objective-c - 无法获取 credential.state 和 getCredentialStateForUserID

Question

我无法从方法 getCredentialStateForUserID 获取 credentialState 而其他成员返回良好。

我在 iPhone 8、iOS 13 模拟器上运行了该应用程序。

- (void)authorizationController:(ASAuthorizationController *)controller didCompleteWithAuthorization:(ASAuthorization *)authorization {

    if ([authorization.credential isKindOfClass:[ASAuthorizationAppleIDCredential class]]) {
        ASAuthorizationAppleIDCredential *credential = authorization.credential;

        NSString *state = credential.state;
        NSString *userID = credential.user;
        [[NSUserDefaults standardUserDefaults] setValue:userID forKey:currentAppleId];

        NSPersonNameComponents *fullName = credential.fullName;
        NSString *email = credential.email;
        NSString *authorizationCode = [[NSString alloc] initWithData:credential.authorizationCode encoding:NSUTF8StringEncoding];
        // refresh token

        NSString *identityToken = [[NSString alloc] initWithData:credential.identityToken encoding:NSUTF8StringEncoding];
        // access token

        ASUserDetectionStatus realUserStatus = credential.realUserStatus;

        NSLog(@"state: %@", state);
        NSLog(@"userID: %@", userID);
        NSLog(@"fullName: %@", fullName);
        NSLog(@"email: %@", email);
        NSLog(@"authorizationCode: %@", authorizationCode);
        NSLog(@"identityToken: %@", identityToken);
        NSLog(@"realUserStatus: %@", @(realUserStatus));

        ASAuthorizationAppleIDProvider *appleIDProvider = [ASAuthorizationAppleIDProvider new];

        if (userID) {
            NSString* __block errorMsg = nil;
            [appleIDProvider getCredentialStateForUserID:userID completion:^(ASAuthorizationAppleIDProviderCredentialState credentialState, NSError * _Nullable error) {
                switch (credentialState) {
                    case ASAuthorizationAppleIDProviderCredentialRevoked:
                        errorMsg = @"revoked";
                        break;
                    case ASAuthorizationAppleIDProviderCredentialAuthorized:
                        errorMsg = @"completed well";
                        break;
                    case ASAuthorizationAppleIDProviderCredentialNotFound:
                        errorMsg = @"credential not found";
                        break;
                }
                dispatch_async(dispatch_get_main_queue(), ^{
                    NSLog(@"SignInWithApple state");
                    NSLog(@"%@", errorMsg);
                });
            }];
        }
    }
}

状态:(空)

realUserStatus: 1 (ASUserDetectionStatusUnknown)

为什么我会收到这个不适当的值？
任何其他值都能很好地返回。

我收到这个错误

2019-09-09 16:28:05.859082+0900 AppleSignin[57581:3353025] [core] Credential State 请求返回错误:Error Domain=AKAuthenticationError Code=-7001 "(null)"

我也遇到了同样的情况，经过一些测试，我发现当我使用设备进行测试时它开始工作了。此外，在模拟器上，它每次都会询问姓名/电子邮件，即使用户已经同意。当我切换到设备时，这也得到了解决:第一次之后，用户不会被要求再次授予权限，而是必须提供他的 PIN/密码才能登录。
希望这可以帮助!
