Get total step count for every date in HealthKit

I am interested in obtaining the summary numbers of steps per day from Health Kit. Is there a way to do this without having to query for individual HKQuantitySamples and then summing up the data by day myself?
Use HKStatisticsCollectionQuery (reference documentation here) to compute the total number of steps taken per day.

Is there any way to get the tamper-proof date and time on iPhone?
(1 answer)
Closed 8 years ago.
So, I'm developing an app that is based on the time, but with NSDate an user can easily hack the application by changing system time of the device. So I might want to use a better method for retrieving time.
How can I do this? Is there an easy way to retrieve time from internet?
Checkout this Google Library: https://github.com/jbenet/ios-ntp
After the library is set up you can use it with the following line:
[NSDate networkDate];

I was able to retrieve the list of installed keyboards through NSUserDefaults and AppleKeyboards, but I wasn't able to find out which one is the current user selected. Anyway to do so programmatically?
Try using this:
[UITextInputMode currentInputMode].primaryLanguage
If you use NSLog, you will see something like fr-FR, pt-BR etc...
