Title Body

I've got a MKMapView and I'm adding annotations like this: for (NSDictionary *tmp in response) { NSDictionary *places = [tmp objectForKey:@"place"]; NSDictionary *location = [places objectForKey:@"location"]; NSLog(@"long: %@ Lat:%@",[location objectForKey:@"longitude"], [location objectForKey:@"latitude"]); float longitude = [[location objectForKey:@"longitude"] floatValue]; float latitude = [[location objectForKey:@"latitude"] floatValue]; CLLocationCoordinate2D locationco = {latitude,longitude}; NSString *titleString = [tmp objectForKey:@"name"]; Place *pin = [[Place alloc] init]; pin.coordinate = locationco; pin.title = titleString; pin.subtitle = @"A Location"; //NSArray *annots = [[NSArray alloc] initWithObjects:pin, nil]; //[map addAnnotations:annots]; [map addAnnotation:pin]; [[map viewForAnnotation:pin] setCanShowCallout:YES]; } The MKAnnotation 's show up on the map fine, and I can select them, however no callout bubble appears. I know that they are being selected properly form this -(void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view { [view setCanShowCallout:YES]; NSLog(@"Title:%@",[view.annotation description]); } But that just prints out Title:(null) I'm using ARC, and I've got the properties set up in my Place object as such: @property (nonatomic) CLLocationCoordinate2D coordinate; @property (nonatomic,readwrite, copy) NSString *title; @property (nonatomic,readwrite, copy) NSString *subtitle; What am I doing wrong/missing? Thanks.
