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.

On top of all the answers i found one nice solution. Actually The issue related to network connection fail for iOS 12 onword is because there is a bug in the iOS 12.0 onword. And it Yet to resolved. I had gone through the git hub community for AFNetworking related issue when app came from background and tries to do network call and fails on connection establish. I spend 3 days on this and tries many things to get to the root cause for this and found nothing. Finally i got some light in the dark when i red this blog https://github.com/AFNetworking/AFNetworking/issues/4279

据说iOS 12系统有漏洞。基本上，如果应用程序不在前台，你就不能期望网络调用完成。由于这个错误，网络呼叫被中断，我们在日志中得到网络故障。

我给你的最好的建议是，当你的应用从后台到前台有网络呼叫时，提供一些延迟。使调度中的网络调用具有一定的延迟。你永远不会得到网络呼叫掉线或连接丢失。

不要等待苹果在iOS 12中解决这个问题，因为它仍然没有修复。你可以通过为你的网络请求NSURLConnection, NSURLSession或AFNetworking或ALAMOFIRE提供一些延迟来解决这个问题。欢呼:)

这个问题持续了几个月，最后发现当我们在api域中禁用DNSSEC时，一切都ok。

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)。

当传递一个NSURLRequest到一个NSURLSession而没有设置请求的HTTPMethod时，我击中了这个错误。

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urlComponents.URL];

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

不过，添加HTTPMethod，连接就可以正常工作了

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urlComponents.URL];
[request setHTTPMethod:@"PUT"];
