Does the meterials of UITexture destroyed by itself when gameObject destroyed?

[pengyingh]

I remembered the meterials need to be destroyed separately，or will cause memory leak,but I haven‘t tested it.

I got the same problem. Memory leak because materials don't be destroyed when destroyed game object. Is there anyone come up with any ideas to solve it?

UITexture has this:

1. void OnDestroy () { NGUITools.Destroy(mDynamicMat); }
