Now I want to add a static pin annotation on map in my iOS app.
But I just want to know if the delegate method mapView:viewForAnnotation: will be called.
In
Obviously MKMapView at least will call mapView:viewForAnnotation: when it will need to display your MKAnnotationView to the screen.
Whenever you call addAnnotation method - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id < MKAnnotation >)annotation gets called. Have look at the screenshot.

You can find this on MKMapView Class Reference
P.S. Put breakpoints at addAnnotation call and - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id < MKAnnotation >)annotation you will see the flow of function call easily.
