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。
