Custom annotation view in Google Maps SDK

Question

I created an iOS application based on maps in which I thought to use Google Maps SDK for iOS instead of Mapkit, I found the documentation but it I didn’t find methods relate

Answer 1

If you check GMSMapView.h within GoogleMaps.Framework, you can see the below method which should let you add a custom infowindow for a marker, instead of using standard title and snippet alone:

NOTE you (op) say annotationView=infoWindow
BUT NORMAL: annotationView = marker itself and calloutView = infoWindow

/**
 * Called when a marker is about to become selected, and provides an optional
 * custom info window to use for that marker if this method returns a UIView.
 * If you change this view after this method is called, those changes will not
 * necessarily be reflected in the rendered version.
 *
 * The returned UIView must not have bounds greater than 500 points on either
 * dimension.  As there is only one info window shown at any time, the returned
 * view may be reused between other info windows.
 *
 * @return The custom info window for the specified marker, or nil for default
 */
- (UIView *)mapView:(GMSMapView *)mapView
    markerInfoWindow:(id)marker;
