AI-generated Key Takeaways

• GMSMapLayer is a custom subclass of CALayer used as the layer class for GMSMapView and should not be directly instantiated.

• It provides access to the camera properties like latitude, longitude, bearing, zoom level, and viewing angle, usually controlled through GMSMapView.

• Modifying or animating these properties might interrupt ongoing user gestures on the map, and user gestures during animations will halt the animation.

GMSMapLayer

@interface GMSMapLayer : 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).
