与Apple登录:如何为现有应用实现它? [英] Sign In with Apple: How to achieve it for existing app?

问题描述

随着Apple在2019年6月3日发布的最新重大更新，有一项功能

With recent major updates released by Apple on 3rd June 2019, there is one feature Sign In with Apple. Information about 'how to use this' in app is available but I can see any sample source code, how to achieve this feature in your existing iOS app.

我正在寻找示例源代码，因为我不知道如何开始.

I'm looking for a sample source code, as I can't understand how to start with this.

我尝试过的操作:使用Apple登录

推荐答案

第一步是您需要 import AuthenticationServices

        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
            }
        }

如何使用Apple创建登录名

第1步

如果找到现有的iCloud钥匙串凭证或Apple ID凭证，则提示用户.将 ASAuthorizationControllerDelegate 实现为

Prompts the user if an existing iCloud Keychain credential or Apple ID credential is found. implement ASAuthorizationControllerDelegate to

func performExistingAccountSetupFlows() {
    // Prepare requests for both Apple ID and password providers.
    let requests = [ASAuthorizationAppleIDProvider().createRequest(),
                    ASAuthorizationPasswordProvider().createRequest()]
    
    // Create an authorization controller with the given requests.
    let authorizationController = ASAuthorizationController(authorizationRequests: requests)
    authorizationController.delegate = self
    authorizationController.presentationContextProvider = self
    authorizationController.performRequests()
}

extension ViewController: ASAuthorizationControllerDelegate {
    func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
        if let appleIDCredential = authorization.credential as? ASAuthorizationAppleIDCredential {
         //here is credentials . 
        }
    }
}

extension ViewController: ASAuthorizationControllerPresentationContextProviding {
    func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
        return self.view.window!
    }
}

第二步:

创建按钮

    let authorizationButton = ASAuthorizationAppleIDButton()
    authorizationButton.addTarget(self, action: #selector(handleAuthorizationAppleIDButtonPress), for: .touchUpInside)

Step3

@objc
func handleAuthorizationAppleIDButtonPress() {
    let appleIDProvider = ASAuthorizationAppleIDProvider()
    let request = appleIDProvider.createRequest()
    request.requestedScopes = [.fullName, .email]
    
    let authorizationController = ASAuthorizationController(authorizationRequests: [request])
    authorizationController.delegate = self
    authorizationController.presentationContextProvider = self
    authorizationController.performRequests()
}

可用性: iOS 13或更高版本
