title: How to give ripple effect on touch on a view in ipad application
body: <p>I want to use ripple effect on a specific area of view when the touch event happens.
  I used the following code:</p>
  
  <pre><code>CATransition *animation=[CATransition animation];
      [animation setDelegate:self];
      [animation setDuration:1.75];
      [animation setTimingFunction:UIViewAnimationCurveEaseInOut];
      [animation setType:@"rippleEffect"];
  
      [animation setFillMode:kCAFillModeRemoved];
      animation.endProgress=0.99;        
  
      [animation setRemovedOnCompletion:NO];
      [self.view.layer addAnimation:animation forKey:nil];
  </code></pre>
