GoogleMaps Framework Reference

  • GMSFeatureStyle defines the visual appearance of map features, such as fill color, border color, and border width.

  • It can be used to style points, lines, and polygons on a Google Map.

  • Developers can create and customize styles using properties like fillColor, strokeColor, and strokeWidth.

  • For points, the pointRadius property controls the size.

  • GMSFeatureStyle is immutable, but a mutable copy (GMSMutableFeatureStyle) can be created for modifications.

GMSFeatureStyle


@interface GMSFeatureStyle : NSObject <NSCopying, NSMutableCopying>

Specifies how a map feature should appear when displayed on a map.

  • Creates a new style.

    Declaration

    Objective-C

    + (nonnull instancetype)styleWithFillColor:(nullable UIColor *)fillColor
                               strokeColor:(nullable UIColor *)strokeColor
                               strokeWidth:(CGFloat)strokeWidth;

  • Initializes a new style.

    Declaration

    Swift

    init(fill fillColor: UIColor?, stroke strokeColor: UIColor?, strokeWidth: CGFloat)

    Objective-C

    - (nonnull instancetype)initWithFillColor:(nullable UIColor *)fillColor
                              strokeColor:(nullable UIColor *)strokeColor
                              strokeWidth:(CGFloat)strokeWidth;

  • Initializes a default style.

    Declaration

    Swift

    init()

    Objective-C

    - (nonnull instancetype)init;

  • Specifies the fill color, including the alpha channel.

    Declaration

    Swift

    @NSCopying var fillColor: UIColor? { get }

    Objective-C

    @property (nonatomic, copy, readonly, nullable) UIColor *fillColor;

  • Specifies the border color, including the alpha channel.

    Declaration

    Swift

    @NSCopying var strokeColor: UIColor? { get }

    Objective-C

    @property (nonatomic, copy, readonly, nullable) UIColor *strokeColor;

  • Specifies the border width, in screen points.

    Declaration

    Swift

    var strokeWidth: CGFloat { get }

    Objective-C

    @property (nonatomic, readonly) CGFloat strokeWidth;

  • Specifies the radius of a point. Only applies to point geometries.

    Declaration

    Swift

    var pointRadius: CGFloat { get }

    Objective-C

    @property (nonatomic, readonly) CGFloat pointRadius;

  • Declaration

    Swift

    func copy() -> FeatureStyle

    Objective-C

    - (GMSFeatureStyle *)copy;

  • Declaration

    Swift

    func mutableCopy() -> MutableFeatureStyle

    Objective-C

    - (GMSMutableFeatureStyle *)mutableCopy;
