对象指针值作为字典的键 [英] Object pointer value as key into dictionary

问题描述

我想将对象的参考值用作字典中的键，而不是对象值的副本.因此，我本质上想将与另一个对象的特定实例相关联的对象存储在字典中，并在以后检索该值.

I want to use the object's reference value as a key into a dictionary, as opposed to a copy of value of the object. So, I essentially want to store an object associated with a particular instance of another object in a dictionary and retrieve that value later.

这可能吗?是否完全违背NSDictionary的想法?我可以说我可能采用了错误的方式，因为字典希望我在对象本身上实现NSCopying，这对我正在做的事情实际上没有任何意义.我可以看到我真正应该做的是包装指针值，但这似乎有点疯狂.

Is this possible? Is it completely against the idea of NSDictionary? I can tell that I am probably approaching this the wrong way because the dictionary wants me to implement NSCopying on the object itself, which doesn't really make sense in terms of what I'm doing. I can see that what I should really be doing is wrapping the pointer value, but that seems a little mad.

建议将不胜感激.

推荐答案

我认为您可以使用[NSValue valueWithPointer:object].
