我想删除除RestaurantLocation或GrayRestaurantLocation之外的所有批注。
它的版本正确吗？
[mapView removeAnnotations:[mapView.annotations
filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:
@"! ( (self isKindOfClass: %@) AND (self isKindOfClass: %@) )",
[RestaurantLocation class], [GrayRestaurantLocation class]]] ];
注释不能同时是RestaurantLocation和GrayRestaurantLocation。
将AND更改为OR。
