Your question is why myView = nil doesn't remove the view from superview ( and so, why it doesn't deallocate it ).

This is quite simple, when you do viewA addSubview:viewB you create a reference from viewA to viewB.

So when you do viewB = nil, you still have a pointer from viewA to viewB so ARC doesn't release the view.

That's why you should call [viewB removeFromSuperview] to delete the pointer.

Please remove your view from super view before making it nil using [myView removeFromSuperView];
