Save a step count sample.
A step count sample represents the number of steps during a specific period of time. A sample should be a precise as possible, with startDate and endDate representing the range of time the steps were taken in.
saveSteps accepts an options object containing required value: number, startDate: ISO8601Timestamp, and endDate: ISO8601Timestamp.
// startDate and endDate are 30 minutes apart.
// this means the step count value occurred within those 30 minutes.
let options = {
value: 100,
startDate: (new Date(2016,6,2,6,0,0)).toISOString(),
endDate: (new Date(2016,6,2,6,30,0)).toISOString()
};AppleHealthKit.saveSteps(options, (err, res) => {
if (this._handleHKError(err, 'saveSteps')) {
return;
}
// step count sample successfully saved
});
