我正在尝试在iOS上的谷歌地图中的两个地方之间创建路径。我可以使用以下代码在两个地方之间绘制路径。在这段代码中我使用谷歌地图键和放置键。当我接近点时，它即将到来，但是当我给v远点绘制路径时，根据谷歌地图，它并没有完美转动。

如果您使用的是Google地图，我会更喜欢这种方式。
GMSPolyline *polyPath = [GMSPolyline polylineWithPath:[GMSPath pathFromEncodedPath:encodedPath]];
以下是完整的代码段。
-(void)drawPathFrom:(CLLocation*)source toDestination:(CLLocation*)destination{
NSString *baseUrl = [NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/directions/json?origin=%f,%f&destination=%f,%f&sensor=true", source.coordinate.latitude, source.coordinate.longitude, destination.coordinate.latitude, destination.coordinate.longitude];
NSURL *url = [NSURL URLWithString:[baseUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSLog(@"Url: %@", url);
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
if(!connectionError){
NSDictionary *result = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSArray *routes = [result objectForKey:@"routes"];
NSDictionary *firstRoute = [routes objectAtIndex:0];
NSString *encodedPath = [firstRoute[@"overview_polyline"] objectForKey:@"points"];
GMSPolyline *polyPath = [GMSPolyline polylineWithPath:[GMSPath pathFromEncodedPath:encodedPath]];
polyPath.strokeColor = [UIColor redColor];
polyPath.strokeWidth = 3.5f;
polyPath.map = _mapView;
}
}];
}

如果要绘制两条路径BTW两个地方使用此方法。它的演示//MARK: API CALL
func GetRoughtofTwoLocation(){
let originString: String = "\(23.5800),\(72.5853)"
let destinationString: String = "\(24.5836),\(72.5853)"
let directionsAPI: String = "https://maps.googleapis.com/maps/api/directions/json?"
let directionsUrlString: String = "\(directionsAPI)&origin=\(originString)&destination=\(destinationString)&mode=driving"
APICall().callApiUsingWithFixURLGET(directionsUrlString, withLoader: true) { (responceData) -> Void in
let json = responceData as! NSDictionary
let routesArray: [AnyObject] = (json["routes"] as! [AnyObject])
var polyline: GMSPolyline? = nil
if routesArray.count > 0 {
let routeDict: [NSObject : AnyObject] = routesArray[0] as! [NSObject : AnyObject]
var routeOverviewPolyline: [NSObject : AnyObject] = (routeDict["overview_polyline"] as! [NSObject : AnyObject])
let points: String = (routeOverviewPolyline["points"] as! String)
let path: GMSPath = GMSPath(fromEncodedPath: points)!
polyline = GMSPolyline(path: path)
polyline!.strokeWidth = 2.0
polyline!.map = self.mapView
}
}
}
方法可以找到两个地方的溃败。
