Prefetching

  • When loading a map, if prefetchZoomDelta is set to any number greater than 0, the map will first request a tile for zoom - prefetchZoomDelta in an attempt to display a full map at lower resolution as quick as possible.

    It will get clamped at the tile source minimum zoom. The default delta is 4.

    Declaration

    Swift

    public var prefetchZoomDelta: UInt8 { get set }

  • Gets the resource options for the map.

    All optional fields of the returned object are initialized with the actual values.

    Declaration

    Swift

    public var resourceOptions: ResourceOptions { get }

  • Clears temporary map data.

    Clears temporary map data from the data path defined in the given resource options. Useful to reduce the disk usage or in case the disk cache contains invalid data.

Camera options setters/getters

  • Changes the map view by any combination of center, zoom, bearing, and pitch, without an animated transition. The map will retain its current values for any details not passed via the camera options argument. It is not guaranteed that the provided CameraOptions will be set, the map may apply constraints resulting in a different CameraState.

    Important

    This method does not cancel existing animations. Call CameraAnimationsManager.cancelAnimations()to cancel existing animations.

    Declaration

    Swift

    public func setCamera(to cameraOptions: CameraOptions)

    Parameters

    cameraOptions

    New camera options

  • Returns the current camera state

    Declaration

    Swift

    public var cameraState: CameraState { get }

  • Sets/get the map view with the free camera options.

    FreeCameraOptions provides more direct access to the underlying camera entity. For backwards compatibility the state set using this API must be representable with CameraOptions as well. Parameters are clamped to a valid range or discarded as invalid if the conversion to the pitch and bearing presentation is ambiguous. For example orientation can be invalid if it leads to the camera being upside down or the quaternion has zero length.

    Declaration

    Swift

    public var freeCameraOptions: FreeCameraOptions { get set }

    Parameters

    freeCameraOptions

    The free camera options to set.

  • Returns the bounds of the map.

    public var cameraBounds: CameraBounds { get }

  • Sets the bounds of the map.

    Throws

    MapError

    Declaration

    Swift

    public func setCameraBounds(with options: CameraBoundsOptions) throws

    Parameters

    options

    New camera bounds. Nil values will not take effect.

    level).
  2. `leaves`: returns all the leaves of a cluster (given its cluster_id)
  3. `expansion-zoom`: returns the zoom on which the cluster expands
