NSPredicate question

I want to delete all annotations except RestaurantLocation or GrayRestaurantLocation.

is it correct version ?

[mapView removeAnnotations:[mapView.annotations 
    filteredArrayUsin开发者_如何学编程gPredicate:[NSPredicate predicateWithFormat:
       @"! ( (self isKindOfClass: %@) AND (self isKindOfClass: %@) )", 
      [RestaurantLocation class], [GrayRestaurantLocation class]]] ];

An annotation can't be both a RestaurantLocation AND a GrayRestaurantLocation.

Change the AND to OR.
