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。

在iOS 8模拟器上运行时，beta 5和AFNetworking 1.3也有一个问题，导致连接错误:

Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

同样的代码在iOS 7和7.1模拟器上工作得很好，我的调试代理显示失败发生在连接实际尝试之前(即没有记录请求)。

我已经追踪到NSURLConnection的失败，并向苹果报告了这个错误。见附图第5行:

.

更改为使用https允许从iOS 8模拟器连接，尽管会出现间歇性错误。

问题仍然存在于Xcode 6.01 (gm)。

重新启动模拟器解决了我的问题。

2017年1月25日，苹果发布了一份关于此错误的技术问答:

Apple Technical Q&A QA1941 Handling “The network connection was lost” Errors A: NSURLErrorNetworkConnectionLost is error -1005 in the NSURLErrorDomain error domain, and is displayed to users as “The network connection was lost”. This error means that the underlying TCP connection that’s carrying the HTTP request disconnected while the HTTP request was in progress (see below for more information about this). In some circumstances NSURLSession may retry such requests automatically (specifically, if the request is idempotent) but in other circumstances that’s not allowed by the HTTP standards. https://developer.apple.com/library/archive/qa/qa1941/_index.html#//apple_ref/doc/uid/DTS40017602

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。
