如何获取Swift中的所有静态属性？

问题描述：

class AllDevice: Reflectable{ 

    static let LIGHT_ONOFF_NH_3A_R11_01_L12 = "LIGHT_ONOFF_NH_3A_R11_01_L12" 

    static let PLUG_ONOFF_NH_3A_R11_01_B2AC = "PLUG_ONOFF_NH_3A_R11_01_B2AC" 
    static let PLUG_POWER_NH_3A_R11_01_B2AC="PLUG_POWER_NH_3A_R11_01_B2AC" 
    static let PLUG_ENERGY_NH_3A_R11_01_B2AC="PLUG_ENERGY_NH_3A_R11_01_B2AC" 

    static let PLUG_ONOFF_NH_3A_R11_02_B2B8="PLUG_ONOFF_NH_3A_R11_02_B2B8" 
    static let PLUG_POWER_NH_3A_R11_02_B2B8="PLUG_POWER_NH_3A_R11_02_B2B8" 
    static let PLUG_ENERGY_NH_3A_R11_02_B2B8="PLUG_ENERGY_NH_3A_R11_02_B2B8" 

    static let PLUG_ONOFF_NH_3A_R11_03_B2D2="PLUG_ONOFF_NH_3A_R11_03_B2D2" 
    static let PLUG_POWER_NH_3A_R11_03_B2D2="PLUG_POWER_NH_3A_R11_03_B2D2" 
    static let PLUG_ENERGY_NH_3A_R11_03_B2D2="PLUG_ENERGY_NH_3A_R11_03_B2D2"

的方法之一是实现CustomReflectable：

class AllDevice: CustomReflectable { 

    static let LIGHT_ONOFF_NH_3A_R11_01_L12 = "LIGHT_ONOFF_NH_3A_R11_01_L12" 

    static let PLUG_ONOFF_NH_3A_R11_01_B2AC = "PLUG_ONOFF_NH_3A_R11_01_B2AC" 
    static let PLUG_POWER_NH_3A_R11_01_B2AC="PLUG_POWER_NH_3A_R11_01_B2AC" 
    static let PLUG_ENERGY_NH_3A_R11_01_B2AC="PLUG_ENERGY_NH_3A_R11_01_B2AC" 

    static let PLUG_ONOFF_NH_3A_R11_02_B2B8="PLUG_ONOFF_NH_3A_R11_02_B2B8" 
    static let PLUG_POWER_NH_3A_R11_02_B2B8="PLUG_POWER_NH_3A_R11_02_B2B8" 
    static let PLUG_ENERGY_NH_3A_R11_02_B2B8="PLUG_ENERGY_NH_3A_R11_02_B2B8" 

    static let PLUG_ONOFF_NH_3A_R11_03_B2D2="PLUG_ONOFF_NH_3A_R11_03_B2D2" 
    static let PLUG_POWER_NH_3A_R11_03_B2D2="PLUG_POWER_NH_3A_R11_03_B2D2" 
    static let PLUG_ENERGY_NH_3A_R11_03_B2D2="PLUG_ENERGY_NH_3A_R11_03_B2D2" 

    func customMirror() -> Mirror { 
     return Mirror(self, children: [ 
      "LIGHT_ONOFF_NH_3A_R11_01_L12": self.dynamicType.LIGHT_ONOFF_NH_3A_R11_01_L12, 
      "PLUG_ONOFF_NH_3A_R11_01_B2AC": self.dynamicType.PLUG_ONOFF_NH_3A_R11_01_B2AC, 
      "PLUG_POWER_NH_3A_R11_01_B2AC": self.dynamicType.PLUG_POWER_NH_3A_R11_01_B2AC 
      // etc... 
     ]) 
    } 
} 

let device = AllDevice() 
let m = Mirror(reflecting: device) 
// you can access m.children now

正如你所看到的，这是不好玩，并涉及了很多字符串字面量。如果更改分配给每种设备类型的值，则必须相应地更新镜像。

这是实现您的设备类型常量作为enum：

enum Device: String { 
    case LIGHT_ONOFF_NH_3A_R11_01_L12 = "LIGHT_ONOFF_NH_3A_R11_01_L12" 
    case PLUG_ONOFF_NH_3A_R11_01_B2AC = "PLUG_ONOFF_NH_3A_R11_01_B2AC" 
    case PLUG_POWER_NH_3A_R11_01_B2AC = "PLUG_POWER_NH_3A_R11_01_B2AC" 
    // etc.. 

    static let allDevices: [Device] = [ 
     .LIGHT_ONOFF_NH_3A_R11_01_L12, 
     .PLUG_ONOFF_NH_3A_R11_01_B2AC, 
     .PLUG_POWER_NH_3A_R11_01_B2AC 
     // etc... 
    ] 
}

这样的编译器可以为您提供一些错误检查。
