I am using google ios SDK to show direction in my app.I have plotted two points and shown info for corresponding points using folowing code.
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:9.96 longitude:76.31 zoom:12];
_mapView = [GMSMapView mapWithFrame:self.view.bounds camera:camera];
_mapView.myLocationEnabled = YES;
_mapView.delegate = self;
[self.view addSubview:_mapView];
_markerStart = [GMSMarker new];
_markerStart.title = @"Sreeni";
_markerStart.snippet=@"2Km";
_markerStart.icon = [GMSMarker markerImageWithColor:[UIColor greenColor]];
Now i want to show an info window to show distance between each points and an image of walking object.
