MKDirections.ETAHandler
The block to use for processing travel-time information.
Declaration
typealias ETAHandler = (MKDirections.ETAResponse?, (any Error)?) -> VoidParameters
- response:
The
responseparameter contains the travel-time response. If an error occurs or the framework can’t determine the travel time, this parameter isnil. - error:
The
errorparameter contains information about any errors that occur. If no errors occur, this parameter isnil.
Discussion
The implementation of your block needs to check for a value in the error parameter and, if that parameter is nil, incorporate the travel-time information from the response parameter.
