Designated initializer.
Configures this GMSCameraPosition with all available camera properties. Building a GMSCameraPosition via this initializer (or by the following convenience constructors) will implicitly clamp camera values.
- Parameters:
-
target Location on the earth towards which the camera points. zoom The zoom level near the center of the screen. bearing Bearing of the camera in degrees clockwise from true north. viewingAngle The angle, in degrees, of the camera angle from the nadir (directly facing the Earth)
| - (instancetype) initWithTarget: | (CLLocationCoordinate2D) | target | |
| zoom: | (float) | zoom | |
Convenience initializer for GMSCameraPosition for a particular target and zoom level.
This will set the bearing and viewingAngle properties of this camera to zero defaults (i.e., directly facing the Earth's surface, with the top of the screen pointing north).
- Parameters:
-
target Location on the earth towards which the camera points. zoom The zoom level near the center of the screen.
| - (instancetype) initWithLatitude: | (CLLocationDegrees) | latitude | |
| longitude: | (CLLocationDegrees) | longitude | |
| zoom: | (float) | zoom | |
Convenience initializer for GMSCameraPosition for a particular latitidue, longitude and zoom level.
This will set the bearing and viewingAngle properties of this camera to zero defaults (i.e., directly facing the Earth's surface, with the top of the screen pointing north).
- Parameters:
-
latitude The latitude component of the location towards which the camera points. longitude The latitude component of the location towards which the camera points. zoom The zoom level near the center of the screen.

| longitude: | (CLLocationDegrees) | longitude | |
| zoom: | (float) | zoom | |
| bearing: | (CLLocationDirection) | bearing | |
| viewingAngle: | (double) | viewingAngle | |
Convenience initializer for GMSCameraPosition, with latitude/longitude and all other camera properties as per -initWithTarget:zoom:bearing:viewingAngle:.
- Parameters:
-
latitude The latitude component of the location towards which the camera points. longitude The latitude component of the location towards which the camera points. zoom The zoom level near the center of the screen. bearing Bearing of the camera in degrees clockwise from true north. viewingAngle The angle, in degrees, of the camera angle from the nadir (directly facing the Earth)
| + (instancetype) cameraWithTarget: | (CLLocationCoordinate2D) | target | |
| zoom: | (float) | zoom | |
Convenience constructor for GMSCameraPosition for a particular target and zoom level.
This will set the bearing and viewingAngle properties of this camera to zero defaults (i.e., directly facing the Earth's surface, with the top of the screen pointing north).
| + (instancetype) cameraWithLatitude: | (CLLocationDegrees) | latitude | |
| longitude: | (CLLocationDegrees) | longitude | |
| zoom: | (float) | zoom | |
Convenience constructor for GMSCameraPosition, as per cameraWithTarget:zoom:.
| + (instancetype) cameraWithTarget: | (CLLocationCoordinate2D) | target | |
| zoom: | (float) | zoom | |
| bearing: | (CLLocationDirection) | bearing | |
| viewingAngle: | (double) | viewingAngle | |
Convenience constructor for GMSCameraPosition, with all camera properties as per initWithTarget:zoom:bearing:viewingAngle:.
| + (instancetype) cameraWithLatitude: | (CLLocationDegrees) | latitude | |
| longitude: | (CLLocationDegrees) | longitude | |
| zoom: | (float) | zoom | |
| bearing: | (CLLocationDirection) | bearing | |
| viewingAngle: | (double) | viewingAngle | |
Convenience constructor for GMSCameraPosition, with latitude/longitude and all other camera properties as per initWithTarget:zoom:bearing:viewingAngle:.
| + (float) zoomAtCoordinate: | (CLLocationCoordinate2D) | coordinate | |
| forMeters: | (CLLocationDistance) | meters | |
| perPoints: | (CGFloat) | points | |
Get the zoom level at which meters distance, at given coord on Earth, correspond to the specified number of screen points.
For extremely large or small distances the returned zoom level may be smaller or larger than the minimum or maximum zoom level allowed on the camera.
This helper method is useful for building camera positions that contain specific physical areas on Earth.
