前言

如果要上架的应用集成了三方登录，那么在审核时，苹果会强制要求应用也要集成苹果登录。如果应用没有集成一般情况下都会被审核团队给打回来。

苹果集成登录

首先，你需要在开发者中心，找到你的应用，勾选上 Sign in with Apple

勾选并保存好后， 打开Xcode, 找到项目中的Signing&Capabilities 并添加sign in with apple。

完成上面的配置以后，就可以写代码集成了
在进行代码集成前，需要先导入一个框架 AuthenticationServices.framework

import <AuthenticationServices/AuthenticationServices.h> 

并遵守ASAuthorizationControllerDelegate, ASAuthorizationControllerPresentationContextProviding协议

如果是自定义苹果按钮样式， 直接处理按钮事件

/**
 苹果登录
 */
- (void)signInWithApple {
    if (@available(iOS 13.0, *)) {
            
            ASAuthorizationAppleIDProvider *provider = [[ASAuthorizationAppleIDProvider alloc] init];
            ASAuthorizationAppleIDRequest *request = [provider createRequest];
            request.requestedScopes = @[ASAuthorizationScopeFullName, ASAuthorizationScopeEmail];
            
            ASAuthorizationController *vc = [[ASAuthorizationController alloc] initWithAuthorizationRequests:@[request]];
            vc.delegate = self;
            vc.presentationContextProvider = self;
            [vc performRequests];
            
        }
}

点击后会触发按钮事件， 接着调起苹果登录验证，验证通过后，走验证回调方法

#pragma mark 苹果集成登录

    if ([authorization.credential isKindOfClass:[ASAuthorizationAppleIDCredential class]])       {
        ASAuthorizationAppleIDCredential *credential = authorization.credential;
        
        NSLog(@"credential = %@",credential);
        
        NSString *state = credential.state;
        NSString *userID = credential.user;
        NSPersonNameComponents *fullName = credential.fullName;
        NSString *email = credential.email;

        NSString *identityToken = [[NSString alloc] initWithData:credential.identityToken encoding:NSUTF8StringEncoding]; // 用户 token
        ASUserDetectionStatus realUserStatus = credential.realUserStatus;
        NSArray *authorizedScopes = credential.authorizedScopes;
        
        NSLog(@"state: %@\nuserID: %@\nfullName: %@\nemail: %@\nauthorizationCode: %@\nidentityToken: %@\nrealUserStatus: %@\nauthorizedScopes: %@",
              state,
              userID,
              fullName,
              email,
              authorizationCode,
              identityToken,
              @(realUserStatus),
              authorizedScopes);
        
        //苹果登录，传递认证的token
        [self loginWithAppleToken:token];
    }
}

- (void)authorizationController:(ASAuthorizationController *)controller didCompleteWithError:(NSError *)error  NS_SWIFT_NAME(authorizationController(controller:didCompleteWithError:)) API_AVAILABLE(ios(13.0)){
    
    NSString *errorMsg = nil;
    switch (error.code) {
        case ASAuthorizationErrorCanceled:
            errorMsg = @"用户取消了授权请求";
            break;
        case ASAuthorizationErrorFailed:
            errorMsg = @"授权请求失败";
            break;
        case ASAuthorizationErrorInvalidResponse:
            errorMsg = @"授权请求响应无效";
            break;
        case ASAuthorizationErrorNotHandled:
            errorMsg = @"未能处理授权请求";
            break;
        case ASAuthorizationErrorUnknown:
            errorMsg = @"授权请求失败未知原因";
            break;
    }
    DDLogDebug(@"苹果授权失败:%@",errorMsg);
}

- (ASPresentationAnchor)presentationAnchorForAuthorizationController:(ASAuthorizationController *)controller API_AVAILABLE(ios(13.0)){
    return kAppDelegate.window;
}

苹果授权验证通过后，会获取到返回的Token, 客户端拿着这个token 去调用服务器Api 来校验。 校验通过后处理用户登录的逻辑就可以了。
