swift - 测量 - 获取完整的单位名称

Question

我不确定如何使用测量来获取单位的全名。例如“公里”而不是“公里”。

let measurement = Measurement(value: 50, unit: UnitLength.meters)
let convertedMeasurement = measurement.converted(to: UnitLength.kilometers)

let value = convertedMeasurement.value // 0.05
let unitSymbol = convertedMeasurement.unit.symbol // km
let unit = convertedMeasurement.unit.? // I expect the output to be "kilometers"

Answer 1

为了获得单位的全名，您可以像这样使用MeasurementFormatter:

let formatter = MeasurementFormatter()
formatter.unitStyle = .long
let unit = formatter.string(from: convertedMeasurement.unit) //"kilometers"
