我试图从一个坐标到另一个坐标获得路线方向,但没有得到路线.下面提到用过的编码......

        NSArray *routesArray = [res objectForKey:@"routes"]; 
        NSDictionary *routeDict = [routesArray objectAtIndex:0];
        NSDictionary *routeOverviewPolyline = [routeDict objectForKey:@"overview_polyline"];
        NSString *points = [routeOverviewPolyline objectForKey:@"points"];
        GMSPath *path = [GMSPath pathFromEncodedPath:points];

        polyline = [GMSPolyline polylineWithPath:path];
        polyline.strokeColor = [UIColor greenColor];
        polyline.strokeWidth = 10.f;

        polyline.map = mapView_;

谁能知道.帮我解决这个问题..
