ios - HKBiologicalSexObject.biologicalSex 返回 HKBiologicalSex 而不是 .Male 或 .Female

Question

我已经授权了 HealthKit，我正在像这样从 HealthKitStore 获取 BiologicalSex:

let healthKitStore:HKHealthStore = HKHealthStore()
var biologicalSexObject: HKBiologicalSexObject?
var biologicalSex: HKBiologicalSex?

do {
    biologicalSexObject = try healthKitStore.biologicalSex()
    biologicalSex = biologicalSexObject!.biologicalSex
} catch _ as NSError {
    biologicalSex = nil
    print("error reading biological sex")
}

但是，当我尝试打印 biologicalSex 时，它返回 HKBiologicalSex 而不是 .Male 或 .Female。

我在几个教程中或多或少地看到过这个确切的代码，所以我想知道在 Swift 2 中是否有任何我应该注意的语法变化。(错误处理已经改变，所以我很好奇是否其他任何值得注意的东西。)

Answer 1

执行此操作需要 biologicalSex = biologicalSexObject!.biologicalSex 的 rawValue。 BiologicalSex 的枚举如下所示:

typedef enum : NSInteger {
   HKBiologicalSexNotSet = 0,
   HKBiologicalSexFemale,
   HKBiologicalSexMale,
   HKBiologicalSexOther,
} HKBiologicalSex;

使用这些信息很容易设计一个 switch 语句来覆盖所有可能的值:

switch biologicalSex.rawValue{
    case 0:
        biologicalSex = nil
    case 1:
        biologicalSex = "Female"
    case 2:
        biologicalSex = "Male"
    case 3:
        biologicalSex = "Other"
    default:
        biologicalSex = nil
}
