intersects(_:)
Returns a Boolean value that indicates whether the specified rectangle intersects the overlay’s shape.
Declaration
optional func intersects(_ mapRect: MKMapRect) -> BoolParameters
- mapRect:
The rectangle to intersect with the overlay’s area.
Return Value
true if any part of the map rectangle intersects the receiver’s shape, or false if it doesn’t.
Discussion
You can implement this method to provide more specific bounds-checking for an overlay. If you don’t implement it, the method uses the bounding rectangle to detect intersections.
