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

Member Function Documentation
|+ (instancetype) polylineWithPath:||(nullable GMSPath *)||path|
Convenience constructor for GMSPolyline for a particular path.
Other properties will have default values.
|- (CGFloat) strokeWidth
The width of the line in screen points.
Defaults to 1.
|- (UIColor*) strokeColor
The UIColor used to render the polyline.
Defaults to [UIColor blueColor].
|- (BOOL) geodesic
Whether this line should be rendered with geodesic correction.
|- (NSArray<GMSStyleSpan *>*) spans
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.
|- (NSString*) title
Title, a short description of the overlay.
Some overlays, such as markers, will display the title on the map. The title is also the default accessibility text.
|- (GMSMapView*) map
The map this overlay is on.
Setting this property will add the overlay to the map. Setting it to nil removes this overlay from the map. An overlay may be active on at most one map at any given time.
|- (BOOL) tappable
If this overlay should cause tap notifications.
Some overlays, such as markers, will default to being tappable.
|- (int) zIndex
zIndex value overlays will be drawn on top of lower
zIndex value tile layers and overlays.
Equal values result in undefined draw ordering. Markers are an exception that regardless of
zIndex, they will always be drawn above tile layers and other non-marker overlays; they are effectively considered to be in a separate z-index group compared to other overlays.
|- (id) userData
You can use this property to associate an arbitrary object with this overlay. Google Maps SDK for iOS neither reads nor writes this property.
Note that userData should not hold any strong references to any Maps objects, otherwise a retain cycle may be created (preventing objects from being released).
