据我了解你的问题，我提出这个解决方案，其中我在两个地点之间画了一个polly直播，一旦用户点击该汽车注释汽车注释将在路径上运行，就像超级一样。

As far as I understood your question I am proposing this solution in which i have drawn a polly live between two locations, Once user tap on that car annotation car annotation will run on path same like uber.

您可以通过自定义方法moveCar（_ destinationCoordinate：CLLocationCoordinate2D）并传递从服务器获取的坐标的最新值来为自定义注释设置动画。

You can animate your custom annotation by making custom method  moveCar(_ destinationCoordinate : CLLocationCoordinate2D) and  passing latest value of coordinate which you are getting from server.
