WatchOS2 - New API - Core Motion CMPedometer - Example

WatchOS 2 Experiments - New API Components - Pedometer with Core Motion.

Example

Requirements

• = XCode 8.0.

• = Swift 3.

Tested on WatchOS2, iOS 9.0 Simulators, iPhone 6 8.4, Watch.

Important

this is the Xcode 8 / Swift 3 updated project.

Usage

To run the example project, download or clone the repo.

Caution

CMPedometerData only work on Hardware (your apple watch!), not on simulators..

Example Code!

Configure :

• Drag and drop more WKInterfaceLabel to Interface Controller (Storyboard)
• connect your WKInterfaceLabel to your Interface Controller class
• import CoreMotion to your Interface Controller class
• put code to your controller class.

// create pedometer object
let corePedometer = CMPedometer()

• in willActivate() method

// define start date
let startDate = NSDate()

// get CMPedometerData updates from startDate
if CMPedometer.isPaceAvailable() {

	self.corePedometer.startPedometerUpdatesFromDate(startDate, withHandler: { (data:CMPedometerData?, error:NSError?) -> Void in

		if (error == nil) {

            // rounded distance value (in meter eg: 12.54)
            let distance = data!.distance!.doubleValue.m
            let np = 2.0
            let multi = pow(10.0, np)
            let rounded = round(distance * multi) / multi
            print("Distance standard rounding : \(rounded)m")

            // set text labels
            self.stepsCount.setText("\(data!.numberOfSteps ?? 0)")
            self.floorsAscCount.setText("\(data!.floorsAscended! ?? 0)")
            self.floorsDesCount.setText("\(data!.floorsDescended! ?? 0)")
            self.distanceCount.setText("\(rounded ?? 0)m.")
            self.cadenceCount.setText("\(data!.currentCadence! ?? 0)m/s")
            self.paceCount.setText("\(data!.currentPace! ?? 0)sec/m")
		}
	})
}

Build and Run on your Hardware!
