I want to use my class as a property in my project. The idea is that i have a class which contains all list ellements. The basic idea i show below in graph:![enter image description here](https://i.stack.imgur.com/g8IGv.jpg)
So i have a myContainerClass object, and i want to do in some other class:
@property (strong,nonatomic) MyContainerClass \*obj;
and here i have error! I figure out that i can only use Foundations type as a @property. But Why? What is replacement for doing that (passing an object)?
