MapCameraLimits

public class MapCameraLimits
extension MapCameraLimits: NativeBase
extension MapCameraLimits: Hashable

Controls constraints on map camera parameters.

When constraints are set, they are enforced for current camera state and for all future changes to the camera.

When setting, limits are applied on next rendering loop.

  • Absolute minimum possible value of tilt angle.

    Declaration

    Swift

    public static let minTilt: Double

  • Absolute maximum possible value of tilt angle.

    Declaration

    Swift

    public static let maxTilt: Double

  • Absolute minimum possible value of zoom level.

    Declaration

    Swift

    public static let minZoomLevel: Double

  • Absolute maximum possible value of zoom level.

    Declaration

    Swift

    public static let maxZoomLevel: Double

  • The tilt range that can be applied to the camera. The supported values fall inside code> range. Setting values outside the supported range will be ignored.

    By default, a code> tilt range is set during initialization.

    If the current camera tilt exceeds the new limit range, it will immediately be set to minimum or maximum, depending on which is closest.

    Declaration

    Swift

    public var tiltRange: AngleRange { get set }

  • The bearing range within which the camera can be rotated. If the current camera bearing exceeds the limit range, it will immediately be set to minimum or maximum, depending on which is closest.

    By default, a full circle is set during initialization.

    Declaration

    Swift

    public var bearingRange: AngleRange { get set }

  • The zoom range that can be applied to the camera. The supported values fall inside code> range. Values outside the supported zoom range are ignored.

    By default, a code> zoom range is set during initialization.

    If the current camera zoom exceeds the limit range, it will immediately be set to minimum or maximum, depending on which is closest.

    Declaration

    Swift

    public var zoomRange: MapMeasureRange { get set }

  • Geographical area to which the camera target is limited. Absence of a value means that there is no limit.

    Declaration

    Swift

    public var targetArea: GeoBox? { get set }

  • Sets the bearing range within which the camera can rotate at a given zoom.

    The resulting camera bearing at a zoom is an interpolated value of the ranges set for closest matching zoom values. When no bearing range is specified for MapCameraLimits.minZoomLevel, the bearing range set through MapCameraLimits.bearingRange is used for interpolation.

    Zoom values outside the supported zoom range are ignored. By default, the maximum bearing range for all zoom values is set during initialization.

    Declaration

    Swift

    public func setBearingRangeAtZoom(_ zoom: MapMeasure, bearingRange: AngleRange)

    Parameters

    zoom

    Zoom at which the range is set.
    bearingRange

    Bearing range.

  • Clears bearing ranges for all zoom values and resets MapCameraLimits.bearingRange to default.

    Declaration

    Swift

    public func clearBearingRanges()

  • Sets tilt ranges that can be set on the camera at given zoom.

    The resulting camera tilt at a zoom is an interpolated value of the ranges set for closest matching zoom values. When no tilt range is specified for MapCameraLimits.minZoomLevel, the tilt range set through MapCameraLimits.tiltRange is used for interpolation.

    Zoom or tilt values outside the supported zoom and tilt range are ignored. By default, the maximum tilt range for all zoom values is set during initialization.

    Declaration

    Swift

    public func setTiltRangeAtZoom(_ zoom: MapMeasure, tiltRange: AngleRange)

    Parameters

    zoom

    Zoom at which the range is set.
    tiltRange

    Tilt range.

  • Clears tilt ranges for all zoom values and resets MapCameraLimits.tiltRange to default.

    Declaration

    Swift

    public func clearTiltRanges()
