -123.1182; NSUInteger count = 1; for(int i = 0; i < 10; i++) { CGFloat latDelta = rand()*.035/RAND_MAX - .02; CGFloat longDelta = rand()*.03/RAND_MAX - .015; CLLocationCoordinate2D newCoord = {coordinate.latitude+latDelta, coordinate.longitude+longDelta}; MapDemoAnnotation* annotation = [[MapDemoAnnotation alloc] initWithCoordinate:newCoord andID:count++]; [mapView addAnnotation:annotation
