title: UIbezierpath drawing with animation
body: <p>I need some suggestions regarding my one specific ipad project.In this project i have subclass of <code>UIview</code>  and there i have dawn several circles overriding <code>drawRect</code> method. Now i have also some semi rectangular <code>UIbezierpath</code> shape which need to be drawn with animation after i touch the circle. I was wondering what would be the easy way to draw this  <code>UIbezierpath</code> shape with animation.Do I need use 'NStimer' or call <code>setneedsdisplay</code> after touch each times.A help will be appreciated. Thanks in advance</p>
