CMPedometerEventHandler

Declaration

typealias CMPedometerEventHandler = (CMPedometerEvent?, (any Error)?) -> Void

Discussion

You provide a block of this type when requesting pedometer events from a CMPedometer object. When a new event 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.

pedometerEvent

A CMPedometerEvent object containing the event information. 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 event was retrieved successfully.
