UIView, NSMutableArray and addSubview deallocation

Question

This question is related to a previous question of mine to which I couldn't get an answer, but I think I am getting closer.

I have a UIView , that is added to an NSMutableArray . Later I add that UIView as a subview of another view, but without removing it from the array . Does this mean that my UIView is no longer an item in my array?

In other words, does the -addSubview method automatically remove my UIView object from the NSMutableArray ?

Answer 1

No it doesn't. Your array and the superview to which you added the UIView will retain the view. That's all.

This can become a bit nasty if your UIView is unloaded due to a memory warning but is still in memory because of your array still retaining the instance.

Answer 2

No it does not. You have to explicitly remove it if you want it gone.

Answer 3

不，它应该仍然在数组内部。
