title: How do I use a timing function within an animation on the iPhone?
body: <p>I want to use a timing function lets say kCAMediaTimingFunctionEaseInEaseOut</p>
  
  <p>My aim is I have start point (X1,Y1) and end point (X2,Y2) and I want a ease function which will provide the easing functionality over this points range. Like varying the (X,Y) range and giving me a curve from start to end.</p>
  
  <p>How to do that in iPhone.
  Like in the following article</p>
