在 WWDC 2019 上拉背，蘋果推出了自家的 Sign in with Apple 功能员舵。iOS13之后工扎，App上如果有如”微信授權(quán)登錄”的第三方登錄泪酱，就必須提供“蘋果登錄”選項。(強制性的呦??) 蘋果官網(wǎng)有介紹 自行翻譯
一茴肥、初識SignInWithApple登錄授權(quán)原理

二坚踩、蘋果開發(fā)者后臺配置
1、配置Identifiers

2、配置項目
TARGETS配置.png
三础锐、編輯蘋果按鈕代碼
3.0嗓节、代碼引入 #import "AppDelegate.h"
#import "AppDelegate.h"
#pragma mark - 蘋果賬號登錄
#import <AuthenticationServices/AuthenticationServices.h>
@interface AppDelegate ()
@end
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
#pragma mark- 蘋果賬號登錄配置
[self observeAuthticationState];
return YES;
}
#pragma mark - Private functions 用戶注銷 AppleId 或 停止使用 Apple ID 的狀態(tài)處理
// 觀察授權(quán)狀態(tài)
- (void)observeAuthticationState {
if (@available(iOS 13.0, *)) {
// 注意 存儲用戶標(biāo)識信息需要使用鑰匙串來存儲 這里使用NSUserDefaults 做的簡單示例
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:
// 授權(quán)狀態(tài)有效
break;
case ASAuthorizationAppleIDProviderCredentialRevoked:
// 蘋果賬號登錄的憑據(jù)已被移除，需解除綁定并重新引導(dǎo)用戶使用蘋果登錄
break;
case ASAuthorizationAppleIDProviderCredentialNotFound:
// 未登錄授權(quán)郁稍，直接彈出登錄頁面赦政，引導(dǎo)用戶登錄
break;
case ASAuthorizationAppleIDProviderCredentialTransferred:
// 授權(quán)AppleID提供者憑據(jù)轉(zhuǎn)移
break;
}
}];
}
}
}
3.1、創(chuàng)建登錄按鈕(可以自己自定義按鈕耀怜，也可以使用蘋果原生按鈕)
示例以蘋果官方按鈕演示(app登錄頁面創(chuàng)建)
//登錄也引入頭文件
#import <AuthenticationServices/AuthenticationServices.h>
//添加代理
@interface ViewController ()<ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding>
@end
然后在viewDidLoad創(chuàng)建按鈕
#pragma mark - iOS13 才支持 系統(tǒng)提供的 登錄按鈕 要做下判斷
if (@available(iOS 13.0, *)){
// Sign In With Apple 按鈕
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];
}

按鈕的顏色可以自行設(shè)置恢着，黑的白的都有
3.2、點擊事件觸發(fā)的代理
#pragma mark - 蘋果登錄 發(fā)起授權(quán)登錄請求 Begin ================== http://www.reibang.com/p/483b998f2370
-(void)didAppleIDBtnClicked{
if (@available(iOS 13.0, *)) {
// Authorization 發(fā)起授權(quán)登錄請求
/*
ASAuthorizationAppleIDProvider 這個類比較簡單财破，頭文件中可以看出掰派，主要用于創(chuàng)建一個 ASAuthorizationAppleIDRequest 以及獲取對應(yīng) userID 的用戶授權(quán)狀態(tài)。
*/
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 {
// 處理不支持系統(tǒng)版本
NSLog(@"系統(tǒng)不支持Apple登錄");
}
}
#pragma mark- ASAuthorizationControllerDelegate

NSString * userID = credential.user;
// 蘋果用戶信息 如果授權(quán)過，可能無法再次獲取該信息
NSPersonNameComponents * fullName = credential.fullName;
NSString * email = credential.email;
// 服務(wù)器驗證需要使用的參數(shù)
NSString * authorizationCode = [[NSString alloc] initWithData:credential.authorizationCode encoding:NSUTF8StringEncoding];
NSString * identityToken = [[NSString alloc] initWithData:credential.identityToken encoding:NSUTF8StringEncoding];
// 用于判斷當(dāng)前登錄的蘋果賬號是否是一個真實用戶略步，取值有：unsupported描扯、unknown、likelyReal
ASUserDetectionStatus realUserStatus = credential.realUserStatus;

NSLog(@"userID: %@", userID);
NSLog(@"fullName: %@", fullName);

NSLog(@"Sign in with Apple++++++++++%@",loging);
}
else if ([authorization.credential isKindOfClass:[ASPasswordCredential class]]) {
// 用戶登錄使用現(xiàn)有的密碼憑證
ASPasswordCredential * passwordCredential = authorization.credential;
// 密碼憑證對象的用戶標(biāo)識 用戶的唯一標(biāo)識
NSString * user = passwordCredential.user;
// 密碼憑證對象的密碼
NSString * password = passwordCredential.password;
NSLog(@"userID: %@", user);
NSLog(@"password: %@", password);
} else {
}
}
// 授權(quán)失敗
- (void)authorizationController:(ASAuthorizationController *)controller didCompleteWithError:(NSError *)error API_AVAILABLE(ios(13.0)) {
NSString *errorMsg = nil;
