GMSPolygon defines a polygon that appears on the map.
A polygon (like a polyline) defines a series of connected coordinates in an ordered sequence; additionally, polygons form a closed loop and define a filled region.

Member Function Documentation
Convenience constructor for GMSPolygon for a particular path.
Other properties will have default values.
The path that describes this polygon.
The coordinates composing the path must be valid.
The array of GMSPath instances that describes any holes in this polygon.
The coordinates composing each path must be valid.
|- (CGFloat) strokeWidth
The width of the polygon outline in screen points.
Defaults to 1.
|- (UIColor*) strokeColor
The color of the polygon outline.
Defaults to nil.
|- (UIColor*) fillColor
The fill color.
Defaults to blueColor.
|- (BOOL) geodesic
Whether this polygon should be rendered with geodesic correction.
|- (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.
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).
