Query HealthKit for total steps for the day
<p>I am calling a function and have been trying to figure out how I can update my app to reflect the total steps for the day. Currently, the code I have only gives me the most recent quantity of steps that has been recorded. I am having trouble understanding how to use the <code>HKStatisticsQuery</code> but this is the function I have at the moment that is giving me the most recent results.</p>

<pre><code>-(void)updateStepsLabel{
        // Query to get the user's latest steps, if it exists.
HKQuantityType *stepsType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount];

[_healthStore aapl_mostRecentQuantitySampleOfType:stepsType predicate:nil completion:^(HKQuantity *mostRecentQuantity, NSError *error) {
    if (!mostRecentQuantity) {
        NSLog(@"Either an error occured fetching the user's steps information or none has been stored yet. In your app, try to handle this gracefully.");

        dispatch_async(dispatch_get_main_queue(), ^{
            self.todaysStepValueLabel.text = NSLocalizedString(@"Not available", nil);
        });
    }
    else {
        // Determine the steps in the required unit.
        HKUnit *stepUnit = [HKUnit countUnit];
        double usersWeight = [mostRecentQuantity doubleValueForUnit:stepUnit];

        // Update the user interface.
        dispatch_async(dispatch_get_main_queue(), ^{
            self.todaysStepValueLabel.text = [NSNumberFormatter localizedStringFromNumber:@(usersWeight) numberStyle:NSNumberFormatterNoStyle];
            self.todaysStepValueLabel.textColor = [UIColor blackColor];
            self.todaysStepValueLabel.font = [UIFont systemFontOfSize:25];


        });
    }
}];

}
</code></pre>
