NSPredicate问题

Question

我想删除除RestaurantLocation或GrayRestaurantLocation之外的所有注释。

是正确的版本吗？

[mapView removeAnnotations:[mapView.annotations 
    filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:
       @"! ( (self isKindOfClass: %@) AND (self isKindOfClass: %@) )", 
      [RestaurantLocation class], [GrayRestaurantLocation class]]] ];

Answer 1

注释不能同时是RestaurantLocation和GrayRestaurantLocation。

将AND更改为OR。
