title: Prevent touch events on MKMapView being detected when a MKAnnotation is tapped
body: <p>I have a UITapGestureRecognizer that will hide and show a toolbar over my MKMap when the user taps the Map - simple.</p>
  
  <p>However, when the user taps on an MKMapAnnotation, I do not want the map to respond to a tap in the normal way (above). Additionally, when the user taps elsewhere on the map to de-select an MKAnnotation callout, I also don't want the toolbar to respond. So, the toolbar should only respond when there are no MKAnnotations currently in selected state. Nor should it respond when the user clicks on an annotation directly.</p>
  
  <p>So far, I have being trying the following action that reacts to the tap gesture on the map - however the Annotation View is never detected (the first if statement) and also, the annotation view is also launched regardless of this method. </p>
  
  <pre><code> -(void)mapViewTapped:(UITapGestureRecognizer *)tgr
  {
      CGPoint p = [tgr locationInView:self.mapView];
  
      UIView *v = [self.mapView hitTest:p withEvent:nil];
  
      id&lt;MKAnnotation&gt; ann = nil;
  
      if ([v isKindOfClass:[MKAnnotationView class]])&lt;---- THIS CONDITION IS NEVER MET BUT ANNOTATIONS ARE SELECTED ANYWAY
      {
          //annotation view was tapped, select it…
          ann = ((AircraftAnnotationView *)v).annotation;
          [self.mapView selectAnnotation:ann animated:YES];
      }
      else
      {
  
          //annotation view was not tapped, deselect if some ann is selected...
          if (self.mapView.selectedAnnotations.count != 0)
          {
              ann = [self.mapView.selectedAnnotations objectAtIndex:0];
              [self.mapView deselectAnnotation:ann animated:YES];
          }
  
          // If no annotation view is selected currently then assume control of
          // the navigation bar.
          else{
  
              [self showToolBar:self.navigationController.toolbar.hidden];
          }
      }
  }
  </code></pre>
  
  <p>I need to control the launch of the annotation call out programmatically and detect when the tap event has hit an annotation in order to achieve this.</p>
  
  <p>Any help would be appreciated.</p>
