AI-generated Key Takeaways

• GMSMarkerLayer is a subclass of GMSOverlayLayer used for animating properties of a GMSMarker.

• It allows animation of latitude, longitude, rotation, and opacity of the associated marker.

• This layer is not directly rendered and relies on the OpenGL layer of GMSMapView.

• Adjustments or animations to default properties of CALayer will not affect GMSMarkerLayer.

GMSMarkerLayer

@interface GMSMarkerLayer : GMSOverlayLayer

GMSMarkerLayer is a subclass of GMSOverlayLayer, available on a per-marker basis, that allows animation of several properties of its associated GMSMarker.

Note that this CALayer is never actually rendered directly, as GMSMapView is provided entirely via an OpenGL layer. As such, adjustments or animations to ‘default’ properties of CALayer will not have any effect.

• latitude

  Latitude, part of position on GMSMarker.

  Declaration

  Swift

  var latitude: CLLocationDegrees { get set }

  Objective-C

  @property (nonatomic) CLLocationDegrees latitude;

• longitude

  Longitude, part of position on GMSMarker.

  Declaration

  Swift

  var longitude: CLLocationDegrees { get set }

  Objective-C

  @property (nonatomic) CLLocationDegrees longitude;

• rotation

  Rotation, as per GMSMarker.

  Declaration

  Swift

  var rotation: CLLocationDegrees { get set }

  Objective-C

  @property (nonatomic) CLLocationDegrees rotation;

• opacity

  Opacity, as per GMSMarker.

  Declaration

  Swift

  var opacity: Float { get set }

  Objective-C
