问题
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?
回答1:
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.
回答2:
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.

Swift 2.1:
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)
回答4:
As Oksana said: it's because the annotation view is selected and you should deselect it.
You can use : [_mapView selectAnnotation:nil animated:NO];
回答5:
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];
