MMKSearchLayer

@interface MMKSearchLayer : NSObject

Search manager

addSearchResultListenerWithSearchResultListener:

- (void)addSearchResultListenerWithSearchResultListener:
    (nonnull id<MMKSearchLayerResponseHandler>)searchResultListener;

Add the search result listener, which will receive notifications from the search layer.

The class does not retain the object in the 'searchResultListener' parameter. It is your responsibility to maintain a strong reference to the target object while it is attached to a class.

Parameters

searchResultListener

Search result listener to add.

removeSearchResultListenerWithSearchResultListener:

- (void)removeSearchResultListenerWithSearchResultListener:
    (nonnull id<MMKSearchLayerResponseHandler>)searchResultListener;

Remove search result listener.

Parameters

searchResultListener

Search result listener to remove.

addPlacemarkListenerWithPlacemarkListener:

- (void)addPlacemarkListenerWithPlacemarkListener:
    (nonnull id<MMKSearchLayerTapHandler>)placemarkListener;

Add a placemark listener, which will receive notifications from the search layer.

The class does not retain the object in the 'placemarkListener' parameter. It is your responsibility to maintain a strong reference to the target object while it is attached to a class.

Parameters

placemarkListener

Placemark listener to add.

removePlacemarkListenerWithPlacemarkListener:

- (void)removePlacemarkListenerWithPlacemarkListener:
    (nonnull id<MMKSearchLayerTapHandler>)placemarkListener;

Remove placemark listener

Parameters

placemarkListener

Placemark listener to remove.

setSortByDistanceWithOrigin:

- (void)setSortByDistanceWithOrigin:(nonnull MMKGeometry *)origin;

Set sort order of the results by distance from given geometry.


setPolylinePositionWithPosition:

- (void)setPolylinePositionWithPosition:(nonnull MMKPolylinePosition *)position;

When sorting by distance from polyline sets position on this polyline. Has the same effect as sorting by distance from the sub-polyline from position to the end of the polyline. Throws if no polyline is set or position is out of range.

Parameters

position

new polyline position value

resetSort

- (void)resetSort;

Reset the sort if it was previously set.


setFilterCollectionWithFilters:

- (void)setFilterCollectionWithFilters:
    (nullable MMKSearchFilterCollection *)filters;

Set search filters.

Parameters

filters

Business filters

setFiltersWithFilters:

- (void)setFiltersWithFilters:

search.FilterCollection)} instead.

Alert

Use {@link SearchLayer#setFilterCollection(const optional


setAssetsProviderWithProvider:

- (void)setAssetsProviderWithProvider:(nonnull id<MMKAssetsProvider>)provider;

Set a custom assets provider, which provides images, sizes and icon styles for placemarks.

The class does not retain the object in the 'provider' parameter. It is your responsibility to maintain a strong reference to the target object while it is attached to a class.

Parameters

provider

Assets provider (must not be null)

resetAssetsProvider

- (void)resetAssetsProvider;

Reset the assets provider to default.


selectPlacemarkWithGeoObjectId:

- (void)selectPlacemarkWithGeoObjectId:(nonnull NSString *)geoObjectId;

Select the placemark by ID.

Parameters

geoObjectId

Placemark identifier

selectedPlacemarkId

- (nullable NSString *)selectedPlacemarkId;

Selected placemark ID.

Returns

Placemark identifier if any placemark is selected, otherwise
none.

deselectPlacemark

- (void)deselectPlacemark;

Deselect all placemarks.


forceUpdateIconWithGeoObjectId:iconType:image:style:

- (void)forceUpdateIconWithGeoObjectId:(nonnull NSString *)geoObjectId
                              iconType:(MMKPlacemarkIconType)iconType
                                 image:(nonnull UIImage *)image
                                 style:(nonnull MMKIconStyle *)style;

Update the icon image for each suitable placemark. If the placemark is not found, the image will be put in a queue and will be applied once when the placemark is created. This is not the normal way to set the image. It is highly advisable to return the right image from AssetsProvider.

Parameters

geoObjectId

Placemark identifier

iconType

Icon type

image

Icon image

style

Icon style

forceUpdateMapObjects

- (void)forceUpdateMapObjects;

Force reloading all visible pins from AssetProvider. Use when there is a reason to update ALL the icons simultaneously (for example icon theme change, day/night mode, and other). This can be a pretty expensive operation, as it wipes all the map objects off of the layer and creates them from scratch. Use only if absolutely necessary.


obtainAdIconsWithEnable:

- (void)obtainAdIconsWithEnable:(BOOL)enable;

If enabled, the search layer will obtain and set advertising icons without asking AssetsProvider.

Parameters

enable

Enable mode if true, disable otherwise

setInsetsWithTop:left:bottom:right:

- (void)setInsetsWithTop:(NSUInteger)top
                    left:(NSUInteger)left
                  bottom:(NSUInteger)bottom
                   right:(NSUInteger)right;

Apply insets (in pixels) to the screen. If inset is not zero, search in the cut-off area will not be performed.

Parameters

top

Top inset.

left

Left inset.

bottom

Bottom inset.

right

Right inset.

Properties

visible

@property (nonatomic, assign, unsafe_unretained, readwrite, getter=isVisible)
    BOOL visible;

Search layer visibility. Visible by default. While the layer is invisible resubmits are not performed on map moves, but all the state changing methods (submitQuery, resubmit, deselectPlacemark, and other) are executed as usual.


valid

@property (nonatomic, readonly, getter=isValid) BOOL valid;

Tells if this object is valid or no. Any method called on an invalid object will throw an exception. The object becomes invalid only on UI thread, and only when its implementation depends on objects already destroyed by now. Please refer to general docs about the interface for details on its invalidation.
