Question

I want to preserve Ripple effect on my UIImageView. I know we can animate image for ripple effect , but preserve. In other words I want a rippled image.

I know we can animate image using

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:25.0];
[UIView setAnimationTransition:(UIViewAnimationTransition) 110 forView:imgRipple cache:NO]; 
[UIView commitAnimations];

But it animates , doesn’t keep the ripple. I think we can get rippled image if we Pause or Stop animation before it ends. Is it possible? how can we Pause or Stop UIView Animation?

If there is any alternate to this trick ,kindly mention it.

Thanks.

I got my solution,

used this code

CFTimeInterval pausedTime = [imgRipple.layer convertTime:CACurrentMediaTime() fromLayer:nil];
     imgRipple.layer.speed = 0.0;
     imgRipple.layer.timeOffset = pausedTime;

and it paused
