Unity3D：UGUI遍歷子控件

參考文章：http://blog.csdn.net/u011185231/article/details/49591383

todo：active和enable的差別？

核心API：

Component.GetComponentInChildren<Transform>()，應該是遞歸獲取所有的child，激活的

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

思路：獲取Transform，然后在獲取上面的GameObject。然后對child進行操作。

		//img_bottomPanel_loading是Image
		//GetComponentInChildren獲取第一個child
		Transform firstChild = img_bottomPanel_loading.GetComponentInChildren<Transform> ();
		string name = firstChild.gameObject.name;
		Debug.Log ("firstChild:" + name);

		//獲取所有的children，
		Transform[] children = img_bottomPanel_loading.GetComponentsInChildren<Transform> ();
		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<Transform> (true);
		foreach(Transform tr in children){
			tr.gameObject.SetActive (hide);
		}
	}
