Ios '；使用Apple'登录；对话框仅在使用内置的SignInWithAppleButton时调用

我正在尝试用我自己的定制风格实现一个使用Apple登录的

按钮。我遵循的代码与-相同，但当我使用自定义按钮时，对话框不会出现

工作的代码：

    SignInWithAppleButton(
        
        //Request
        onRequest: { request in
            let nonce = randomNonceString()
            currentNonce = nonce
            request.requestedScopes = [.fullName, .email]
            request.nonce = sha256(nonce)
        },
        
        //Completion
        onCompletion: { result in
            switch result {
                case .success(let authResults):
                    switch authResults.credential {
                        case let appleIDCredential as ASAuthorizationAppleIDCredential:
                        
                                guard let nonce = currentNonce else {
                                  fatalError("Invalid state: A login callback was received, but no login request was sent.")
                                }
                                guard let appleIDToken = appleIDCredential.identityToken else {
                                    fatalError("Invalid state: A login callback was received, but no login request was sent.")
                                }
                                guard let idTokenString = String(data: appleIDToken, encoding: .utf8) else {
                                  print("Unable to serialize token string from data: \(appleIDToken.debugDescription)")
                                  return
                                }
                                
                                //Creating a request for firebase
                                let credential = OAuthProvider.credential(withProviderID: "apple.com",idToken: idTokenString,rawNonce: nonce)
                        
                                //Sending Request to Firebase
                                Auth.auth().signIn(with: credential) { (authResult, error) in
                                    if (error != nil) {
                                        // Error. If error.code == .MissingOrInvalidNonce, make sure
                                        // you're sending the SHA256-hashed nonce as a hex string with
                                        // your request to Apple.
                                        print(error?.localizedDescription as Any)
                                        return
                                    }
                                    // User is signed in to Firebase with Apple.
                                    print("SUCCESS")
                                }
                        
                            //Prints the current userID for firebase
                            print("\(String(describing: Auth.auth().currentUser?.uid))")
                    default:
                        break
                                
                            }
                   default:
                        break
                }
            
        }
    )

不起作用的代码：

    SignInWithAppleButton(
        
        //Request
        onRequest: { request in
            let nonce = randomNonceString()
            currentNonce = nonce
            request.requestedScopes = [.fullName, .email]
            request.nonce = sha256(nonce)
        },
        
        //Completion
        onCompletion: { result in
            switch result {
                case .success(let authResults):
                    switch authResults.credential {
                        case let appleIDCredential as ASAuthorizationAppleIDCredential:
                        
                                guard let nonce = currentNonce else {
                                  fatalError("Invalid state: A login callback was received, but no login request was sent.")
                                }
                                guard let appleIDToken = appleIDCredential.identityToken else {
                                    fatalError("Invalid state: A login callback was received, but no login request was sent.")
                                }
                                guard let idTokenString = String(data: appleIDToken, encoding: .utf8) else {
                                  print("Unable to serialize token string from data: \(appleIDToken.debugDescription)")
                                  return
                                }
                                
                                //Creating a request for firebase
                                let credential = OAuthProvider.credential(withProviderID: "apple.com",idToken: idTokenString,rawNonce: nonce)
                        
                                //Sending Request to Firebase
                                Auth.auth().signIn(with: credential) { (authResult, error) in
                                    if (error != nil) {
                                        // Error. If error.code == .MissingOrInvalidNonce, make sure

                                        print(error?.localizedDescription as Any)
                                        return
                                    }
                                    // User is signed in to Firebase with Apple.
                                    print("SUCCESS")
                                }
                        
                            //Prints the current userID for firebase
                            print("\(String(describing: Auth.auth().currentUser?.uid))")
                    default:
                        break
                                
                            }
                   default:
                        break
                }
            
        }
    )

看法
AppleSignInButton（）
.ontapsigne{
SignInWithAppleCordinator（）.getAppleRequest（）
}

协调人

final class SignInWithAppleCoordinator: NSObject {
    
    fileprivate var currentNonce: String?
    
