Select a position using draggable map and fixed ma

问题:

I'm newbie to iOS development and now trying to build a very simple navigation app using Google Maps SDK. So I created a map and centered it to current position of user.

Now I need to implement the following functionality:

• make a fixed marker that always remains in the center in a screen;
• let the user move the map, so the fixed marker will be pointed to desired position.
• to write coordinates of this position in some variable when user taps on marker.

Can someone please advice with some ideas how to achieve this, or with some sample code?

For the fixed marker, you can add a small UIButton on top of your map. After the user pans the map and taps your button, you can get the location centered in map

CLLocationCoordinate2D location = mapView.camera.target;
