todo：active和enable的差别？

核心API：

Component.GetComponentInChildren<Transform>()，应该是递归获取所有的child，激活的

GetComponentsInChildren<Transform>(true)，激活和未激活的都get

思路：获取Transform，然后在获取上面的GameObject。然后对child进行操作。

//img_bottomPanel_loading是Image		//GetComponentInChildren获取第一个child		Transform firstChild = img_bottomPanel_loading.GetComponentInChildren
     
       ();		string name = firstChild.gameObject.name;		Debug.Log ("firstChild:" + name);		//获取所有的children，		Transform[] children = img_bottomPanel_loading.GetComponentsInChildren
      
        ();		for (int i = 0; i < children.Length; i++) {			string nameTemp = children [i].gameObject.name;			children [i].gameObject.SetActive (false); //hide			Debug.Log ("nameTemp:" + nameTemp);		}
      
     

　

private void setBottomOperatePanelHide(bool hide){		img_bottomPanel_operate.enabled = !hide;		Transform[] children = img_bottomPanel_operate.GetComponentsInChildren
     
       (true);		foreach(Transform tr in children){			tr.gameObject.SetActive (hide);		}	}
