在 WWDC 2019 上，苹果推出了自家的 Sign in with Apple 功能。iOS13之后，App上如果有如”微信授权登录”的第三方登录，就必须提供“苹果登录”选项。(强制性的呦😄) 苹果官网有介绍 自行翻译
一、初识SignInWithApple登录授权原理

二、苹果开发者后台配置
1、配置Identifiers

2、配置项目

三、编辑苹果按钮代码
3.0、代码引入 #import "AppDelegate.h"
#import "AppDelegate.h"
#pragma mark - 苹果账号登录
#import <AuthenticationServices/AuthenticationServices.h>
@interface AppDelegate ()
@end
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
#pragma mark- 苹果账号登录配置
[self observeAuthticationState];
return YES;
}
#pragma mark - Private functions 用户注销 AppleId 或 停止使用 Apple ID 的状态处理
// 观察授权状态
- (void)observeAuthticationState {
if (@available(iOS 13.0, *)) {
// 注意 存储用户标识信息需要使用钥匙串来存储 这里使用NSUserDefaults 做的简单示例
NSString *userIdentifier = [[NSUserDefaults standardUserDefaults] valueForKey:@"appleID"];
if (userIdentifier) {
ASAuthorizationAppleIDProvider *appleIDProvider = [[ASAuthorizationAppleIDProvider alloc] init];
[appleIDProvider getCredentialStateForUserID:userIdentifier
completion:^(ASAuthorizationAppleIDProviderCredentialState credentialState, NSError * _Nullable error) {
switch (credentialState) {
case ASAuthorizationAppleIDProviderCredentialAuthorized:
// 授权状态有效
break;
case ASAuthorizationAppleIDProviderCredentialRevoked:
// 苹果账号登录的凭据已被移除，需解除绑定并重新引导用户使用苹果登录
break;
case ASAuthorizationAppleIDProviderCredentialNotFound:
// 未登录授权，直接弹出登录页面，引导用户登录
break;
case ASAuthorizationAppleIDProviderCredentialTransferred:
// 授权AppleID提供者凭据转移
break;
}
}];
}
}
}
3.1、创建登录按钮(可以自己自定义按钮，也可以使用苹果原生按钮)
示例以苹果官方按钮演示(app登录页面创建)
//登录也引入头文件
#import <AuthenticationServices/AuthenticationServices.h>
//添加代理
@interface ViewController ()<ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding>
@end
然后在viewDidLoad创建按钮
#pragma mark - iOS13 才支持 系统提供的 登录按钮 要做下判断
if (@available(iOS 13.0, *)){
// Sign In With Apple 按钮
ASAuthorizationAppleIDButton *appleIDBtn3 = [ASAuthorizationAppleIDButton buttonWithType:ASAuthorizationAppleIDButtonTypeDefault style:ASAuthorizationAppleIDButtonStyleWhiteOutline];
appleIDBtn3.frame = CGRectMake(30, 560, self.view.bounds.size.width - 60, 40);
[appleIDBtn3 addTarget:self action:@selector(didAppleIDBtnClicked) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:appleIDBtn3];
}

按钮的颜色可以自行设置，黑的白的都有
3.2、点击事件触发的代理
#pragma mark - 苹果登录 发起授权登录请求 Begin ================== //www.greatytc.com/p/483b998f2370
-(void)didAppleIDBtnClicked{
if (@available(iOS 13.0, *)) {
// Authorization 发起授权登录请求
/*
ASAuthorizationAppleIDProvider 这个类比较简单，头文件中可以看出，主要用于创建一个 ASAuthorizationAppleIDRequest 以及获取对应 userID 的用户授权状态。
*/
ASAuthorizationAppleIDProvider * appleIDProvider = [[ASAuthorizationAppleIDProvider alloc] init];
ASAuthorizationAppleIDRequest * authAppleIDRequest = [appleIDProvider createRequest];
// ASAuthorizationPasswordRequest * passwordRequest = [[[ASAuthorizationPasswordProvider alloc] init] createRequest];
NSMutableArray <ASAuthorizationRequest *> * array = [NSMutableArray arrayWithCapacity:2];
if (authAppleIDRequest) {
[array addObject:authAppleIDRequest];
}
NSArray <ASAuthorizationRequest *> * requests = [array copy];
ASAuthorizationController * authorizationController = [[ASAuthorizationController alloc] initWithAuthorizationRequests:requests];
authorizationController.delegate = self;
authorizationController.presentationContextProvider = self;
[authorizationController performRequests];
} else {
// 处理不支持系统版本
NSLog(@"系统不支持Apple登录");
}
}
#pragma mark- ASAuthorizationControllerDelegate
// 授权成功
- (void)authorizationController:(ASAuthorizationController *)controller didCompleteWithAuthorization:(ASAuthorization *)authorization API_AVAILABLE(ios(13.0)) {
if ([authorization.credential isKindOfClass:[ASAuthorizationAppleIDCredential class]]) {
ASAuthorizationAppleIDCredential * credential = authorization.credential;
// 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。
NSString * userID = credential.user;
// 苹果用户信息 如果授权过，可能无法再次获取该信息
NSPersonNameComponents * fullName = credential.fullName;
NSString * email = credential.email;
// 服务器验证需要使用的参数
NSString * authorizationCode = [[NSString alloc] initWithData:credential.authorizationCode encoding:NSUTF8StringEncoding];
NSString * identityToken = [[NSString alloc] initWithData:credential.identityToken encoding:NSUTF8StringEncoding];
// 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
ASUserDetectionStatus realUserStatus = credential.realUserStatus;
[[NSUserDefaults standardUserDefaults] setObject:userID forKey:@"appleID"];
NSLog(@"userID: %@", userID);
NSLog(@"fullName: %@", fullName);
NSLog(@"email: %@", email);
NSLog(@"authorizationCode: %@", authorizationCode);
NSLog(@"identityToken: %@", identityToken);
NSLog(@"realUserStatus: %@", @(realUserStatus));
NSString * loging = [NSString stringWithFormat:@"参数1:%@参数2:%@参数3:%@",userID,email,identityToken];
NSLog(@"Sign in with Apple++++++++++%@",loging);
}
else if ([authorization.credential isKindOfClass:[ASPasswordCredential class]]) {
// 用户登录使用现有的密码凭证
ASPasswordCredential * passwordCredential = authorization.credential;
// 密码凭证对象的用户标识 用户的唯一标识
NSString * user = passwordCredential.user;
// 密码凭证对象的密码
NSString * password = passwordCredential.password;
NSLog(@"userID: %@", user);
NSLog(@"password: %@", password);
} else {
}
}
// 授权失败
- (void)authorizationController:(ASAuthorizationController *)controller didCompleteWithError:(NSError *)error 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;
}
NSLog(@"%@", errorMsg);
}
#pragma mark- ASAuthorizationControllerPresentationContextProviding
- (ASPresentationAnchor)presentationAnchorForAuthorizationController:(ASAuthorizationController *)controller API_AVAILABLE(ios(13.0)){
return self.view.window;
}
#pragma mark- apple授权状态 更改通知
- (void)handleSignInWithAppleStateChanged:(NSNotification *)notification
{
NSLog(@"%@", notification.userInfo);
}
#pragma mark - 苹果授权 End ========================
四、返回结果(上面已经向Apple id发起了请求，该返回给我们参数了，对吧！哈哈😄)

总结：基本上就是这样的流程操作
