How do I remove all annotations from MKMapView except the user location annotation?

by

Update:

When I tried with the iOS 9 SDK the user annotation is no longer removed. You can simply use

mapView.removeAnnotations(mapView.annotations)

Historical answer (for apps that run on iOS before iOS 9):

Try this:

NSMutableArray * annotationsToRemove = [ mapView.annotations mutableCopy ] ;
[ annotationsToRemove removeObject:mapView.userLocation ] ;
[ mapView removeAnnotations:annotationsToRemove ] ;

EDIT: Swift version

let annotationsToRemove = mapView.annotations.filter { $0 !== mapView.userLocation }
mapView.removeAnnotations( annotationsToRemove )
