# MKMultiPoint

An abstract class that defines the common behavior that open and closed polygon overlays share.

```
class MKMultiPoint
```

## Overview

Don’t create instances of this class directly. Instead, create instances of the [`MKPolygon`](/documentation/MapKit/MKPolygon) or [`MKPolyline`](/documentation/MapKit/MKPolyline) classes. However, you can use the methods and property of this class to access information about the specific points associated with the line or polygon.

## Topics

### Accessing the points in the shape

[`-  points`](/documentation/MapKit/MKMultiPoint/points())

Returns an array of map points associated with the shape.

[`pointCount`](/documentation/MapKit/MKMultiPoint/pointCount)

The number of points associated with the shape.

[`-  locationAtPointIndex:`](/documentation/MapKit/MKMultiPoint/location(atPointIndex:))

Translates a point index into a unit distance along the shape.

[`locations(at:)`](/documentation/MapKit/MKMultiPoint/locations(at:))

Translates a point index set into a unit distance along the shape.

[`-  locationsAtPointIndexes:`](/documentation/MapKit/MKMultiPoint/locationsAtPointIndexes:)

Returns a set of unit distance values that correspond to the point indexes along the shape.

### Getting coordinate values

[`-  getCoordinates:range:`](/documentation/MapKit/MKMultiPoint/getCoordinates(_:range:))

Retrieves one or more points associated with the shape and converts them to coordinate values.
