title: Is there a way to specify N control points for CAMediaTimingFunction?
body: <p>I am planning to have the <a href="https://developer.apple.com/documentation/quartzcore/cakeyframeanimation/1412522-keytimes" rel="nofollow noreferrer">keyTimes</a> functionality to my CAMediaTimingFunction.
  Here there are only 2 control points that can affect the animation curve. I want to be able to provide the keyTimes, which will act like a control points to form the curve. Is there a way to do it?</p>
