需求

比如我想在添加Text时，自动添加一个脚本，用于处理多语言。在添加图片时，自动去掉raycast的勾选以节约性能损耗

解决方案

ObjectFactory.componentWasAdded 用于监听组件的添加事件

        ObjectFactory.componentWasAdded += ComponentWasAdded;
       
    }
    
    private static void ComponentWasAdded(Component com)
    {
        switch (com.GetType().ToString())
        {
            case "UnityEngine.UI.Image":
                ComponentOptimizing.OptimizingImage(com as Image);
                break;
            case "UnityEngine.UI.Text":
                ComponentOptimizing.OptimizingText(com as Text);
                break;
