仅当我使用内置的SignInWithAppleButton时才会调用“使用Apple登录”对话框

如何解决仅当我使用内置的SignInWithAppleButton时才会调用“使用Apple登录”对话框

我正在尝试使用自己的自定义样式来实现一个Sign in with Apple按钮。我遵循与every tutorial相同的代码-但是使用自定义按钮时不会出现对话框。

有效的代码：

    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：

查看 AppleSignInButton（） .onTapGesture { SignInWithAppleCoordinator（）。getAppleRequest（） }

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
    }
    
}

知道什么问题吗？

我只是想复制内置按钮（SignInWithAppleButton）的成功登录信息，但是我需要在我的界面上自定义样式，因此需要对我的按钮执行action {}自定义样式的按钮。
