苹果登录signInWithApple踩坑—swift版(附oc参考)

一、先说踩坑问题

I.测试阶段的问题

配置后一直报错ASAuthorizationError.unknown

//失败调代理方法
func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {
//code":1000,"domain":"com.apple.AuthenticationServices.AuthorizationError
}

解决方法
- 不要使用ASAuthorizationPasswordProvider().createRequest()！！！！
- ASAuthorizationPasswordProvider().createRequest()在第一次用苹果登录授权的时候会报错ASAuthorizationErrorUnknown 1000
- 但是如果你已经授权成功登录app了，第二次登录app授权时使用ASAuthorizationPasswordProvider创建request则不会报错unknow

II.提交Appstore的注意点

使用苹果授权登录后，不能强制要求用户再使用手机号注册，否则会被拒。

二、Xcode配置

1.添加sign In With Apple

点击+，搜索signinWithApple并添加

添加成功signInWithApple3

2.配置成功后Xcode会自动添加环境变量SignInWithApple如图：

添加成功后release和debug模式都支持SignInWithApple

3.登录开发者账户检查是否配置成功

如果已经在Xcode中设置好了Team和Bundle Identifier那么配置完2.中步骤，这块会自动配置好。

3.其他注意点

个人开发者账户不支持Sign In With Apple功能

三、app端代码实现-Swift

此处使用自定义苹果登录按钮样式，设计规范参见Sign In With Apple 设计规范
也可使用苹果自带的样式（网上一堆，自行搜索）

import AuthenticationServices

class LoginView: {

    func createView() {
        if #available(iOS 13.0, *) {

            NotificationCenter.default.addObserver(self, selector: #selector(handleSignInWithAppleStateChanged(noti:)), name: ASAuthorizationAppleIDProvider.credentialRevokedNotification, object: nil)

            let btn_apple = UIButton(type: .custom)
            btn_apple.addTarget(self, action: #selector(appleLogininAction), for: .touchUpInside)
            btn_apple.setBackgroundImage(UIImage(named: "youImage"), for: .normal)
            self.addSubview(btn_apple)
            btn_apple.snp.makeConstraints {
                $0.width.equalTo(33)
            }
        }
    }

    @objc func appleLogininAction() {
        if #available(iOS 13.0, *) {
        
            //不要使用let requests = [ASAuthorizationAppleIDProvider().createRequest(), ASAuthorizationPasswordProvider().createRequest()]
//ASAuthorizationPasswordProvider().createRequest()在第一次用苹果登录授权的时候会报错ASAuthorizationErrorUnknown 1000
            let requests = [ASAuthorizationAppleIDProvider().createRequest()]
            
            let authorizationController = ASAuthorizationController(authorizationRequests: requests)

            authorizationController.delegate = self

            authorizationController.presentationContextProvider = self

            authorizationController.performRequests()

        } else {
            // 处理不支持系统版本
        }
    }

    deinit {
        if #available(iOS 13.0, *) {
            NotificationCenter.default.removeObserver(self, name: ASAuthorizationAppleIDProvider.credentialRevokedNotification, object: nil)
        }
    }
}

@available(iOS 13.0, *)
extension LoginView: ASAuthorizationControllerDelegate, ASAuthorizationControllerPresentationContextProviding {
    

    func authorizationController(controller:ASAuthorizationController, didCompleteWithAuthorization authorization:ASAuthorization) {

        if let appleIDCredential = authorization.credential as? ASAuthorizationAppleIDCredential{
            
            // 苹果用户唯一标识符，该值在同一个开发者账号下的所有 App 下是一样的，开发者可以用该唯一标识符与自己后台系统的账号体系绑定起来。
            let user = appleIDCredential.user

            // 苹果用户信息 如果授权过，可能无法再次获取该信息
            let fullName = appleIDCredential.fullName
            
            let email = appleIDCredential.email
            
            // 服务器验证需要使用的参数
            let authorizationCode = String(data: appleIDCredential.authorizationCode!, encoding: String.Encoding.utf8)!
            let identityToken = String(data: appleIDCredential.identityToken!, encoding: String.Encoding.utf8)!
            
            // 用于判断当前登录的苹果账号是否是一个真实用户，取值有：unsupported、unknown、likelyReal
            let realUserStatus = appleIDCredential.realUserStatus;
            
            //对接登录接口，处理用户登录操作

        }
    }
    
    func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {
        
        if let e = error as? ASAuthorizationError {
            var errorMsg = ""
            switch e.code {
            case .unknown:
                errorMsg = "授权请求失败未知原因"
            case .canceled:
                errorMsg = "用户取消了授权请求"
            case .invalidResponse:
                errorMsg = "授权请求响应无效"
            case .notHandled:
                errorMsg = "未能处理授权请求"
            case .failed:
                errorMsg = "授权请求失败"
            @unknown default:
                errorMsg = "授权请求失败其他原因"
            }
        }

    }
    
    func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
        return UIApplication.shared.keyWindow!
    }
