NGUI Sprire not visible in 3d when added by code

[alexKhvorov]

As above

When i add them by hand its nice two-sided GO with sprites, but when i do this by code

1.             GameObject squadUnit = new GameObject("squadUnit"+i);
2.                         UISprite uiSpr = squadUnit.AddComponent<UISprite>();
3.                         uiSpr.atlas = atlas;
4.                         uiSpr.spriteName = "frame2";
5.                         uiSpr.panel = uiPanel;
6.                         squadUnit.transform.parent = panel.transform;
7.                         UISpriteAnimation uiSprAnim = squadUnit.AddComponent<UISpriteAnimation>();
8.                         uiSprAnim.framesPerSecond = 8;
9.                         uiSprAnim.namePrefix = "frame";
10.  

I see a rectangles but animation frames not visible
How to add them properly?

You need to use NGUITools.AddChild<UISprite>(parent), not new GameObject/AddComponent. You never set the layer, which is your problem.
