Voip应用程序IOS收到错误错误域= NSPOSIXErrorDomain代码= 61“该操作无法完成。连接被拒绝

Question

I'm trying to create a Voip application as this tutorial http://www.raywenderlich.com/29948/backgrounding-for-ios

But when running its getting the error

Error Domain=NSPOSIXErrorDomain Code=61 "The operation couldn’t be completed. Connection refused

When I run the source from tutorial gets same error

I think its the problem with the port assigned. How can I solve this problem. What value to give for port?

Answer 1

If you read his tutorial he mentions this. I'm sure it's your issue.

Before you run the app, you need a server with which to test it. You can use a handy little utility every Mac already has called netcat that, among other things, allows you to easily create simple text-based servers.
