I have set up a Core Data model that includes an entity, Item with a 1->M relationship with the abstract entity Place, so that an item has many places. There are several entities with the parent set to Place.

I want to set up several UI elements depending on the descendent place types. I have a loop that looks something like this:

for (Place *place in item.places) {

}

... but I'm not sure how to detect what type the place is, and how to cast it to the proper type so that I can access its properties.

Thanks for any help!
