  • Unavailable

    Undocumented

    Declaration

    Objective-C

    - (nonnull instancetype)init NS_UNAVAILABLE;

  • Unavailable

    Undocumented

    Declaration

    Objective-C

    + (nonnull instancetype)new NS_UNAVAILABLE;

  • Creates the infrastructure needed for rendering the map. It should be called before any call to render method. Must be called on the render thread.

    Declaration

    Objective-C

    - (void)createRenderer;

    Swift

    func createRenderer()

  • Destroys the infrastructure needed for rendering the map, releasing resources. Must be called on the render thread.

    Swift

    func render()

  • Sets the size of the map.

    Declaration

    Objective-C

    - (void)setSizeForSize:(nonnull MBMSize *)size;

    Swift

    func setSizeFor(_ size: MBMSize)

    Swift

    func isGestureInProgress() -> Bool

    Return Value

    true if a gesture is currently in progress, false otherwise.

    Declaration

    Objective-C

    - (void)setUserAnimationInProgressForInProgress:(BOOL)inProgress;

    Swift

  • Updates the state object of a feature within a style source.

    Update entries in the state object of a given feature within a style source. Only properties of the state object will be updated. A property in the feature state object that is not listed in state will retain its previous value.

    Note that updates to feature state are asynchronous, so changes made by this method migth not be immediately visible using getStateFeature.

    Declaration

    Objective-C

    - (void)setFeatureStateForSourceId:(nonnull NSString *)sourceId

                             state:(nonnull id)state;

    Swift

    func setFeatureStateForSourceId(_ sourceId: String, sourceLayerId: String?, featureId: String, state: Any)

    The style source identifier.
    sourceLayerId

    The style source layer identifier (for multi-layer sources such as vector sources).
    featureId

    The feature identifier of the feature whose state should be updated.
    state

    The state object with properties to update with their respective new values.

  • Removes entries from a feature state object.

    Remove a specified property or all property from a feature’s state object, depending on the value of stateKey.

    Note that updates to feature state are asynchronous, so changes made by this method migth not be immediately visible using getStateFeature.

  • Enables or disables the experimental render cache feature.

    Render cache is an experimental feature aiming to reduce resource usage of map rendering by caching intermediate rendering results of tiles into specific cache textures for reuse between frames. Performance benefit of the cache depends on the style as not all layers are cacheable due to e.g. viewport aligned features. Render cache always prefers quality over performance.

    options

    The render cache options defining the render cache behavior.

  • Returns the render cache options used by the map.

    Declaration

    Objective-C

    - (nonnull MBMRenderCacheOptions *)getRenderCacheOptions;

    Swift

    func getRenderCacheOptions() -> MBMRenderCacheOptions
