Unity NGUI Tween Animation callback does not perform a problem

A problem has been encountered in recent work

Ngui's Tween animation completion callback function occasionally does not execute

I'm looking at the code now.

 tweenposition temptween = Vartar.getcomponent<tweenposition> ();  if  (Temptween = = null  " {Debuger.logerror (  " ma        Inuitaskaward:play () Temptween = = null   );     return  ;    } temptween.resettobeginning ();    Temptween.playforward ();        Eventdelegate.callback del  = delegate   () {  if  (temptween! = null  ) {Destroy (temptween.gameobject);    }    }; Temptween.setonfinished (del);  

I was first executed. Playforwar () after setfinished ()

The animation will appear when the card is finished, but there is no callback.

After modification

Tweenposition Temptween = vartar.getcomponent<tweenposition>(); if(Temptween = =NULL) {Debuger.logerror ("mainuitaskaward:play () Temptween = = NULL"); return; } eventdelegate.callback del=Delegate ()        {            if(Temptween! =NULL) {Destroy (temptween.gameobject);        }        };        Temptween.setonfinished (DEL);        Temptween.resettobeginning (); Temptween.playforward ();
