# MKShape

An abstract class that defines the basic properties for all shape-based overlay objects.

```
class MKShape
```

## Overview

You can’t instantiate this class directly; use a subclass instead. Subclasses are responsible for defining the geometry of the shape and providing an appropriate value for the coordinate property they inherit from the [`MKAnnotation`](/documentation/MapKit/MKAnnotation) protocol.

## Topics

### Accessing the shape attributes

[`title`](/documentation/MapKit/MKShape/title)

The title of the shape annotation.

[`subtitle`](/documentation/MapKit/MKShape/subtitle)

The subtitle of the shape annotation.
