CAMediaTimingFunction自定义动画曲线
CAMediaTimingFunction.init(controlPoints: 0.63, 0.34, 1, 0.3)
//通过开始时间顺序执行
let caani = CABasicAnimation.init(keyPath: "transform.scale")
caani.fromValue = 0
caani.toValue = 1.03
caani.timingFunction = CAMediaTimingFunction.init(name: .linear)//init(controlPoints: 0.63, 0.34, 1, 0.3)
caani.duration = 1
self.v1.layer.add(caani, forKey: nil)
let caani2 = CABasicAnimation.init(keyPath: "transform.scale")
caani2.beginTime = CACurrentMediaTime() + 1//通过开始时间顺序执行
caani2.fromValue = 1.03
caani2.toValue = 1
caani2.timingFunction = CAMediaTimingFunction.init(name: .easeOut)
caani2.duration = 0.4
self.v1.layer.add(caani2, forKey: nil)
