GoogleNavigation Framework Reference

  • GMSStrokeStyle defines the visual appearance of lines or strokes on a map, such as those used for polylines.

  • It supports solid colors, gradients, and repeating image patterns (stamps) to style strokes.

  • You can create styles with solid colors using solidColor:, gradients using gradientFromColor:toColor:, and transparent strokes with stamps using transparentStrokeWithStampStyle:.

  • The stampStyle property allows applying a repeating image pattern over the stroke, with transparency allowing the underlying stroke color to show through.

GMSStrokeStyle

@interface GMSStrokeStyle : NSObject

Describes the drawing style for one-dimensional entities such as polylines.

  • A repeated image over the stroke to allow a user to set a 2D texture on top of a stroke. If the image has transparent or semi-transparent portions, the underlying stroke color will show through in those places. Solid portions of the stamp will completely cover the base stroke.

    Declaration

    Swift

    var stampStyle: GMSStampStyle? { get set }

    Objective-C

    @property (nonatomic, strong, nullable) GMSStampStyle *stampStyle;

  • Creates a solid color stroke style.

    Declaration

    Swift

    class func solidColor(_ color: UIColor) -> Self

    Objective-C

    + (nonnull instancetype)solidColor:(nonnull UIColor *)color;

  • Creates a gradient stroke style interpolating from fromColor to toColor.

    Declaration

    Swift

    class func gradient(from fromColor: UIColor, to toColor: UIColor) -> Self

    Objective-C

    + (nonnull instancetype)gradientFromColor:(nonnull UIColor *)fromColor
                                  toColor:(nonnull UIColor *)toColor;

  • Creates a transparent stroke style and sets the stampStyle.

    Declaration

    Swift

    class func transparentStroke(withStamp stampStyle: GMSStampStyle) -> Self

    Objective-C

    + (nonnull instancetype)transparentStrokeWithStampStyle:
    (nonnull GMSStampStyle *)stampStyle;
