여기 선형 운동을위한 간단한 미디어 타이밍 애니메이션입니다 & UIView 댐핑 애니메이션.

참고 : 스위프트 4
extension UIView {
// Using CAMediaTimingFunction
func shake(duration: TimeInterval = 0.5, values: [CGFloat]) {
let animation = CAKeyframeAnimation(keyPath: "transform.translation.x")
animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)
animation.duration = duration // You can set fix duration
animation.values = values // You can set fix values here also
self.layer.add(animation, forKey: "shake")
}
// Using SpringWithDamping
func shake(duration: TimeInterval = 0.5, xValue: CGFloat = 12, yValue: CGFloat = 0) {
self.transform = CGAffineTransform(translationX: xValue, y: yValue)
UIView.animate(withDuration: duration, delay: 0, usingSpringWithDamping: 0.4, initialSpringVelocity: 1.0, options: .curveEaseInOut, animations: {
self.transform = CGAffineTransform.identity
}, completion: nil)
}
// Using CABasicAnimation
func shake(duration: TimeInterval = 0.05, shakeCount: Float = 6, xValue: CGFloat = 12, yValue: CGFloat = 0){
let animation = CABasicAnimation(keyPath: "position")
animation.duration = duration
animation.repeatCount = shakeCount
animation.autoreverses = true
animation.fromValue = NSValue(cgPoint: CGPoint(x: self.center.x - xValue, y: self.center.y - yValue))
animation.toValue = NSValue(cgPoint: CGPoint(x: self.center.x + xValue, y: self.center.y - yValue))
self.layer.add(animation, forKey: "shake")

}
버튼 동작
@IBAction func noButtonPressed(button: UIButton) {
//button.shake() // for spring damping animation
button.shake(duration: 0.5, values: [-12.0, 12.0, -12.0, 12.0, -6.0, 6.0, -3.0, 3.0, 0.0])
//button.shake(shakeCount: 10) // for CABasicAnimation
}
당신이 너무 GIF를 추가 할 수 있다면 정말 좋지 않을까 :) – Siyavash
