觉得还可以,拿来收藏.
代码如下:
func shakeAnimation(view:UIView) {
let viewLayer = view.layer
let position = viewLayer.position
//移动的两个终点位置
let x = CGPointMake(position.x + 5, position.y)
let y = CGPointMake(position.x - 5, position.y)
//设置动画
let animation = CABasicAnimation(keyPath: "position")
//设置运动形式
animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionDefault)
//设置开始结束位置
animation.fromValue = NSValue.init(CGPoint: x)
animation.toValue = NSValue.init(CGPoint: y)
//设置自动反转
animation.autoreverses = true
animation.duration = 0.06
animation.repeatCount = 3
viewLayer.addAnimation(animation, forKey: nil)
}
