<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><h1>使用 MapKit</h1>
<p>你需要让你的 <code></code>然后在 <code>response.routes</code> 你会得到可用的路线</p>
<blockquote>
<p>As is defined in <code>MKDirectionsRequest</code> declaration</p>
<p><code>open var requestsAlternateRoutes: Bool // if YES and there is more</code>
<code>than one reasonable way to route from source to destination, allow the</code>
<code>route server to return multiple routes. Default is NO.</code></p>
</blockquote>

MKDirectionsRequest * directionRequest = [init];
initWithPlacemark:[ initWithCoordinate:from]]];
initWithPlacemark:[ initWithCoordinate:destination]]];

MKDirections * directions = [ initWithRequest:directionRequest];
[directions calculateDirectionsWithCompletionHandler:^(MKDirectionsResponse * _Nullable response, NSError * _Nullable error) {

{
for (MKRoute * rute in response.routes) {
//DO WHAT YOU NEED WITH ROUTE
