I was getting this error as well, but on actual devices rather than the simulator. We noticed the error when accessing our heroku backend on HTTPS (gunicorn server), and doing POSTS with large bodys (anything over 64Kb). We use HTTP Basic Auth for authentication, and noticed the error was resolved by NOT using the didReceiveChallenge: delegate method on NSURLSession, but rather baking in the Authentication into the original request header via adding Authentiation: Basic <Base64Encoded UserName:Password>. This prevents the necessary 401 to trigger the didReceiveChallenge: delegate message, and the subsequent network connection lost.

我也有同样的问题。我不知道AFNetworking如何实现https请求，但对我来说，原因是NSURLSession的缓存问题。

在我的应用程序从safari跟踪回来后，然后发布一个http请求，“http加载失败1005”错误将出现。 如果我停止使用“[NSURLSession sharedSession]”，而是使用一个可配置的NSURLSession实例调用“dataTaskWithRequest:”方法如下，问题就解决了。

NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
config.requestCachePolicy = NSURLRequestReloadIgnoringLocalCacheData;
config.URLCache = nil;
self.session = [NSURLSession sessionWithConfiguration:config];

只要记住设置配置。URLCache = nil;。

如果问题发生在设备上，检查流量是否通过代理(设置> Wi-Fi > (info) > HTTP代理)。我已经设置好了与Charles一起使用的设备，但忘记了代理。似乎没有Charles实际运行，就会出现这个错误。

重新启动模拟器解决了我的问题。

无论何时得到错误-1005，然后需要再次调用API。

AFHTTPRequestOperationManager *manager = 
[AFHTTPRequestOperationManager manager];
[manager setSecurityPolicy:policy];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

[manager POST:<example-url>
   parameters:<parameteres>
    success:^(AFHTTPRequestOperation *operation, id responseObject) {
      NSLog(@“Success: %@", responseObject);
  } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
      NSLog(@"Error: %@", error);
      if (error.code == -1005) {
          // Call method again... 
       }
  }];

您需要再次添加调用函数的代码。确保你是调用方法一次，否则它的调用循环递归。

对于我来说，重置模拟器的内容和设置是有效的。 要重置模拟器，请遵循以下步骤:

iOS Simulator -> Reset Content and Settings ->按“Reset”(在iOS模拟器上) 即将到来的警告)
