GMSCircle

@interface GMSCircle : GMSOverlay

A circle on the Earth’s surface (spherical cap).

  • Position on Earth of circle center. Ignores invalid positions.

    Declaration

    Swift

    var position: CLLocationCoordinate2D { get set }

    Objective-C

    @property (nonatomic) CLLocationCoordinate2D position;

  • Radius of the circle in meters; must be positive.

    Declaration

    Swift

    var radius: CLLocationDistance { get set }

    Objective-C

    @property (nonatomic) CLLocationDistance radius;

  • The width of the circle’s outline in screen points. Defaults to 1. As per GMSPolygon, the width does not scale when the map is zoomed.

    Setting strokeWidth to 0 results in no stroke.

    Declaration

    Swift

    var strokeWidth: CGFloat { get set }

    Objective-C

    @property (nonatomic) CGFloat strokeWidth;

  • The color of this circle’s outline. The default value is black.

    Declaration

    Swift

    var strokeColor: UIColor? { get set }

    Objective-C

    @property (nonatomic, nullable) UIColor *strokeColor;

  • The interior of the circle is painted with fillColor. The default value is nil, resulting in no fill.

    Declaration

    Swift

    var fillColor: UIColor? { get set }

    Objective-C

    @property (nonatomic, nullable) UIColor *fillColor;

  • Convenience constructor for GMSCircle for a particular position and radius. Other properties will have default values. An invalid position will result in an overlay object that cannot be drawn on the map.

    Declaration

    Swift

    convenience init(position: CLLocationCoordinate2D, radius: CLLocationDistance)

    Objective-C

    + (nonnull instancetype)circleWithPosition:(CLLocationCoordinate2D)position
                                    radius:(CLLocationDistance)radius;
