CMPedometerHandler

Declaration

typealias CMPedometerHandler = (CMPedometerData?, (any Error)?) -> Void

Discussion

You provide a block of this type when requesting data from the CMPedometer object. When the data becomes available, the pedometer object delivers that data to your block for processing. If there was an error retrieving the data, the pedometer object provides an error object instead.

This block has no return value and takes the following parameters:

pedometerData

A CMPedometerData object containing the available data. If there was an error retrieving the data, this parameter is nil.

error

An NSError object if there was a problem or nil if the pedometer data was retrieved successfully.
