AWFMapStrategyDelegate

Objective-C

@protocol AWFMapStrategyDelegate <NSObject>

Swift

protocol AWFMapStrategyDelegate : NSObjectProtocol

The AWFMapStrategyDelegate protocol defines a set of optional methods that you can use to receive messages related to the internal map view being managed by a map strategy.

  • Tells the delegate that the map view is about to change its visible region.

    Declaration

    Objective-C

    - (void)mapStrategy:(nonnull id<AWFMapStrategy>)strategy
    regionWillChangeFromBounds:(nonnull AWFMapCoordinateBounds *)bounds;

    Swift

    optional func mapStrategy(_ strategy: AWFMapStrategy, regionWillChangeFrom bounds: AWFMapCoordinateBounds)

    Parameters

    strategy

    The map strategy managing the map view.
    bounds

    The visible bounds of the map view before the region change.

  • Tells the delegate that the map view has changed its visible region.

    Declaration

    Objective-C

    - (void)mapStrategy:(nonnull id<AWFMapStrategy>)strategy
    regionDidChangeToBounds:(nonnull AWFMapCoordinateBounds *)bounds;

    Swift

    optional func mapStrategy(_ strategy: AWFMapStrategy, regionDidChangeTo bounds: AWFMapCoordinateBounds)

    Parameters

    strategy

    The map strategy managing the map view.
    bounds

    The visible bounds of the map view after the region change.

  • Tells the delegate that a polygon overlay was tapped on the map.

    Declaration

    Objective-C

    - (void)mapStrategy:(nonnull id<AWFMapStrategy>)strategy
      didTapPolygon:(nonnull id)polygon
       atCoordinate:(CLLocationCoordinate2D)coordinate;

    Swift

    optional func mapStrategy(_ strategy: AWFMapStrategy, didTapPolygon polygon: Any, at coordinate: CLLocationCoordinate2D)

    Parameters

    strategy

    The map strategy managing the map view.
    polygon

    The polygon overlay that was tapped.
    coordinate

    The map coordinate at which the tap was detected.

  • Tells the delegate that an overlay was added to the map view.

    Declaration

    Objective-C

    - (void)mapStrategy:(nonnull id<AWFMapStrategy>)strategy
      didAddOverlay:(nonnull id)overlay;

    Swift

    optional func mapStrategy(_ strategy: AWFMapStrategy, didAddOverlay overlay: Any)

    Parameters

    strategy

    The map strategy that added the overlay.
    overlay

    The overlay that was added.

  • Tells the delegate that the map’s callout is about to be displayed for a selected annotation, allowing the delegate to prepare the map for any map region changes that may occur to accomodate the callout’s view.

    Declaration

    Objective-C

    - (void)mapStrategyWillDisplayCallout:(nonnull id<AWFMapStrategy>)strategy;

    Swift

    optional func mapStrategyWillDisplayCallout(_ strategy: AWFMapStrategy)

    Parameters

    strategy

    The map strategy that is managing the callout.
