Unity 一键给所有按钮添加按钮音效

UGUI使用，NGUI需要稍微修改一点

                    AudioMgr.S.PlaySound(GameSound.EFFECT_CLICK_BTN);
                    break;
                case ButtonClickSound.Close:
                    AudioMgr.S.PlaySound(GameSound.EFFECT_CLOSE_BTN);
                    break;
            }
        }
        private void Awake()
        {
            Button btn = GetComponent();
            if (btn != null)
            {
                btn.onClick.AddListener(ClickSound);
            }
        }
    }
}

里面用到一些框架的功能，其实可以用你们自己代替 比如AddMissingComponent，Log.i其实就是Debug.Log,AudioMgr这些用自己的方法替代就好了。多余的引用自行删除即可。
