2. “I’m not a doctor. I don’t even play one on TV.” — Me, just now.
3. “What is this, the Dark Ages?” — Doctor Leonard “Bones” McCoy
4. “Hello Computer” — Scotty
8. “So, What is is this HealthKit thing?” — You, hopefully.
10. The HealthKit Crash Course™

12. HKHealthStore self.healthStore = [[HKHealthStore alloc] init];
13. HKHealthStore // … [self.healthStore requestAuthorizationToShareTypes:writeTypes readTypes:readTypes completion:^(BOOL success, NSError *error) { // Do something! }];
14. HKObjectType HKQuantityType *stepType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount]; NSSet *writeTypes = [NSSet setWithObject:stepType]; NSSet *readTypes = [NSSet setWithObject:stepType];
15. HKObjectType HKQuantityType *stepType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount]; NSSet *writeTypes = [NSSet setWithObject:stepType]; NSSet *readTypes = [NSSet setWithObject:stepType]; [self.healthStore requestAuthorizationToShareTypes:writeTypes readTypes:readTypes completion:^(BOOL success, NSError *error) { // Do something! }];
18. HKHealthStore [self.healthStore whatElseCanYouDo];
19. HKHealthStore — Saving HKQuantityType *stepQuantityType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount]; // …
20. HKUnit HKQuantityType *stepQuantityType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount]; HKQuantity *stepQuantity = [HKQuantity quantityWithUnit:[HKUnit countUnit] doubleValue:stepCount]; // …
21. HKQuantitySample HKQuantityType *stepQuantityType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount]; HKQuantity *stepQuantity = [HKQuantity quantityWithUnit:[HKUnit countUnit] doubleValue:stepCount]; HKQuantitySample *stepSample = [HKQuantitySample quantitySampleWithType:stepQuantityType quantity:stepQuantity startDate:someStartDate endDate:someEndDate];
22. HKHealthStore — Saving // … [self.healthStore saveObject:stepSample withCompletion:^(BOOL success, NSError *error) { // You better check that error. }];
24. HKHealthStore — Querying
25. HKHealthStore — Querying HKQuantityType *stepQuantityType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount]; //…
26. HKHealthStore — Querying HKQuantityType *stepQuantityType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount]; NSPredicate *appPredicate = [HKSampleQuery predicateForObjectsFromSource:[HKSource defaultSource]]; //…
27. HKHealthStore — Querying HKQuantityType *stepQuantityType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount]; NSPredicate *appPredicate = [HKSampleQuery predicateForObjectsFromSource:[HKSource defaultSource]]; HKSampleQuery *stepQuery = [[HKSampleQuery alloc] initWithSampleType:stepQuantityType predicate:appPredicate limit:HKObjectQueryNoLimit sortDescriptors:nil resultsHandler:^(HKSampleQuery *query, NSArray *results, NSError *error) { // results will be delivered as HKSamples. In this case, HKQuantitySamples. // You should also handle that Error! }]; //…
28. HKHealthStore — Querying //… stepQuery created [self.healthStore executeQuery:stepQuery];
30. “Let’s build something cool instead.” — All of us, just now.
