在iOS中的GMSMapView上的两个位置之间绘制路线 [英] Drawing Route Between Two Places on GMSMapView in iOS

问题描述

我正在开发一个iOS应用程序。在那个应用程序中，我有2个来自和来自的字段。我使用Google Auto Complete API输入了地址，并且我能够获取2个位置的 Latitude 和经度，并且能够在 GMSMapView 。

现在我想绘制这两个地方之间的路线。当我们使用 MKMapView 时，我找到了一个解决方案。但我无法找到 GMSMapView 的解决方案。请帮助我在 GMSMapView 中绘制这两点之间的路线。如果可能的话，请给我一些重要的链接为此。

谢谢。

解决方案

 `首先获取路线中的所有点坐标，然后将这些点的经度和纬度添加到路径中，根据该路径绘制路径
 
 
 GMSCameraPosition * cameraPosition = [GMSCameraPosition cameraWithLatitude：18.5203​​经度：73.8567 zoom：12]; 
 _mapView = [GMSMapView mapWithFrame：CGRectZero camera：cameraPosition]; 
 _mapView.myLocationEnabled = YES; 
 GMSMarker * marker = [[GMSMarker alloc] init]; 
 marker.position = CLLocationCoordinate2DMake（18.5203​​，73.8567）; 
 marker.icon = [UIImage imageNamed：@aaa.png]; 
 marker.groundAnchor = CGPointMake（0.5,0.5）; 
 marker.map = _mapView; 
 GMSMutablePath * path = [GMSMutablePath path]; 
 [path addCoordinate：CLLocationCoordinate2DMake（@（18.520）.doubleValue，@（73.856）.doubleValue）]; 
 [path addCoordinate：CLLocationCoordinate2DMake（@（16.7）.doubleValue，@（73.8567）.doubleValue）]; 
 
 GMSPolyline * rectangle = [GMSPolyline polylineWithPath：path]; 
 rectangle.strokeWidth = 2.f; 
 rectangle.map = _mapView; 
 self.view = _mapView; 
  

I am Developing an iOS Application. In that Application i am having 2 Fields From and To. I Entered Address using Google Auto Complete API.and also i am able to Getting the Latitude and Longitude of the 2 places and able to show markers on the GMSMapView.

Now i Want to Draw Route Between these 2 Places. I found a solution when we use MKMapView. But i was Unable to find the solution for GMSMapView. please help me to Draw the route between these 2 points in GMSMapView.

If possible please give me some important links for this.

Thanks.

解决方案

`first get all points coordinates which are coming in route then add these points latitude and longitude in path in will draw path according to that`


GMSCameraPosition *cameraPosition=[GMSCameraPosition cameraWithLatitude:18.5203 longitude:73.8567 zoom:12];
_mapView =[GMSMapView mapWithFrame:CGRectZero camera:cameraPosition];
_mapView.myLocationEnabled=YES;
GMSMarker *marker=[[GMSMarker alloc]init];
marker.position=CLLocationCoordinate2DMake(18.5203, 73.8567);
marker.icon=[UIImage imageNamed:@"aaa.png"] ;
marker.groundAnchor=CGPointMake(0.5,0.5);
marker.map=_mapView;
GMSMutablePath *path = [GMSMutablePath path];   
[path addCoordinate:CLLocationCoordinate2DMake(@(18.520).doubleValue,@(73.856).doubleValue)];
[path addCoordinate:CLLocationCoordinate2DMake(@(16.7).doubleValue,@(73.8567).doubleValue)];

GMSPolyline *rectangle = [GMSPolyline polylineWithPath:path];
rectangle.strokeWidth = 2.f;
rectangle.map = _mapView;
self.view=_mapView;
