关于unity:利用反射机制给View面板脚本里的组件字段赋值

 当 UI 脚本上须要赋值的组件太多的时候，利用反射机制主动给参数赋值就显得很不便。只须要参数名称和 UI 节点的名称相一致 (能够定义本人的匹配规定)

    /// <summary>
    /// 给字段赋值
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="root"></param>
    /// <param name="tObj"></param>
    public static void SetFieldValue<T>(this Transform root,T tObj)
    {var fields = typeof(T).GetFields(BindingFlags.Instance | BindingFlags.NonPublic)?.Where(p => p.FieldType.IsSubclassOf(typeof(Component))).ToList();
        RecursiveSetValue(root, fields, tObj);
    }

    /// <summary>
    /// 递归函数给类里的字段赋值
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="root"></param>
    /// <param name="fieldInfos"></param>
    /// <param name="tObj"></param>
    private static void RecursiveSetValue<T>(Transform root,List<FieldInfo> fieldInfos,T tObj)
    {if (fieldInfos == null || fieldInfos.Count == 0) return;

        for (int i = 0; i < root.childCount; i++)
        {var child = root.GetChild(i);
            RecursiveSetValue(child, fieldInfos,tObj);
            for (int j = fieldInfos.Count - 1; j >= 0; j--)
            {var fieldInfo = fieldInfos[j];
                if (fieldInfo.FieldType.IsSubclassOf(typeof(Component)) && fieldInfo.Name.IsMatch(child.name))
                {var component = child.GetComponent(fieldInfo.FieldType);
                    fieldInfo.SetValue(tObj, component);
                    fieldInfos.RemoveAt(j);
                }
            }
        }
    }

    /// <summary>
    /// 判断字段的名称和节点的名称是否匹配
    /// </summary>
    /// <param name="name"></param>
    /// <param name="transName"></param>
    /// <returns></returns>
    private static bool IsMatch(this string name,string transName)
    {var temp = name.StartsWith("_") ? name.Substring(1, name.Length - 1) : name;
        return temp.ToLower().Equals(transName.ToLower());
    }
