UIPackage.AddPackage自定义加载问题

 byte[] desc = LoadByteByIO(packName + ".fui.bytes");

FairyGUI.UIPackage.AddPackage(desc, string.Empty, (string name, string extension, System.Type type) =>

 {

     if (extension == ".bytes")

     {

         return new TextAsset(Encoding.UTF8.GetString(LoadByteByIO(name + extension)));

     }

     else if (extension == ".png")

     {

         return LoadTexture2DByIO(packName + "_" + name + extension);

     }



     return null;

 });

//在NTexture的Unload方法卸载的时候

//destroyMethod=DestroyMethod.Unload

//会走Resources.UnloadAsset(_nativeTexture);

//但是由于这个不是由AssetDatabase或者Resources加载的，所以会报错

UnloadAsset can only be used on assets;
