问题 I'm following some tutorials on HealthKit using swift, one of the tutorials I'm following is how to retrieve some data from the HealthKit such as weight, height age. The tutorial shows how to retrieve the most recent record for each them, the following codes shows that: func readMostRecentSample(sampleType:HKSampleType , completion: ((HKSample!, NSError!) -> Void)!) { // 1. Build the Predicate let past = NSDate.distantPast() as! NSDate let now = NSDate() let mostRecentPredicate = HKQuery

Get most recent data point from HKSampleQuery

由 大憨熊 提交于 2019-12-20 05:23:23
问题 I am having trouble getting the latest datapoint for weight using an HKSampleQuery . I have the app permissions set correctly, but HKQuantityTypeIdentifier.bodyMass is not returning the most recent data entry from the Health app. How am I supposed to grab the latest datapoint for body mass using an HKSampleQuery ? The reason I think this is because the 0.0 I set for Weight is what is returning and I am getting no console output on readWeight Edit 1 My code including the debugging process is

Getting yesterdays steps from HealthKit

由 只愿长相守 提交于 2019-12-10 14:23:46
问题 I'm building an app for personal use, and I am currently stuck on how to accurately get yesterdays steps from the healthkit. And then from there, placing it into a variable (should be easy, I know). I have a HealthKitManager class that calls the function from inside a view, and then appends that to a variable from that same view. I have scoured most of the healthKit questions, and I get back data, but I don't think it is accurate data. My phone data from yesterday is 1442 steps, but it's

Better way to run multiple HealthKit sample queries?

由 大憨熊 提交于 2019-12-01 22:50:10
问题 I have a scenario where I need to retrieve multiple sets of data from HealthKit -- body temperature, weight, and blood pressure. I need all 3 before I can continue processing because they're going to end up in a PDF. My naive first approach is going to be run one, then in the HKSampleQuery's resultsHandler call the second, then in that resultsHandler call the third. That feels kind of -- I don't know -- it feels like I'm missing something. Is there a better way or is the naive approach

Get total step count for every date in HealthKit

What's the best way to get a total step count for every day recorded in HealthKit . With HKSampleQuery's method initWithSampleType (see below) I can set a start and end date for the query using NSPredicate , but the method returns an array with many HKQuantitySamples per day. - (instancetype)initWithSampleType:(HKSampleType *)sampleType predicate:(NSPredicate *)predicate limit:(NSUInteger)limit sortDescriptors:(NSArray *)sortDescriptors resultsHandler:(void (^)(HKSampleQuery *query, NSArray *results, NSError *error))resultsHandler I guess I can query all recorded step counts and go through the
