想在swift中使用healthkit同步获取睡眠数据

编程问答 2022-05-11

问题描述

我正在尝试从 healthkit 获取 7 天的睡眠数据并在图表中显示 uit。但在这里我遇到了一些挑战

  1. 当我在此函数中传递开始日期和结束日期时，我获取了所有值，但这些值的顺序不正确。意味着我正在异步获取值。

    1. 异步调用我将它们添加到操作队列中。但我仍然收到错误。

    2. 我得到了不同的回应。所以图表也没有正确显示。而且我还必须通过调用 Api 将最后一天的数据发送到服务器。但是我最后的数据不正确。

    3. 我在循环中调用 sleep 函数。在循环中获取单个日期后，我正在调用该函数并将其添加到操作队列中。

Please anyone help me

        }
        }

    I am getting response like -

        sleep values are ("Sun",0.0)
sleep values are ("Mon",0.0)
sleep values are ("Wed",105.0)
sleep values are ("Thu",161.0)
sleep values are ("Tue",221.0)
sleep values are ("Fri",2901.0)
sleep values are ("Sat",0.0)

所以我的图表显示不正确

我获取睡眠数据的代码 -


  class func getSleepHours(from startDate: Date?,to endDate: Date?,completion: @escaping(_ result: [HKSample])-> Void)  {
        
        let typestoRead = Set([
            HKObjectType.categoryType(forIdentifier: HKCategoryTypeIdentifier.sleepAnalysis)!
        ])
        
        let typestoShare = Set([
            HKObjectType.categoryType(forIdentifier: HKCategoryTypeIdentifier.sleepAnalysis)!
        ])
        
        HKHealthStore().requestAuthorization(toShare: typestoShare,read: typestoRead) { (success,error) -> Void in
            if success == false {
                NSLog(" display not allowed")
            }
            
            if let sleepType = HKObjectType.categoryType(forIdentifier: HKCategoryTypeIdentifier.sleepAnalysis) {
                
                let formatter = DateFormatter()
                formatter.dateFormat = "yyyy/MM/dd HH:mm"
                
                let predciate = HKQuery.predicateForSamples(withStart: startDate,end: endDate,options: .strictEndDate)
                
                let sortDescriptor = NSSortDescriptor(key: HKSampleSortIdentifierEndDate,ascending: false)
                
                dispatchQueue.main.async {
                 
                let query = HKSampleQuery(sampleType: sleepType,predicate: predciate,limit: 1,sortDescriptors: [sortDescriptor]) { (query,tmpResult,error) -> Void in
                    
                    if let result = tmpResult {
                        completion(tmpResult!)
                        
                    }else{
                        print(error?.localizedDescription)
                    }
                }
                
                HKHealthStore().execute(query)
            }
            }
        }
    }
