(斯威夫特4(

let polyline = GMSPolyline(path: GMSPath(fromEncodedPath:polylineString))

如何将相机动画化到这条折线？

Answer 1

您需要读取折线的第一个和最后一个坐标，并以这种方式对摄像机移动进行动画处理。

let vancouver = CLLocationCoordinate2D(latitude: 49.26, longitude: -123.11)
let calgary = CLLocationCoordinate2D(latitude: 51.05,longitude: -114.05)
let bounds = GMSCoordinateBounds(coordinate: vancouver, coordinate: calgary)
let camera = mapView.camera(for: bounds, insets: UIEdgeInsets())!
mapView.camera = camera
