ios – UIDynamicAnimator具有d簧效果

概述我试图在这段代码中替换我的核心动画抖动效果 let shake = CAKeyframeAnimation(keyPath: "position.x") shake.values = [0, 20, -20, 20, -15, 15, -5, 5, 0] shake.keyTimes = [0, 1/10.0, 3/10.0, 5/10.0, 6/10.0, 7/10.0, 8/1 我试图在这段代码中替换我的核心动画抖动效果

let shake = CAKeyframeAnimation(keyPath: "position.x")    shake.values = [0,20,-20,-15,15,-5,5,0]    shake.keyTimes = [0,1/10.0,3/10.0,5/10.0,6/10.0,7/10.0,8/10.0,9/10.0,1]    shake.duration = 0.4    shake.additive = true    circlesContainer.layer.addAnimation(shake,forKey: "shakeYourBooty")

通过结合UIPushBehavior和UIAttachmentBehavior这样的d簧效果

if origCirclesContainerCenter == nil {        origCirclesContainerCenter = circlesContainer.center    }    shake = UIDynamicAnimator(referenceVIEw: self.vIEw)    let push = UIPushBehavior(items: [circlesContainer],mode: UIPushBehaviorMode.Continuous)    push.pushDirection = CGVectorMake(100.0,0.0)    print(origCirclesContainerCenter)    let attachement = UIAttachmentBehavior(item: circlesContainer,attachedToAnchor:origCirclesContainerCenter!)    attachement.frequency = 3.0    attachement.damPing = 0.5    shake.addBehavior(attachement)    shake.addBehavior(push)

问题是附件行为似乎不起作用,因为视图在被推动后不会d回到原始位置.动画实际上将视图位置推到右侧100点. origCirclesContainerCenter在每次通话时都是相同的.任何的想法？

解决方法 我将推送行为模式更改为UIPushBehaviorMode.Instantaneous以解决问题. 总结
