How to write gyroscope controller with Unity3d

Unity3d调用iOS接口播放视频，在视频播放完之后回到Unity3d场景时会出现世界颠倒的问题。

解决的方法是修改上述链接中附件中GyroController的代码，修改方法GetRotFix()，去掉#UNITY_3_5标签：

    private Quaternion GetRotFix()
    {
//#if UNITY_3_5
        if (Screen.orientation == ScreenOrientation.Portrait)
            return Quaternion.identity;

        if (Screen.orientation == ScreenOrientation.LandscapeLeft || Screen.orientation == ScreenOrientation.Landscape)
            return landscapeLeft;

        if (Screen.orientation == ScreenOrientation.LandscapeRight)
            return landscapeRight;

        if (Screen.orientation == ScreenOrientation.PortraitUpsideDown)
            return upsideDown;
        return Quaternion.identity;
//#else
//        return Quaternion.identity;
//#endif
    }

每帧进行判断，则可解决该问题。
