I cloned sprite ,but it don't have same transform with it's model gameobject.Why

[noob22]

I use "NGUITools.AddChild(Panel, Button);"
Panel is parent and Button is model gameobject.
Why a clone have a different transform with it's model gameobject?
How to clone a gameobject with the same transform by it's model gameobject?
And Suggestions?

NGUITools.AddChild clears the transform to 0 0 0.

NGUITools.AddChild clears the transform to 0 0 0.

I have got it！
GameObject g = NGUITools.AddChild(Panel, Button);
UISprite ui = g.GetComponent<UISprite>();
ui.MakePixelPerfect();
Thanks for your reply！
