Not worth worrying about. Unless your states are immensely complicated, or you have thousands and thousands of them, then any art or media files that are in your application will absolutely swamp them in size.
I mean in general - don't sweat the memory usage of your model objects. Objective-C objects are pretty lightweight, in terms of memory usage. If you've got a fairly typical model class, with say a half-dozen fields, each of which is a pointer to some other object, the total memory usage for each instance of that class is something like 32 bytes or so. If you put 1,000 of them into an array or some other data structure, that'd use about as much memory as a 128x128 bitmap.
You're much more likely to run into memory issues due to hanging on to graphics or sounds that you don't need to, than you ever will from the "working" parts of your application.

不值得担心。 除非您的状态非常复杂，或者您有成千上万个状态，否则应用程序中的任何艺术或媒体文件绝对会淹没它们的大小。
我的意思是一般来说 - 不要担心模型对象的内存使用情况。 就内存使用而言，Objective-C 对象相当轻量。 如果您有一个相当典型的模型类，其中有六个字段，每个字段都是指向其他对象的指针，则该类的每个实例的总内存使用量约为 32 个字节左右。 如果将其中 1,000 个放入数组或其他数据结构中，则使用的内存大约与 128x128 位图一样多。
与应用程序的“工作”部分相比，由于保留不需要的图形或声音，您更有可能遇到内存问题。