        private func randomNonceString(length: Int = 32) -> String {
          precondition(length > 0)
          let charset: Array<Character> =
              Array("0123456789ABCDEFGHIJKLMNOPQRSTUVXYZabcdefghijklmnopqrstuvwxyz-._")
          var result = ""
          var remainingLength = length
    
          while remainingLength > 0 {
            let randoms: [UInt8] = (0 ..< 16).map { _ in
              var random: UInt8 = 0
              let errorCode = SecRandomCopyBytes(kSecRandomDefault, 1, &random)
              if errorCode != errSecSuccess {
                fatalError("Unable to generate nonce. SecRandomCopyBytes failed with OSStatus \(errorCode)")
              }
              return random
            }
    
            randoms.forEach { random in
              if remainingLength == 0 {
                return
              }
    
              if random < charset.count {
                result.append(charset[Int(random)])
                remainingLength -= 1
              }
            }
          }
    
          return result
        }
    
    private func sha256(_ input: String) -> String {
      let inputData = Data(input.utf8)
      let hashedData = SHA256.hash(data: inputData)
      let hashString = hashedData.compactMap {
        return String(format: "%02x", $0)
      }.joined()

      return hashString
    }

    func getAppleRequest(){
        print("Begin request...")
        let appleIDProvider = ASAuthorizationAppleIDProvider()
        let nonce = randomNonceString()
        currentNonce = nonce
        let request = appleIDProvider.createRequest()
        request.requestedScopes = [.fullName, .email]
        request.nonce = sha256(nonce)
        let authorizationController = ASAuthorizationController(authorizationRequests: [request])
        authorizationController.delegate = self
        authorizationController.performRequests()
        print("Perform request...")
    }

}

extension SignInWithAppleCoordinator: ASAuthorizationControllerDelegate {
    func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
        print("Sign in to APPLE success") // THIS DOES NOT GET CALLED
    }
    func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {
        print("Sign in error APPLE ID") // THIS ALSO DOES NOT GET CALLED
    }
    
}

使用AppleCoordinator的最终类签名：NSObject{
fileprivate变量currentNonce:字符串？
private func RandomNonCrestring（长度：Int=32）->字符串{
前提条件（长度>0）
let字符集：数组=
阵列（“0123456789ABCDEFGHIJKLMNOPQRSTUVXYZABCDEFGHIJKLMNOPQRSTUVXYZ-。）
var result=“”
var remainingLength=长度
当剩余长度大于0时{
让randoms:[UInt8]=（0..<16）.map{uu}in
随机变量：UInt8=0
让errorCode=SecRandomCopyBytes（kSecRandomDefault、1和random）
如果errorCode！=errSecSuccess{
fatalError（“无法生成nonce.SecRandomCopyBytes，OSStatus\（错误代码）”失败）
}
返回随机数
}
randoms.forEach{random in
如果剩余长度==0{
返回
}
如果随机String{
让inputData=数据（input.utf8）
让hashedData=SHA256.hash（数据：inputData）
让hashString=hashedData.compactMap{
返回字符串（格式：'%02x'，$0）
}.加入
返回哈希字符串
}
func getAppleRequest（）{
打印（“开始请求…”）
让appleIDProvider=ASAuthorizationAppleIDProvider（）
设nonce=randomnocresting（）
currentNonce=nonce
let request=appleIDProvider.createRequest（）
request.requestedScopes=[.fullName，.email]
request.nonce=sha256（nonce）
让authorizationController=ASAuthorizationController（authorizationRequests:[请求]）
authorizationController.delegate=self
authorizationController.performRequests（）
打印（“执行请求…”）
}
}
带AppleCordinator的扩展名：ASAuthorizationControllerDelegate{
func authorizationController（控制器：ASAuthorizationController，已完成授权：ASAuthorization）{
print（“登录到APPLE success”）//这不会被调用
}
func authorizationController（控制器：ASAuthorizationController，DidCompleteWither错误：错误）{
print（“登录错误APPLE ID”）//这也不会被调用
}
}

知道问题出在哪里吗

我只是想复制内置按钮（
SignInWithAppleButton
）成功登录的情况，但我需要自定义样式，因此需要对自定义样式的按钮执行
操作{}
