iPhone: Detecting Tap in MKMapView

Question

How do I detect a single tap on an instance of MKMapView? Do I have to subclass MKMapView and then override the touchesEnded method?

Thanks,

Answer 1

If you're just looking to get notified of tap gestures without affecting any of the other touch behavior of the map, you'll want to use a UITapGestureRecognizer. It's super simple, just put in some code like this.

UITapGestureRecognizer* tapRec = [[UITapGestureRecognizer alloc] 
   initWithTarget:self action:@selector(didTapMap:)];
[theMKMapView addGestureRecognizer:tapRec];
[tapRec release];

That will call the didTapMap whenever theMKMapView receives a tap gesture and all the pinching, and dragging gestures will still work as they did before.

Answer 3

Or depending on what you are trying to do, add an MKAnnotation (push pin, with a callout), so you have something to tap on - and then your map delegate will receive an event eg.

mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control

Working Perfectly on iOS 8

- (void)viewDidLoad 
    {
        [super viewDidLoad];

        UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:nil];
        doubleTap.numberOfTapsRequired = 2;
        doubleTap.numberOfTouchesRequired = 1;
        [self.mapView addGestureRecognizer:doubleTap];

        UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleGesture:)];
        singleTap.numberOfTapsRequired = 1;
        singleTap.numberOfTouchesRequired = 1;
        [singleTap requireGestureRecognizerToFail: doubleTap];
        [self.mapView addGestureRecognizer:singleTap];
     }

   - (void)handleGesture:(UIGestureRecognizer *)gestureRecognizer
     {
            if (gestureRecognizer.state != UIGestureRecognizerStateEnded)
                return;
            //Do your work ...
     }
