GMSCircle

@interface GMSCircle : GMSOverlay

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

• position

  Position on Earth of circle center. Ignores invalid positions.

  Declaration

  Swift

  var position: CLLocationCoordinate2D { get set }

  Objective-C

  @property (nonatomic) CLLocationCoordinate2D position;

• radius

  Radius of the circle in meters; must be positive.

  Declaration

  Swift

  var radius: CLLocationDistance { get set }

  Objective-C

  @property (nonatomic) CLLocationDistance radius;

• strokeWidth

  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;

• strokeColor

  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;

• fillColor

  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;

• +circleWithPosition:radius:

  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;
