I am trying to show a custom overlay view from the Google Maps through the Google Maps API for iOS. This overlay view content info of marker, and two my button. But I cannot find any references for this. My desired overlay view is as image with link below:

Please give me a guide for this!
The best way of achieving this is to pass your GMSMapView a custom view for your info windows via the GMSMapViewDelegate's mapView:markerInfoWindow: method.
To accomplish this, set yourself up as the delegate for your GMSMapView instance, like so:
self.mapView.delegate = self;
Then return a custom UIView when requested:
- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(id<GMSMarker>)marker
{
UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
customView.backgroundColor = [UIColor redColor];
return customView;
}
You can find a little more information by looking in the GMSMapView header, which states:
/**
* 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
