标题: 场景切换，unity异步加载，loading条做法
参考了网上大神的做法，做了一点小改动，效果还不错，给大家分享。

  AsyncOperation mAsync; //需要加载的场景
public UISlider LoadingSlider; //NGUI做的
public UILabel GameTip;

   // Use this for initialization
   void OnEnable()
   {
      StartCoroutine("LoadScene");

      GameTip.text = GameTipsController.Singleton.RandomTip();
   }

   void OnDisable()
   {
      StopAllCoroutines();
   }

   // Update is called once per frame
   void Update()
   {
   }

   IEnumerator LoadScene()
   {
      int displayProgress = 0;
      int toProgress = 0;
      mAsync = Application.LoadLevelAsync(StaticDataCache.Singleton.CurLoadScene);
      mAsync.allowSceneActivation = false;
      Debug.Log(mAsync.progress);
      while (mAsync.progress < 0.9f)
      {
         toProgress = (int)mAsync.progress * 100;
         while (displayProgress < toProgress)
         {
               ++displayProgress;
               SetLoadingSlider(displayProgress);
               yield return new WaitForEndOfFrame() ;
         }
         yield return new WaitForEndOfFrame();
      }

      toProgress = 100;
      while (displayProgress < toProgress)
      {
         ++displayProgress;
         SetLoadingSlider(displayProgress);
         yield return new WaitForEndOfFrame();
      }
      mAsync.allowSceneActivation = true;
      gameObject.SetActive(false);

   }

   void SetLoadingSlider(int progress)
   {
      float tmp = (float)((float)progress / 100);
      LoadingSlider.value = tmp;
   }
