您可以添加一个CAKeyframeAnimation
or CABasicAnimation
给你的marker.iconView!.layer
我们添加一个 UIView,其框架比我们的 UIImageView 更大,然后我们需要将 UIImageView 的锚点调整到底部垂直和水平居中,这将是我们动画中的枢轴点,我们的动画将是旋转Z 平面上的动画从 -30 到 30 等级以实现所需的动画。这是最简单的方法,但您也可以定义自定义类并制作很多其他东西
let marker = GMSMarker(position: CLLocationCoordinate2D(latitude: 22.404963, longitude: -79.961755))
//we need a bigger UIView to avoid the clip problem with the UIImageView
marker.iconView = UIView(frame: CGRect(x: 0, y: 0, width: 60, height: 40))
let imageView = UIImageView(frame: CGRect(x: (marker.iconView?.frame.width)!/2 - 14, y: (marker.iconView?.frame.height)! - 36, width: 28, height: 36))
imageView.contentMode = .scaleAspectFit
imageView.image = UIImage(named: "iconomapa")
marker.iconView?.addSubview(imageView)
imageView.layer.anchorPoint = CGPoint(x: 0.5, y: 1.0) //we need adjust anchor point to achieve the desired behavior
imageView.layer.frame = CGRect(x: (marker.iconView?.frame.width)!/2 - 14, y: (marker.iconView?.frame.height)! - 36, width: 28, height: 36) //we need adjust the layer frame
let animation = CAKeyframeAnimation()
animation.keyPath = "transform.rotation.z"
animation.values = [ 0, -30 * .pi / 180.0, 30 * .pi / 180.0 , 0]
animation.keyTimes = [0, 0.33 , 0.66 , 1]
animation.duration = 1;
animation.isAdditive = false;
animation.isRemovedOnCompletion = true
animation.repeatCount = .infinity
marker.iconView!.subviews[0].layer.add(animation, forKey: "shakeAnimation")
marker.map = self.mapView
这是它的样子
希望这可以帮助
