Need some advise about Instantiate/AddChild

[alexlange]

Hi guys
I'm going to build a embedded chat scene
---------------------------------------------------------
ScrollableMessages
      |---Message(prefab)
      |         |-- A Label and a sliced sprite
      |---Message(Clones)
---------------------------------------------------------
The program may call thousand times of NGUITools.AddChild().
Is AddChild equals to Instantiate? Will it cost too much?

Because I was told instantiate/destroy is very expensive,
and we'd better don't call it too many/often on mobile device.
People also suggest me to use a pool instead.

But I have no idea how to make it work with UITable/UIGrid :p

Yes, AddChild does an Instantiate call. I suggest you cache these instead. Enabling / disabling them (and/or reusing them) instead will have the same effect, but will be faster.
