Page Summary
-
GMSMapLayeris a custom subclass ofCALayerused as the layer class forGMSMapViewand should not be directly instantiated. -
It provides access to the camera properties of the
GMSMapView, like latitude, longitude, bearing, zoom level, and viewing angle. -
Modifying or animating
GMSMapLayerproperties can interrupt user gestures on the map and vice-versa. -
Developers can use these properties to programmatically control the map's camera view.

GMSCALayer
GMSMapLayer
is a custom subclass of CALayer
, provided as the layer class on GMSMapView
.
This layer should not be instantiated directly. It provides model access to the camera normally
defined on GMSMapView
.
Modifying or animating these properties will typically interrupt any current gesture on GMSMapView
, e.g., a user’s pan or rotation. Similarly, if a user performs an enabled gesture
during an animation, the animation will stop ‘in-place’ (at the current presentation value).
