I’m engaged on an iOS app the place I have to create ripple impact on a UIView. I’m able to create the ripple impact however I’m not capable of customise it. That is what I wish to achive:
That is my present output
What I wish to obtain is create 4-5 ripples repeatedly after which after some delay one other 4-5 ripple and repeat the method infinitely. However at the moment I’m solely capable of create 1 ripple (it does go infinitely).
Right here is my code:
func addRipple(rView: UIView) {
let path = UIBezierPath(ovalIn: CGRect(x: 0, y: 0, width: rView.bounds.dimension.width, top: rView.bounds.dimension.top))
let shapePosition = CGPoint(x: rView.bounds.dimension.width / 2.0, y: rView.bounds.dimension.top / 2.0)
let rippleShape = CAShapeLayer()
rippleShape.bounds = CGRect(x: 0, y: 0, width: rView.bounds.dimension.width, top: rView.bounds.dimension.top)
rippleShape.path = path.cgPath
rippleShape.fillColor = UIColor.clear.cgColor
rippleShape.strokeColor = UIColor.systemBlue.cgColor
rippleShape.lineWidth = 1
rippleShape.place = shapePosition
rippleShape.opacity = 0
rView.layer.addSublayer(rippleShape)
let scaleAnim = CABasicAnimation(keyPath: "remodel.scale")
scaleAnim.fromValue = NSValue(caTransform3D: CATransform3DIdentity)
scaleAnim.toValue = NSValue(caTransform3D: CATransform3DMakeScale(2, 2, 1))
let opacityAnim = CABasicAnimation(keyPath: "opacity")
opacityAnim.fromValue = 1
opacityAnim.toValue = nil
let animation = CAAnimationGroup()
animation.animations = [scaleAnim, opacityAnim]
animation.timingFunction = CAMediaTimingFunction(title: CAMediaTimingFunctionName.easeOut)
animation.period = 1
animation.repeatCount = Float.infinity
animation.isRemovedOnCompletion = false
rippleShape.add(animation, forKey: "rippleEffect")
}
I feel I’m very shut however I’m not capable of determine it out.
Thanks prematurely.
