how to display guiTexture in NGUI

[1bol62pka90s02ga]

I has create gameobject and add script to camera but not show if in project I add UI of NGUI

void Start()
    {
for (int i = 0; i < maxLevel; i++)
        {
var obj = new GameObject("Block" + i);
            obj.AddComponent("GUITexture");
            obj.AddComponent("BlockDrag");
            obj.AddComponent("AudioSource");   
            obj.transform.localScale = Vector3.one;
listBlock.Add(obj);
}
}
void OnGUI(){

foreach (var x in listBlock)
        {           
            x.BlockObject.guiTexture.pixelInset = x.BlockRect;
            x.BlockObject.guiTexture.texture = GetBlockColorById(x.BlockColorId).Texture2D;
        }
    }

see my picture:
can anyone see where I am going wrong?

I don't understand why you try to display a GUITexture using NGUI, you should use UISprite instead.
If you absolutely want a GUITexture, ensure that it's on the same layer as the Camera (may be "UI" instead of "Default")

GUITexture and OnGUI != NGUI. You need to consult Unity's documentation instead.

They are two entirely different systems.  You can recreate what GUITexture does by using NGUI's UITexture.
