MGLFillStyleLayer

 
@interface MGLFillStyleLayer : MGLVectorStyleLayer

An MGLFillStyleLayer is a style layer that renders one or more filled (and optionally stroked) polygons on the map.

Use a fill style layer to configure the visual appearance of polygon or multipolygon features in vector tiles loaded by an MGLVectorSource object or MGLPolygon, MGLPolygonFeature, MGLMultiPolygon, or MGLMultiPolygonFeature instances in an MGLShapeSource object.

You can access an existing fill style layer using the -[MGLStyle layerWithIdentifier:] method if you know its identifier; otherwise, find it using the MGLStyle.layers property. You can also create a new fill style layer and add it to the style using a method such as -[MGLStyle addLayer:].

Example

let layer = MGLFillStyleLayer(identifier: parks, source: parks)
layer.sourceLayerIdentifier = parks
layer.fillColor = MGLStyleValue(rawValue: .green)
layer.predicate = NSPredicate(format: type == %@, national-park)
mapView.style?.addLayer(layer)

Accessing the Paint Attributes

  • Whether or not the fill should be antialiased.

    The default value of this property is an MGLStyleValue object containing an NSNumber object containing YES. Set this property to nil to reset it to the default value.

    This attribute corresponds to the fill-antialias layout property in the Mapbox Style Specification.

    Declaration

    Objective-C

    @property (getter=isFillAntialiased, assign, readwrite, nonatomic,
          null_resettable) MGLStyleValue<NSNumber *> *fillAntialiased;

    Swift

    var fillAntialiased: MGLStyleValue

  • The color of the filled part of this layer.

    The default value of this property is an MGLStyleValue object containing NSColor.blackColor. Set this property to nil to reset it to the default value.

    This property is only applied to the style if fillPattern is set to nil. Otherwise, it is ignored.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSColor *> *fillColor;

    Swift

    var fillColor: MGLStyleValue

  • The opacity of the entire fill layer. In contrast to the fillColor, this value will also affect the 1pt stroke around the fill, if the stroke is used.

    The default value of this property is an MGLStyleValue object containing an NSNumber object containing the float 1. Set this property to nil to reset it to the default value.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSNumber *> *fillOpacity;

    Swift

    var fillOpacity: MGLStyleValue

  • The outline color of the fill. Matches the value of fillColor if unspecified.

    This property is only applied to the style if fillPattern is set to nil, and fillAntialiased is set to an MGLStyleValue object containing an NSNumber object containing YES. Otherwise, it is ignored.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSColor *> *fillOutlineColor;

    Swift

    var fillOutlineColor: MGLStyleValue

  • Name of image in sprite to use for drawing image fills. For seamless patterns, image width and height must be a factor of two (2, 4, 8, …, 512).

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSString *> *fillPattern;

    Swift

    var fillPattern: MGLStyleValue

  • The geometry’s offset.

    This property is measured in points.

    The default value of this property is an MGLStyleValue object containing an NSValue object containing a CGVector struct set to 0 points rightward and 0 points upward. Set this property to nil to reset it to the default value.

    This attribute corresponds to the fill-translate layout property in the Mapbox Style Specification.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSValue *> *fillTranslation;

    Swift

    var fillTranslation: MGLStyleValue

  • Controls the translation reference point.

    The default value of this property is an MGLStyleValue object containing an NSValue object containing MGLFillTranslationAnchorMap. Set this property to nil to reset it to the default value.

    This property is only applied to the style if fillTranslation is non-nil. Otherwise, it is ignored.

    This attribute corresponds to the fill-translate-anchor layout property in the Mapbox Style Specification.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSValue *> *fillTranslationAnchor;

    Swift

    var fillTranslationAnchor: MGLStyleValue
