MKAnnotationView and tap detection

Question

I have a MKMapView. I added a UITapGestureRecognizer with a single tap.

I now want to add a MKAnnotationView to the map. I can

Answer 1

Why not just add UITapGestureRecognazer in viewForAnnotation, use annotation's reuseIdentifier to identify which annotation it is, and in tapGestureRecognizer action method you can access that identifier.

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id)annotation {
    MKAnnotationView *ann = (MKAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:@"some id"];

    if (ann) {
        return ann;
    }

    ann = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"some id"];
    ann.enabled = YES;

    UITapGestureRecognizer *pinTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(pinTapped:)];
    [ann addGestureRecognizer:pinTap];
}

-(IBAction)pinTapped:(UITapGestureRecognizer *)sender {
    MKAnnotationView *pin = (MKPinAnnotationView *)sender.view;
    NSLog(@"Pin with id %@ tapped", pin.reuseIdentifier);
}
