Core Animation based on Quartz provides very simple ways to create special effects in your game or application.
The following shows how to create a Pulse Effect of any UIView (e.g. UIButtonView, UIImageView etc.)
- +(void)pulse:(UIView*)view toSize:(float) value withDuration:(float) duration
- {
- CABasicAnimation *pulseAnimation =[CABasicAnimation animationWithKeyPath:@"transform.scale"];
- pulseAnimation.duration = duration;
- pulseAnimation.toValue =[NSNumber numberWithFloat:value];;
