What does the mkmapview class do in Photoshop?

The MKMapView class supports the ability to annotate the map with custom information. Because a map may have large numbers of annotations, map views differentiate between the annotation objects used to manage the annotation data and the view objects for presenting that data on the map.

How are overlay objects drawn in iOS 7?

When specifying overlays, you can add them to specific levels of the map, which allows them to be rendered above or below other types of map content. Prior to iOS 7, overlays are drawn on onscreen using overlay views, which are instances of the MKOverlayView class. When configuring your map interface, you can add overlay objects at any time.

What are the data types for the map view?

To specify locations and distances, you use the MKMapPoint, MKMapSize, and MKMapRect data types. Although you should not subclass the MKMapView class itself, you can get information about the map view’s behavior by providing a delegate object.

What can I do with the map Kit framework?

(The Map Kit framework offers the MKMarkerAnnotationView and MKPinAnnotationView classes for similar annotations in your own applications.) You could also create annotation views that cover larger portions of the map.

How are annotation objects displayed on the screen?

Each annotation object contains information about the annotation’s location on the map along with descriptive information that can be displayed in a callout. The presentation of annotation objects on the screen is handled by an annotation view, which is an instance of the MKAnnotationView class.

Are there any gestures for the map view?

In particular, map views support flick and pinch gestures for scrolling around the map and zooming in and out. Support for these gestures is enabled by default but can also be disabled using the isScrollEnabled and isZoomEnabled properties.
