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

我有一个应用程序，可以在Xcode6-Beta1和Xcode6-Beta2与iOS7和iOS8上正常工作。但是对于Xcode6-Beta3, Beta4, Beta5，我在iOS8上面临网络问题，但在iOS7上一切都很好。我得到错误“网络连接丢失”。错误如下:

Error: ErrorDomain =NSURLErrorDomain Code=-1005 "The network connection was lost."UserInfo=0x7ba8e5b0 {NSErrorFailingURLStringKey=， _kCFStreamErrorCodeKey=57, NSErrorFailingURLKey=， NSLocalizedDescription=网络连接丢失。， _kCFStreamErrorDomainKey=1, NSUnderlyingError=0x7a6957e0 "The network connection was lost."｝

我使用AFNetworking 2。X和下面的代码片段进行网络调用:

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);
      }];

我尝试了NSURLSession，但仍然收到相同的错误。

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.

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)。

解决我的问题是重新启动模拟器，并重置内容和设置。
