title: optimising tweenlite for IPhone Flash application
body: <p>I have an intro screen with a bitmap 250x130 that i want to fade in and out. 
  I am using tweenlite and it looks great on the Pc, but on the iphone, it looks
  like 1 or 2 fps, really slow.
  There is only 2 text fields and this animating Bitmap. The movie is set to the 
  default 24fps. the code is</p>
  
  <p>package  {</p>
  
  <pre><code>import flash.display.MovieClip;
  import com.greensock.TweenLite;
  import com.greensock.easing.*;
  
  public class intro extends MovieClip {
  
  
      public function intro() {
          fadesIn();
      }
  
      function fadesOut():void{ if (this.visible) TweenLite.to(mc, 4, {delay:1,ease:Cubic.easeInOut, alpha:0,onComplete:fadesIn});}
      function fadesIn():void{ if (this.visible) TweenLite.to(mc, 4, {delay:1,ease:Cubic.easeInOut, alpha:1,onComplete:fadesOut});}
  
  }
  </code></pre>
  
  <p>}</p>
