    - (nonnull instancetype)initWithLayerId:(nonnull NSString *)layerId

    Swift

    init(layerId: String, featureId: String?)

  • Associates the view annotation with a style layer ID that corresponds to its source feature’s geometry. This enables dynamic placement of view annotations within the feature geometry associated with the specified layer.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nonnull) NSString *layerId;

    Swift

    var layerId: String { get }

  • Links the view annotation to a particular feature using its feature ID within the layer. The view annotation remains hidden if the feature is offscreen. A null value indicates that any feature within the source can be utilized to position the annotation. In the case of a symbol layer, if the associated feature’s symbol is hidden, the annotation will also remain invisible. Only valid feature IDs are permissible; otherwise, an error will be raised.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSString *featureId;

    Swift

    var featureId: String? { get }
