MKDirections.DirectionsHandler

The block to use for processing the requested route information.

Declaration

typealias DirectionsHandler = (MKDirections.Response?, (any Error)?) -> Void

Parameters

  • response:

    The response parameter contains the route information for the request. If an error occurs or the framework can’t determine a route, this parameter is nil.

  • error:

    The error parameter contains information about any errors that occur. If no errors occur, this parameter is nil.

Discussion

The implementation of your block needs to check for a value in the error parameter and, if that parameter is nil, incorporate the route information from the response parameter.
