VBDMapCamera

@interface VBDMapCamera : NSObject <NSSecureCoding, NSCopying>

An VBDMapCamera object represents a viewpoint from which the user observes some point on an VBDMapView.

  • Coordinate at the center of the map view.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic) CLLocationCoordinate2D centerCoordinate;

  • Heading measured in degrees clockwise from true north.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic) CLLocationDirection heading;

  • Pitch toward the horizon measured in degrees, with 0 degrees resulting in a two-dimensional map.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic) CGFloat pitch;

  • Meters above ground level.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic) CLLocationDistance altitude;

  • Returns a new camera with all properties set to 0.

    Declaration

    Objective-C

    + (nonnull instancetype)camera;

  • Returns a new camera using based on information about the camera’s viewpoint and focus point.

    Declaration

    Objective-C

    + (nonnull instancetype)
cameraLookingAtCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
              fromEyeCoordinate:(CLLocationCoordinate2D)eyeCoordinate
                    eyeAltitude:(CLLocationDistance)eyeAltitude;

    Parameters

    centerCoordinate

    The geographic coordinate on which the map should be centered.
    eyeCoordinate

    The geometric coordinate at which the camera should be situated.
    eyeAltitude

    The altitude (measured in meters) above the map at which the camera should be situated. The altitude may be less than the distance from the camera’s viewpoint to the camera’s focus point.

  • Returns a new camera with the given distance, pitch, and heading.

    Declaration

    Objective-C

    + (nonnull instancetype)
cameraLookingAtCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
                   fromDistance:(CLLocationDistance)distance
                          pitch:(CGFloat)pitch
                        heading:(CLLocationDirection)heading;

    Parameters

    centerCoordinate

    The geographic coordinate on which the map should be centered.
    distance

    The straight-line distance from the viewpoint to the centerCoordinate.
    pitch

    The viewing angle of the camera, measured in degrees. A value of 0 results in a camera pointed straight down at the map. Angles greater than 0 result in a camera angled toward the horizon.
    heading

    The camera’s heading, measured in degrees clockwise from true north. A value of 0 means that the top edge of the map view corresponds to true north. The value 90 means the top of the map is pointing due east. The value 180 means the top of the map points due south, and so on.
