Dealloc object using iOS 5
I'm developing for iOS 5, say I have 2 arrays, the second only contains items contained on the first one.

I want to remove this object in every array it's present. I guess releasing the object would be a solution if I was using iOS 4 or before.

So, is there a way to easily remove an object from all arrays that contains it?
