3. and drag map when click and drag outside marker.

self.camera = [GMSCameraPosition cameraWithLatitude:-33.86 longitude:151.20 zoom:6 bearing:0 viewingAngle:0];
self.Map = [GMSMapView mapWithFrame:self.MapView.bounds camera:self.camera];
self.Map.myLocationEnabled = YES;
self.Map.delegate = self;

GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = self.camera.target;
marker.draggable = YES;

marker.snippet = @"Australia";
marker.map = self.Map;
marker.icon = [GMSMarker markerImageWithColor:[UIColor blueColor]];

Answer 1

You have to press-and-hold on the marker before it will begin dragging. I thought it wasn't working either until someone pointed this out... really needs to be in Google's documentation.
