HowTo detect tap on map annotaition Pin?

I want to detect tap on annotation pin(of mapkit) so that I can perform action on that event.

Now the default annotation flag pops up in case I touch the annotation pin. I want to customise that to call my method when pin is touched.

Solution


  • You need to implement the following delegate method 

     (MKAnnotationView) mapView viewForAnnotation:(id) annotation

    Then just declare following in this method 

    MKPinAnnotationView *view=[[MKPinAnnotationView alloc]initWithAnnotation:annotation  reuseIdentifier:@"abc"];
view.canShowCallout=YES;
view.calloutOffset=CGPointMake(-20,10); //As per your choice

    Then you can add UI to your callout eg UIButton or UIImage as view.rightCalloutAccesoryView View.leftCalloutAccesoryView
