RMCircleAnnotation Class Reference
| Inherits from | RMShapeAnnotation : RMAnnotation : NSObject |
| Declared in | RMCircleAnnotation.h |
Overview
An RMCircleAnnotation is a concrete subclass of RMShapeAnnotation that is used to represent a circle shape on the map. The annotation will automatically have a layer created when needed that displays an RMCircle.
If you wish to customize the layer appearance in more detail, you should instead create an RMAnnotation and configure its layer directly. Providing a layer manually for instances of RMCircleAnnotation will not have any effect.

Properties
centerCoordinate
The circle annotation’s center coordinate.
@property (nonatomic, assign) CLLocationCoordinate2D centerCoordinateDiscussion
The circle annotation’s center coordinate.
Declared In
RMCircleAnnotation.hlineWidthInPixels
The circle annotation’s line width.
@property (nonatomic, assign) CGFloat lineWidthInPixelsDiscussion
The circle annotation’s line width.
Declared In
RMCircleAnnotation.hradiusInMeters
The radius of the circle annotation in projected meters. Regardless of map zoom, the circle will change visible size to continously represent this radius on the map.
@property (nonatomic, assign) CGFloat radiusInMetersDiscussion
The radius of the circle annotation in projected meters. Regardless of map zoom, the circle will change visible size to continously represent this radius on the map.

- aMapView
The map view on which to place the annotation.
- centerCoordinate
The center of the annotation.
- radiusInMeters
