我在iOS应用程序中使用SSKeychain的凭证库存在一个奇怪的错误。当用户登录时，我在证书存储中存储了一堆信息。但最近凭证商店不设置项目。SSKeychain凭证存储未正确设置？
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。其他时间，登录后凭据存储值返回nil。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"];
}];
}
}
正如你可以成功看到我存储项目的证书存储，但目前这一个运气的游戏，它的工作原理的40％的时间和没有60％，这是什么混乱。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？或需要看到更多的代码让我知道。
你只能在模拟器注意到这一点？我遇到过类似的问题，那就是数据没有被删除，而且行为也不稳定。重新启动Xcode和模拟器似乎有所帮助，但有时会再次回来。我认为这只是Xcode的最新版本而不是SSKeychain的一些奇怪之处。 –
另外，SSKeychain在撰写本文时已被弃用，以支持SAMKeychain。相同的类和行为，所以您只需要将您的SSKeychain实例重命名为SAMKeychain。 –
它实际上发生在我的设备和模拟器上。啊可能会升级到SAMKeychain，看看是否有帮助 – jckly
