我的 iOS 应用程序中的 SSKeychain 凭据存储有一个奇怪的错误。当用户登录时，我在凭证存储中存储了一堆信息。但最近凭证商店没有设置项目。

奇怪的是，它不会一直发生。有时它会设置信息并按预期工作.. 有时凭据存储值nil在登录后返回。我的代码如下所示：

- (void)login:(id)sender {
    [SVProgressHUD show];

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager setResponseSerializer:[LoginResponseSerializer serializer]];

    __weak typeof(self)weakSelf = self;

    NSString *urlString = [NSString stringWithFormat:@"%s%s", kBaseURL, kLoginURL];

    if (self.passwordField.text && self.emailField.text) {
        NSDictionary *params = @{ @"email": self.emailField.text, @"password": self.passwordField.text};

        self.sessionManager = manager;
        [manager POST:urlString parameters:params progress:^(NSProgress * _Nonnull uploadProgress) {
            // prgress implementation
        } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
            NSDictionary *user = [responseObject objectForKey:@"user"];



            NSString *token = user[@"auth_token"];
            NSString *avatarURL = user[@"avatar_url"];
            NSString *userID = [NSString stringWithFormat: @"%@", user[@"id"]];
            NSString *firstName = user[@"first_name"];
            NSString *lastName = user[@"last_name"];
            NSString *levelOfStudy = user[@"level"];

            BOOL teecher = [user[@"teecher"] boolValue];

            [weakSelf.credentialStore setTeecher:teecher];
            [weakSelf.credentialStore setUserId:userID];
            [weakSelf.credentialStore setAvatarURL:avatarURL];
            [weakSelf.credentialStore setAuthToken:token];
            [weakSelf.credentialStore setFirstName:firstName];
            [weakSelf.credentialStore setLastName:lastName];
            [weakSelf.credentialStore setLevelOfStudy:levelOfStudy];

            [weakSelf.credentialStore setEmail:self.emailField.text];
            [weakSelf.credentialStore setPassword:self.passwordField.text];

            AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
            [manager.requestSerializer setValue:token forHTTPHeaderField:@"auth_token"];
            [manager setResponseSerializer:[CustomerResponseSerializer serializer]];
            NSString *urlString = [NSString stringWithFormat:@"%s%s", kBaseURL, kCustomerURL];

            [manager GET:urlString parameters:nil progress:^(NSProgress * _Nonnull uploadProgress) {
                // progress implementation
            } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                NSDictionary *sources = [responseObject objectForKey:@"sources"];
                NSArray *cards = (NSArray *)sources[@"data"];
                [weakSelf.credentialStore setHasCreditCard:(cards.count > 0)];
                [weakSelf.credentialStore setSignUp:false];
                [SVProgressHUD dismiss];
                [self.navigationController popViewControllerAnimated:NO];
            } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                [SVProgressHUD showErrorWithStatus:@"Failed to refresh cards."];

            }];
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
            [SVProgressHUD showErrorWithStatus:@"Login Failed"];

        }];
    }
}

正如您在成功中看到的那样，我将物品存储到凭证商店，但目前这是一个运气游戏，它在 40% 的时间里工作，而不是 60%，这是令人困惑的。我也在努力在模拟器上重新创建问题。

如果有人有任何想法？或需要查看更多代码让我知道。

我有一个类似的问题，当我添加钥匙串共享权利时它已得到修复。

我想你忘了resume你的网络电话。如果可行，请尝试以下方式，

 - (void)login:(id)sender {

[SVProgressHUD show];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager setResponseSerializer:[LoginResponseSerializer serializer]];

__weak typeof(self)weakSelf = self;

NSString *urlString = [NSString stringWithFormat:@"%s%s", kBaseURL, kLoginURL];

if (self.passwordField.text && self.emailField.text) {
    NSDictionary *params = @{ @"email": self.emailField.text, @"password": self.passwordField.text};

    self.sessionManager = manager;

    [[manager POST:urlString parameters:params progress:^(NSProgress * _Nonnull uploadProgress) {
        // prgress implementation
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSDictionary *user = [responseObject objectForKey:@"user"];


        NSString *token = user[@"auth_token"];
        NSString *avatarURL = user[@"avatar_url"];
        NSString *userID = [NSString stringWithFormat: @"%@", user[@"id"]];
        NSString *firstName = user[@"first_name"];
        NSString *lastName = user[@"last_name"];
        NSString *levelOfStudy = user[@"level"];

        BOOL teecher = [user[@"teecher"] boolValue];

        [weakSelf.credentialStore setTeecher:teecher];
        [weakSelf.credentialStore setUserId:userID];
        [weakSelf.credentialStore setAvatarURL:avatarURL];
        [weakSelf.credentialStore setAuthToken:token];
        [weakSelf.credentialStore setFirstName:firstName];
        [weakSelf.credentialStore setLastName:lastName];
        [weakSelf.credentialStore setLevelOfStudy:levelOfStudy];

        [weakSelf.credentialStore setEmail:self.emailField.text];
        [weakSelf.credentialStore setPassword:self.passwordField.text];

        AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
        [manager.requestSerializer setValue:token forHTTPHeaderField:@"auth_token"];
        [manager setResponseSerializer:[CustomerResponseSerializer serializer]];
        NSString *urlString = [NSString stringWithFormat:@"%s%s", kBaseURL, kCustomerURL];

        [[manager GET:urlString parameters:nil progress:^(NSProgress * _Nonnull uploadProgress) {
            // progress implementation
        } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
            NSDictionary *sources = [responseObject objectForKey:@"sources"];
            NSArray *cards = (NSArray *)sources[@"data"];
            [weakSelf.credentialStore setHasCreditCard:(cards.count > 0)];
            [weakSelf.credentialStore setSignUp:false];
            [SVProgressHUD dismiss];
            [self.navigationController popViewControllerAnimated:NO];
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
            [SVProgressHUD showErrorWithStatus:@"Failed to refresh cards."];

        }] resume];
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        [SVProgressHUD showErrorWithStatus:@"Login Failed"];

    }] resume];
}
