I would like to have some kind of pulse animation (infinite loop "scale in - scale out") on a UIButton so it gets users' attention immediately.
I saw this link How to create a pulse effect using -web-kit animation - outward rings but I was wondering if there was any way to do this only using native framework?
Any help much appreciated - code sample even better ;-)
CABasicAnimation *theAnimation; theAnimation=[CABasicAnimation animationWithKeyPath:@"opacity"]; theAnimation.duration=1.0; theAnimation.repeatCount=HUGE_VALF; theAnimation.autoreverses=YES; theAnimation.fromValue=[NSNumber numberWithFloat:1.0]; theAnimation.toValue=[NSNumber numberWithFloat:0.0]; [theLayer addAnimation:theAnimation forKey:@"animateOpacity"]; //myButton.layer instead of
let pulseAnimation = CABasicAnimation(keyPath: "opacity") pulseAnimation.duration = 30 pulseAnimation.fromValue = 0 pulseAnimation.toValue = 1 pulseAnimation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut) pulseAnimation.autoreverses = true pulseAnimation.repeatCount = FLT_MAX self.view.layer.addAnimation(pulseAnimation, forKey: nil)
