【问题描述】：

我想在我的 ios 应用中集成“使用 Apple 登录”。我为此找到了很多代码示例，但都在 Swift 中，我需要 Objective-C。

【问题讨论】：

如果你能找到 swift 代码，那么我认为你可以很容易地在 Objective-c 中编写相同的代码！！！

【参考方案1】：

步骤-1：

出于参考目的，我从iOS 13 — Sign In with Apple Tutorial和here获取了信息

完整代码可以从github-Sign-In-with-Apple下载

添加 Apple 登录功能

在 Xcode 项目文件下，有可用的 Signing & Capabilities。按 + 并添加 “Sign In with Apple” 功能。

步骤-2

在目标 --> 通用 --> 框架中添加 AuthenticationServices 框架，在您的视图控制器中添加 #import<AuthenticationServices/AuthenticationServices.h>

第三步

在这里，我创建了 setCurrentIdentifier 对象以保存当前用户，并创建了 textview 以在屏幕中显示输出。

在您的界面中分配委托<ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding>

extern NSString* const setCurrentIdentifier;

@interface ViewController : UIViewController<ASAuthorizationControllerDelegate,ASAuthorizationControllerPresentationContextProviding>

@property (nonatomic, strong) UITextView *appleIDLoginInfoTextView;
NSString* const setCurrentIdentifier = @"setCurrentIdentifier";

第四步

在您的控制器 UI 上加载设置您的对象并观察 AppleSignInState，如下所示

 @synthesize appleIDLoginInfoTextView;

- (void)viewDidLoad 
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    if (@available(iOS 13.0, *)) 
           [self observeAppleSignInState];
           [self setupUI];
       



- (void)observeAppleSignInState 
    if (@available(iOS 13.0, *)) 
        NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
        [center addObserver:self selector:@selector(handleSignInWithAppleStateChanged:) name:ASAuthorizationAppleIDProviderCredentialRevokedNotification object:nil];
    


- (void)handleSignInWithAppleStateChanged:(id)noti     
    NSLog(@"%s", __FUNCTION__);
    NSLog(@"%@", noti);



- (void)setupUI 

    // Sign In With Apple 
    appleIDLoginInfoTextView = [[UITextView alloc] initWithFrame:CGRectMake(.0, 40.0, CGRectGetWidth(self.view.frame), CGRectGetHeight(self.view.frame) * 0.4) textContainer:nil];
    appleIDLoginInfoTextView.font = [UIFont systemFontOfSize:32.0];
    [self.view addSubview:appleIDLoginInfoTextView];


    if (@available(iOS 13.0, *)) 
    // Sign In With Apple Button
    ASAuthorizationAppleIDButton *appleIDButton = [ASAuthorizationAppleIDButton new];

    appleIDButton.frame =  CGRectMake(.0, .0, CGRectGetWidth(self.view.frame) - 40.0, 100.0);
    CGPoint origin = CGPointMake(20.0, CGRectGetMidY(self.view.frame));
    CGRect frame = appleIDButton.frame;
    frame.origin = origin;
    appleIDButton.frame = frame;
    appleIDButton.cornerRadius = CGRectGetHeight(appleIDButton.frame) * 0.25;
    [self.view addSubview:appleIDButton];
    [appleIDButton addTarget:self action:@selector(handleAuthrization:) forControlEvents:UIControlEventTouchUpInside];
    

    NSMutableString *mStr = [NSMutableString string];
    [mStr appendString:@"Sign In With Apple \n"];
    appleIDLoginInfoTextView.text = [mStr copy];



- (void)handleAuthrization:(UIButton *)sender 
    if (@available(iOS 13.0, *)) 
        // A mechanism for generating requests to authenticate users based on their Apple ID.
        ASAuthorizationAppleIDProvider *appleIDProvider = [ASAuthorizationAppleIDProvider new];

        // Creates a new Apple ID authorization request.
        ASAuthorizationAppleIDRequest *request = appleIDProvider.createRequest;
        // The contact information to be requested from the user during authentication.
        request.requestedScopes = @[ASAuthorizationScopeFullName, ASAuthorizationScopeEmail];

        // A controller that manages authorization requests created by a provider.
        ASAuthorizationController *controller = [[ASAuthorizationController alloc] initWithAuthorizationRequests:@[request]];

        // A delegate that the authorization controller informs about the success or failure of an authorization attempt.
        controller.delegate = self;

        // A delegate that provides a display context in which the system can present an authorization interface to the user.
        controller.presentationContextProvider = self;

        // starts the authorization flows named during controller initialization.
        [controller performRequests];
    

步骤 - 4

处理你的代表

 - (void)authorizationController:(ASAuthorizationController *)controller didCompleteWithAuthorization:(ASAuthorization *)authorization  API_AVAILABLE(ios(13.0))

