Find references of a sprite in atlas

[vnd3000]

Hi 

The thing is, my atlas is full and I need to remove some unused sprite to save space for new assets. But I don't know for sure that a sprite is unnecessary or not. Checking all objects in all scenes manually is boring and exhausting 

So, is there a quick way to get references count of a sprite in atlas (or something similar)?

Thanks in advanced

Unfortunately there is nothing like that in NGUI. You would need to write your own code to find all components of type UISprite and loop through them, comparing spriteName to what's in the atlas.
