New basemap styling is coming soon to Google Maps Platform. This update to map styling includes a new default color palette, modernized pins, and improvements to map experiences and usability. All map styles will be automatically updated in March 2025. For more information on availability and how to opt in earlier, see
New map style for Google Maps Platform.
GoogleMaps Framework Reference
GMSPolyline
GMSPolyline
specifies the available options for a polyline that exists on the Earth’s surface.
It is drawn as a physical line between the points specified in path
.
-
The path that describes this polyline.
Declaration
Swift
@NSCopying var path: GMSPath? { get set }
Objective-C
@property (nonatomic, copy, nullable) GMSPath *path;
-
The width of the line in screen points. Defaults to 1.
Declaration
Swift
var strokeWidth: CGFloat { get set }
Objective-C
@property (nonatomic) CGFloat strokeWidth;
-
The UIColor
used to render the polyline. Defaults to [UIColor blueColor]
.
Declaration
Swift
var strokeColor: UIColor { get set }
Objective-C
@property (nonatomic) UIColor *_Nonnull strokeColor;
-
Whether this line should be rendered with geodesic correction.
Declaration
Swift
var geodesic: Bool { get set }
Objective-C
@property (nonatomic) BOOL geodesic;
-
Convenience constructor for GMSPolyline
for a particular path. Other properties will have
default values.
Declaration
Swift
convenience init(path: GMSPath?)
Objective-C
+ (nonnull instancetype)polylineWithPath:(nullable GMSPath *)path;
-
An array containing GMSStyleSpan
, the spans used to render this polyline.
If this array contains fewer segments than the polyline itself, the final segment will be applied
over the remaining length. If this array is unset or empty, then strokeColor
is used for the
entire line instead.
Declaration
Objective-C
@property (nonatomic, copy, nullable) NSArray<GMSStyleSpan *> *spans;
