动画GMSMapView

Question

我尝试了谷歌地图提供的所有动画方法。但我无法为地图视图的缩放级别设置动画。我试过mapView.animateToZoom（15）。还

UIView.animateWithDuration(5.0, animations: {
                    let zoomIn = GMSCameraUpdate.zoomTo(15)
                    self.mapView.animateToZoom(15)
                })

但我没能实现动画。我也跟着GMSMapView animateToCameraPosition zoom in - zoom out animation

但没有希望。有人可以帮忙吗？

Answer 1

经过多次努力，我设法为GMSMapView设置了动画：以下是参考代码：

mapView.camera = GMSCameraPosition.cameraWithLatitude(58.998400,longitude: 10.035604, zoom: 1)


        CATransaction.begin()
        CATransaction.setValue(2.0, forKey: kCATransactionAnimationDuration)
        let city = GMSCameraPosition.cameraWithLatitude(58.998400,longitude: 10.035604, zoom: 15)
        self.mapView.animateToCameraPosition(city)
        CATransaction.commit()
