MKMapView calling didSelectAnnotationView

I use MKMapView. On map I show clickable AnnotationViews. After click on AnnotationView, I push MyController to NavigationController. In MyController I click on the back button, after this my previous controller is show (do pop controller). When I click on AnnotationVIew in my previousController callback didSelectAnnotationView does not rased. Why it happened?

Swift:

By Apple documentation (press Cmd + Click over the class name):

// Select or deselect a given annotation.  Asks the delegate for the corresponding annotation view if necessary.
public func selectAnnotation(annotation: MKAnnotation, animated: Bool)
public func deselectAnnotation(annotation: MKAnnotation?, animated: Bool)
public var selectedAnnotations: [MKAnnotation]

So after performing all the actions on the selected annotation call:

self.yourMapView.deselectAnnotation(yourAnnotation, animated: true)

Once we click on annotation it will call 

- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view

on clicking outside of annotation it should trigger 

- (void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view

but in my case i was overriding clicking outside annotation so i called method programmatically where ever needed:

[geoMapView deselectAnnotation:nil animated:NO];

As Oksana said: it's because the annotation view is selected and you should deselect it.

You can use : [_mapView selectAnnotation:nil animated:NO];

It because when I click on annotation it annotation selected and when I click on this annotation again it does not call callback didSelectAnnotationView, because this annotation already selected.

Check whether you have added MKMapViewDelegate in .h file and seted the delegate in .m file

 mapView.delegate = self;

And still if it will not work check didSelectAnnotationView is properly written or not.
