I looked over the SO, but strangely didn't find similar question. So the question is: If i have an entity called A and an entity called B, can B object have a property of type A? NOT relationship, but a property. I surely can use relationship as a property, but in my case i need an A object to have a property with type of A object. for example Entity called Human. And a property called child which is a Human too.
Human* parent=[Nsentity....bla bla
Human* child=parent.child;
Is there a way to do this not using transformable properties? I tried non-inverse relationship to self, but it rises a warning, and im like afraid that its gonna be a mess after all. cos in my case "parent" and "child" might be exactly the same object. so parent.child might be equal to parent
The is no prevention for "self" relationships.
An entity A may have a relation (one-to-one or one-to-many) with entity A or any of its descendants (or any other entity for that matter).
Define A like so (for one-to-one relationship):
parent (reltionship with inverse A->child)
child (relationship with inverse A->parent)
You probably don't want this to be a property as CoreData will not maintain it as part of the object graph (cascade rules and such).
