Method Summary

Modifier and Type	Method and Description
MKMapRect	boundingMapRect() boundingMapRect should be the smallest rectangle that completely contains the overlay.
default boolean	canReplaceMapContent() If this method is implemented and returns YES, MKMapView may use it as a hint to skip loading or drawing the built in map content in the area covered by this overlay.
CLLocationCoordinate2D	coordinate() From MKAnnotation, for areas this should return the centroid of the area.
default boolean	intersectsMapRect(MKMapRect mapRect) Implement intersectsMapRect to provide more precise control over when the view for the overlay should be shown.

Method Detail

boundingMapRect

MKMapRect boundingMapRect()

boundingMapRect should be the smallest rectangle that completely contains the overlay. For overlays that span the 180th meridian, boundingMapRect should have either a negative MinX or a MaxX that is greater than MKMapSizeWorld.width.

canReplaceMapContent

default boolean canReplaceMapContent()

If this method is implemented and returns YES, MKMapView may use it as a hint to skip loading or drawing the built in map content in the area covered by this overlay.

coordinate

CLLocationCoordinate2D coordinate()

From MKAnnotation, for areas this should return the centroid of the area.

Specified by:

coordinate in interface MKAnnotation

intersectsMapRect

default boolean intersectsMapRect(MKMapRect mapRect)

Implement intersectsMapRect to provide more precise control over when the view for the overlay should be shown. If omitted, MKMapRectIntersectsRect([overlay boundingRect], mapRect) will be used instead.
