Question

我面临以下错误代码。下面的代码是Apple Health kit读取HealthApp的葡萄糖水平。

func updateGluco（）{

let sampleType = HKSampleType.quantityTypeForIdentifier(HKQuantityTypeIdentifierBloodGlucose)
self.healthManager?.readMostRecentSample(sampleType, completion: {(mostRecentGluco, error) -> Void in

    if (error != nil){
        println("Error reading blood glucose from HealthKit store: \(error.localizedDescription)")
        return;
    }

    var glucoLocalizedString = self.kUnknownString;
    self.gluco = mostRecentGluco as? HKQuantitySample
    println("\(self.gluco?.quantity.doubleValueForUnit(HKUnit.moleUnitWithMolarMass(HKUnitMolarMassBloodGlucose)))")
    self.gluco?.quantity.doubleValueForUnit(HKUnit.moleUnitWithMolarMass(HKUnitMolarMassBloodGlucose))
    if let mmol = self.gluco?.quantity.doubleValueForUnit(HKUnit.moleUnitWithMolarMass(HKUnitMolarMassBloodGlucose)) {
        glucoLocalizedString = "\(mmol)"
    } else {
        println("error reading gluco data!")
    }
    dispatch_async(dispatch_get_main_queue(), {() -> Void in
    self.glucoLabel.text = glucoLocalizedString})
})

}

＆＃39; NSInvalidArgumentException＆＃39;，原因：＆＃39;尝试转换不兼容的单位：mg / dL，mol＆lt; 180.1558800000541＆gt;＆＃39;

此行self.gluco？.quantity.doubleValueForUnit（HKUnit.moleUnitWithMolarMass（HKUnitMolarMassBloodGlucose））

Answer 1

您尝试进行的转换无效。您无法将质量/体积（mg/dL）数量转换为仅摩尔质量（mol）。尝试转换mg/dL - ＆gt; mmol/L（每升毫摩尔），这是血糖测量的有效且常见的转换。

let mmol = HKUnit.moleUnit(with: .milli, molarMass: HKUnitMolarMassBloodGlucose)
let mmolL = mmol.unitDivided(by: HKUnit.liter())

Apple HealthKit葡萄糖水平读数给出了转换错误
