HealthKit：删除提供的锻炼的相关样本问题

Question

使用 HealthKit，我正在保存以下数据：

锻炼
活性能量
距离

我正在使用以下代码删除锻炼：

self.healthStore?.delete(workout, withCompletion: { (status, error) in

但上面的代码只是从 HealthKit 应用程序中删除了一项锻炼。我想删除锻炼及其相关样本。我该怎么做？

Answer 1

要删除关联样本，我们需要对特定 HKQuantityTypeIdentifier.

执行删除查询

要从锻炼中删除活跃能量，请参考以下代码：

 let energyBurnedQuantity = HKQuantityType.quantityType(forIdentifier: .activeEnergyBurned)

    let predicate = HKQuery.predicateForObjects(from: workout)

    let energyQuery = HKSampleQuery(sampleType: energyBurnedQuantity!, predicate: predicate, limit: 100, sortDescriptors: nil) { (query, result, error) in

        if error == nil {
            guard let resultData = result else {
                return
            }

            if resultData.count > 0 {
                self.healthStore?.delete(resultData, withCompletion: { [unowned self] (status, error) in

                    if status == true {

                        print("Successfully deleted Energy.")
                        })
                    } else {
                        print("Error \(String(describing: error?.localizedDescription))")
                    }
                })
            }
        }
    }

    self.healthStore?.execute(energyQuery)
