我的应用程序具有“使用Apple登录”帐户功能。我想知道苹果帐户是否有退出功能。
我尝试了以下方法，但没有成功
let request = ASAuthorizationAppleIDProvider().createRequest()
request.requestedOperation = .operationLogout
let authorizationController = ASAuthorizationController(authorizationRequests: [request])
authorizationController.performRequests()
Apple当前仅允许用户执行注销（iOS / watchOS / tvOS）或显示为对我们的撤消权限。他们建议您在使用证书检查撤销之前，先获取凭据的状态，以及是否已删除所有本地信息（删除存储在用户标识符中的用户标识符）（并可能在需要时更改UI；例如，显示登录名）视图）。
let appleIDProvider = ASAuthorizationAppleIDProvider()
appleIDProvider.getCredentialState(forUserID: KeychainItem.currentUserIdentifier) { (credentialState,error) in
switch credentialState {
case .authorized:
// The Apple ID credential is valid.
break
case .revoked:
// The Apple ID credential is revoked.
break
case .notFound:
// No credential was found,so show the sign-in UI.
}
default:
break
}
}
您可以在注销时向用户提供提示，指导他们也撤消其设备的设置并收听更改通知。
,您需要从钥匙串中删除现有项目。
这是我的示例代码，使用 Apple 示例代码。

Apple 建议您在使用前获取凭据的状态以检查是否已撤销，如果已发生，则删除任何本地信息
struct KeychainItem {
init(service: String,account: String,accessGroup: String? = nil) {
self.service = service
self.account = account
self.accessGroup = accessGroup
}
static func deleteUserIdentifierFromKeychain() {
do { //please change service id to your bundle ID
try KeychainItem(service: "com.example.apple-samplecode",account: "userIdentifier").deleteItem()
} catch {
print("Unable to delete userIdentifier from keychain")
}
}
func deleteItem() throws {
// Delete the existing item from the keychain.
let query = KeychainItem.keychainQuery(withService: service,account: account,accessGroup: accessGroup)
let status = SecItemDelete(query as CFDictionary)
// Throw an error if an unexpected status was returned.
guard status == noErr || status == errSecItemNotFound else { throw KeychainError.unhandledError }
}
