Quickly adding single pin to MKMapView?

Question

I have a GPS coordinate (latitude, longitude) and I quickly want to place a single pin on a MKMapView showing that position. Everything works just fine, but as I only need a single pin with no callout is there a quicker way to do this or is what I have below what needs to be done?

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id < MKAnnotation >)annotation {     MKPinAnnotationView *pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"DETAILPIN_ID"];     [pinView setAnimatesDrop:YES];     [pinView setCanShowCallout:NO];     return pinView; } 

NB: I don't need to check for reusable annotation views as I am only using the pin to show a position in a detail view (which is destroyed and recreated the next time a detail view is requested).

Answer 1

Instead of using the -mapView:viewForAnnotation: method, just put the code for an MKPointAnnotation into your -viewDidLoad method. It won't animate the drop, but it is very easy.

// Place a single pin MKPointAnnotation *annotation = [[MKPointAnnotation alloc] init]; [annotation setCoordinate:centerCoordinate]; [annotation setTitle:@"Title"]; //You can set the subtitle too [self.mapView addAnnotation:annotation]; 

Swift version:

let annotation = MKPointAnnotation() let centerCoordinate = CLLocationCoordinate2D(latitude: 41, longitude:29) annotation.coordinate = centerCoordinate annotation.title = "Title" mapView.addAnnotation(annotation) 

Answer 2

You can set the point and also the region like this:

CLLocationCoordinate2D coord = CLLocationCoordinate2DMake(lat, lon);  MKCoordinateSpan span = MKCoordinateSpanMake(0.1, 0.1); MKCoordinateRegion region = {coord, span};  MKPointAnnotation *annotation = [[MKPointAnnotation alloc] init]; [annotation setCoordinate:coord];  [self.staticMapView setRegion:region]; [self.staticMapView addAnnotation:annotation];
