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!
