HKObserverQuery in Health Kit

Question

In which format does HKObserverQuery gets data? There is no NSArray or NSDictionary to store data then how to get. I am putting the query put not able to get all data, anyone please help?

HKObserverQuery *query =
[[HKObserverQuery alloc]
 initWithSampleType:object
 predicate:Predicate
 updateHandler:^(HKObserverQuery *query,
                 HKObserverQueryCompletionHandler completionHandler,
                 NSError *error) {
[HKUnit unitFromString:@"count/min"]];


     if (error) {

         // Perform Proper Error Handling Here...
         NSLog(@"*** An error occured while setting up the stepCount observer. %@ ***",
               error.localizedDescription);
         abort();
     }
     else{
         NSLog(@"@%",query);
         }

 }];

HKObserverQuery is not intended to deliver data to your app. The updateHandler is simply called whenever a HKSample matching your predicate is added or removed from HealthKit. It is then up to your app to perform additional queries in response, such as HKSampleQuery or HKStatisticsQuery.

Yes, there is nothing that would prevent you from doing that. – Allan Mar 30 '16 at 16:32
