Bug: UILabel or UISprite does not follow?

[usagi12]

Hi,
I want to know about the solution of the following problems.
I have been using the NGUI v2.2.6c in unity 3.5.6f4,
I confirmed that some objects UISprite, UILabel and placed under the GameObject that contains UIpanel does not follow the movement of the parent object.
This problem has been confirmed only in iOS.
I'm in trouble because there is no way to be sure you can reproduce this problem.
Does the same problem would have occurred in other cases?

Well, first you should upgrade to the latest version. I can only support the latest. Next, check the drag & drop example. If you reparented something yourself, you will want to call an appropriate function to let the widgets know.