    NSLog(@"%s", __FUNCTION__);
    NSLog(@"%@", controller);
    NSLog(@"%@", authorization);

    NSLog(@"authorization.credential：%@", authorization.credential);

    NSMutableString *mStr = [NSMutableString string];
    mStr = [appleIDLoginInfoTextView.text mutableCopy];

    if ([authorization.credential isKindOfClass:[ASAuthorizationAppleIDCredential class]]) 
        // ASAuthorizationAppleIDCredential
        ASAuthorizationAppleIDCredential *appleIDCredential = authorization.credential;
        NSString *user = appleIDCredential.user;
        [[NSUserDefaults standardUserDefaults] setValue:user forKey:setCurrentIdentifier];
        [mStr appendString:user?:@""];
        NSString *familyName = appleIDCredential.fullName.familyName;
        [mStr appendString:familyName?:@""];
        NSString *givenName = appleIDCredential.fullName.givenName;
        [mStr appendString:givenName?:@""];
        NSString *email = appleIDCredential.email;
        [mStr appendString:email?:@""];
        NSLog(@"mStr：%@", mStr);
        [mStr appendString:@"\n"];
        appleIDLoginInfoTextView.text = mStr;

     else if ([authorization.credential isKindOfClass:[ASPasswordCredential class]]) 
        ASPasswordCredential *passwordCredential = authorization.credential;
        NSString *user = passwordCredential.user;
        NSString *password = passwordCredential.password;
        [mStr appendString:user?:@""];
        [mStr appendString:password?:@""];
        [mStr appendString:@"\n"];
        NSLog(@"mStr：%@", mStr);
        appleIDLoginInfoTextView.text = mStr;
     else 
         mStr = [@"check" mutableCopy];
        appleIDLoginInfoTextView.text = mStr;
    



- (void)authorizationController:(ASAuthorizationController *)controller didCompleteWithError:(NSError *)error  API_AVAILABLE(ios(13.0))

    NSLog(@"%s", __FUNCTION__);
    NSLog(@"error ：%@", error);
    NSString *errorMsg = nil;
    switch (error.code) 
        case ASAuthorizationErrorCanceled:
            errorMsg = @"ASAuthorizationErrorCanceled";
            break;
        case ASAuthorizationErrorFailed:
            errorMsg = @"ASAuthorizationErrorFailed";
            break;
        case ASAuthorizationErrorInvalidResponse:
            errorMsg = @"ASAuthorizationErrorInvalidResponse";
            break;
        case ASAuthorizationErrorNotHandled:
            errorMsg = @"ASAuthorizationErrorNotHandled";
            break;
        case ASAuthorizationErrorUnknown:
            errorMsg = @"ASAuthorizationErrorUnknown";
            break;
    

    NSMutableString *mStr = [appleIDLoginInfoTextView.text mutableCopy];
    [mStr appendString:errorMsg];
    [mStr appendString:@"\n"];
    appleIDLoginInfoTextView.text = [mStr copy];

    if (errorMsg) 
        return;
    

    if (error.localizedDescription) 
        NSMutableString *mStr = [appleIDLoginInfoTextView.text mutableCopy];
        [mStr appendString:error.localizedDescription];
        [mStr appendString:@"\n"];
        appleIDLoginInfoTextView.text = [mStr copy];
    
    NSLog(@"controller requests：%@", controller.authorizationRequests);
    /*
     ((ASAuthorizationAppleIDRequest *)(controller.authorizationRequests[0])).requestedScopes
     <__NSArrayI 0x2821e2520>(
     full_name,
     email
     )
     */


//! Tells the delegate from which window it should present content to the user.
 - (ASPresentationAnchor)presentationAnchorForAuthorizationController:(ASAuthorizationController *)controller  API_AVAILABLE(ios(13.0))

    NSLog(@"window：%s", __FUNCTION__);
    return self.view.window;


- (void)dealloc 

    if (@available(iOS 13.0, *)) 
        [[NSNotificationCenter defaultCenter] removeObserver:self name:ASAuthorizationAppleIDProviderCredentialRevokedNotification object:nil];
    

工作完成，如果你运行代码，你会得到如下输出

【讨论】：

我可以为“与苹果一起唱歌”创建自定义按钮吗？如果是，那么苹果会拒绝此请求的应用程序吗？

@KrutarthPatel - 目前没有人使用自定义按钮，如果你想使用，使用它苹果不会拒绝。

@Anbu.Karthik 是的兄弟，我的申请被拒绝，因为没有实现用苹果登录

@KrutarthPatel - 请原谅兄弟。

@YogendraPatel，您可以使用自定义按钮。 Apple 在此处提供指南 developer.apple.com/design/human-interface-guidelines/…
