當訪問子類時，靜態成員不能用於類型錯誤的實例

Question

我100％確定這已被回答，但我找到的答案似乎無法適合我的解決方案。我有以下代碼遊樂場。

import Foundation 

public class AuthenticationInfo 
{ 
public class RootObject 
{ 
    var resultParameters: ResultParameters = ResultParameters() 

} 

public class ResultParameters 
{ 
    var adminInfo: AdminInfo = AdminInfo() 
    var ServerBuildNumber: Int = -1 
    var ServerIs64Bit: Bool = false 
    var ServerOSPlatform: Int = -1 
    var ServerStartTime: Int64 = -1 
    var ServerVersion: String = "" 
    var EnableLiveDataUpdates: Bool = false 
    var DelayLiveDataUpdates: String = "" 
    var SessionTimeout: Int = 0; 
    var ServerName: String = "" 
    var ServerPort: Int = -1 
    var UserName: String = "" 
    var WebAPIVersion: String = "" 
    var Locale: String = "" 
} 

public class AdminInfo 
{ 
    var AdminUUID: String = "" 
    var AllowChangeAgentClientInfoSettings: Int = -1 
    var AllowChangeAgentCustomFieldSettings: Int = -1 
    var AllowChangeAgentGeneralSettings: Int = -1 
    var AllowChangeAgentServerSettings: Int = -1 
    var AllowChangeComputerTracking: Int = -1 
    var AllowChangeComputerTrackingScreenshot: Int = -1 
    var AllowChangeCustomFields: Int = -1 
    var AllowChangeHistoryOptions: Int = -1 
    var AllowChangeMobileDeviceTracking: Int = -1 
    var AllowEnterCustomFieldData: Int = -1 
    var AllowManageDeviceUsers: Int = -1 
    var AllowManageiOSDevices: Int = -1 
    var AllowMobileRemoteControl: Int = -1 
    var AllowModifyADEPAccount: Int = -1 
    var AllowModifyBookstoreBooks: Int = -1 
    var AllowModifyMDMDeviceEnrollmentProfiles: Int = -1 
    var AllowModifyMobileActions: Int = -1 
    var AllowModifyMobileMedia: Int = -1 
    var AllowModifySDConfigProfiles: Int = -1 
    var AllowModifySDGroups: Int = -1 
    var AllowModifySDImages: Int = -1 
    var AllowModifySDPackages: Int = -1 
    var AllowModifySLPackages: Int = -1 
    var AllowModifySamsungLicenses: Int = -1 
    var AllowModifyStagingServers: Int = -1 
    var AllowModifyVPPAccount: Int = -1 
    var AllowModifyiOSApplications: Int = -1 
    var AllowModifyiOSConfigurationProfiles: Int = -1 
    var AllowModifyiOSPolicies: Int = -1 
    var AllowRemoteControl: Int = -1 
    var AllowRemoveCommandsFromHistory: Int = -1 
    var AllowRemoveComputerRecords: Int = -1 
    var AllowRemoveInventoryData: Int = -1 
    var AllowRemoveLicenseReports: Int = -1 
    var AllowRemoveSDLogEntry: Int = -1 
    var AllowRemoveiOSDeviceRecords: Int = -1 
    var AllowRemoveiOSHistoryCommands: Int = -1 
    var AllowResetSDPackges: Int = -1 
    var AllowRetrySDPackges: Int = -1 
    var AllowVPPLicenseManagement: Int = -1 
    var AllowViewAdminCenter: Int = -1 
    var AllowViewCommandsWindow: Int = -1 
    var AllowViewComputerTrackingData: Int = -1 
    var AllowViewComputerTrackingScreenshot: Int = -1 
    var AllowViewCustomFields: Int = -1 
    var AllowViewMobileDeviceTrackingData: Int = -1 
    var AllowViewSDCenter: Int = -1 
    var AllowViewSLCenter: Int = -1 
    var AllowViewServerStatus: Int = -1 
    var CanChangeServerSettings: Int = -1 
    var CanDeployAgents: Int = -1 
    var CanLogin: Int = -1 
    var CanSeeAllRecords: Int = -1 
    var CommandPermissions: Int64 = -1 
    var CommandPermissions2: Int = -1 
    var IsADUser: Int = -1 
    var IsSuperAdmin: Int = -1 
    var id: Int = -1 
    var CommandPermissionsLow32: Int64 = -1 
    var CommandPermissionsHigh32: Int = -1 
} 

} 

var lobj_AuthenticationInfo: AuthenticationInfo 
var lobj_AuthenticationInfo_RootObject: AuthenticationInfo.RootObject 

lobj_AuthenticationInfo = AuthenticationInfo() 
lobj_AuthenticationInfo_RootObject = lobj_AuthenticationInfo.RootObject 

在最後一行我收到以下錯誤：

靜態成員RootObject不能在類型AuthenticationInfo的情況下被使用。

更多信息： 這些類是由基於JSON數據的代碼生成器創建的，這些數據將從我調用的web api返回。因此，我相信這些對象的結構需要保持不變，所以當我使用EVRefelction將數據加載到類中時，結構與數據完全匹配。

有人可以幫助我得到這個工作嗎？

Answer 1

與Java不同，在swift中，所有內部類都隱式地爲static。例如：

public class Outer { 
    public class Inner { 

    } 
} 

當你想創建Inner類型的對象，你並不需要創建Outer型第一的目標。你可以這樣做：

let x = Outer.Inner() 

而且由於內部類是靜態的，它們不能與外部類的一個實例訪問：

let x = Outer() 
let y = x.Inner //Wrong! 

我想你想在這裏做的是有RootObject非靜態，因此可以從AuthenticationInfo的實例訪問它。這不能直接完成。從您的編碼風格

var x = AuthenticationInfo() 
var y = AuthenticationInfo.rootObj 

，：你應該在你的AuthenticationInfo類中創建的RootObject一個實例：

public class AuthenticationInfo { 
    public class RootObject { 
     //blah blah blah 
    } 
    // Other inner classes goes here 
    var rootObj = RootObject() 
} 

現在你可以創建的AuthenticationInfo一個實例，並訪問存儲在認證信息的rootObj我猜你是Java程序員。你明確地寫出所有類型的變量。但很快，這很少被使用。
